cloudflare 2.10.1

Python wrapper for the Cloudflare v4 API

Installation

Two methods are provided to install this software. Use PyPi (see package details) or GitHub (see package details).

Via PyPI

$ sudo pip install cloudflare
$

Yes - that simple! (the sudo may not be needed in some cases).

Via github

$ git clone https://github.com/cloudflare/python-cloudflare
$ cd python-cloudflare
$ ./setup.py build
$ sudo ./setup.py install
$

Or whatever variance of that you want to use. There is a Makefile included.

Cloudflare name change - dropping the capital F

In Sepember/October 2016 the company modified its company name and dropped the capital F. However, for now (and for backward compatibility reasons) the class name stays the same.

Cloudflare API version 4

The Cloudflare API can be found here. Each API call is provided via a similarly named function within the CloudFlare class. A full list is provided below.

Example code

All example code is available on GitHub (see package in the examples folder).

Blog

This package was initially introduced here via Cloudflare’s blog.

Getting Started

A very simple listing of zones within your account; including the IPv6 status of the zone.

import CloudFlare

def main():
    cf = CloudFlare.CloudFlare()
    zones = cf.zones.get()
    for zone in zones:
        zone_id = zone['id']
        zone_name = zone['name']
        print("zone_id=%s zone_name=%s" % (zone_id, zone_name))

if __name__ == '__main__':
    main()

This example works when there are less than 50 zones (50 is the default number of values returned from a query like this).

Now lets expand on that and add code to show the IPv6 and SSL status of the zones. Lets also query 100 zones.

import CloudFlare

def main():
    cf = CloudFlare.CloudFlare()
    zones = cf.zones.get(params = {'per_page':100})
    for zone in zones:
        zone_id = zone['id']
        zone_name = zone['name']

        settings_ssl = cf.zones.settings.ssl.get(zone_id)
        ssl_status = settings_ssl['value']

        settings_ipv6 = cf.zones.settings.ipv6.get(zone_id)
        ipv6_status = settings_ipv6['value']

        print("zone_id=%s zone_name=%s" % (zone_id, zone_name))
        print("ssl_status=%s ipv6_status=%s" % (ssl_status, ipv6_status))

if __name__ == '__main__':
    main()

In order to query more than a single page of zones, we would have to use the raw mode (described more below). We can loop over many get calls and pass the page parameter to facilitate the paging.

Raw mode is only needed when a get request has the possibility of returning many items.

import CloudFlare

def main():
    cf = CloudFlare.CloudFlare(raw=True)
    page_number = 0
    while True:
        page_number += 1
        raw_results = cf.zones.get(params={'per_page':5,'page':page_number})
        zones = raw_results['result']

        for zone in zones:
            zone_id = zone['id']
            zone_name = zone['name']
            print("zone_id=%s zone_name=%s" % (zone_id, zone_name))

        total_pages = raw_results['result_info']['total_pages']
        if page_number == total_pages:
            break

if __name__ == '__main__':
    main()

A more complex example follows.

import CloudFlare

def main():
    zone_name = 'example.com'

    cf = CloudFlare.CloudFlare()

    # query for the zone name and expect only one value back
    try:
        zones = cf.zones.get(params = {'name':zone_name,'per_page':1})
    except CloudFlare.exceptions.CloudFlareAPIError as e:
        exit('/zones.get %d %s - api call failed' % (e, e))
    except Exception as e:
        exit('/zones.get - %s - api call failed' % (e))

    if len(zones) == 0:
        exit('No zones found')

    # extract the zone_id which is needed to process that zone
    zone = zones[0]
    zone_id = zone['id']

    # request the DNS records from that zone
    try:
        dns_records = cf.zones.dns_records.get(zone_id)
    except CloudFlare.exceptions.CloudFlareAPIError as e:
        exit('/zones/dns_records.get %d %s - api call failed' % (e, e))

    # print the results - first the zone name
    print("zone_id=%s zone_name=%s" % (zone_id, zone_name))

    # then all the DNS records for that zone
    for dns_record in dns_records:
        r_name = dns_record['name']
        r_type = dns_record['type']
        r_value = dns_record['content']
        r_id = dns_record['id']
        print('\t', r_id, r_name, r_type, r_value)

    exit(0)

if __name__ == '__main__':
    main()

Providing Cloudflare Username and API Key

When you create a CloudFlare class you can pass some combination of these four core parameters.

• email - The account email (only if an API Key is being used)

• api - The API Key (if coding prior to Issue-114 being merged)

• token - The API Token (if coding after to Issue-114)

• certtoken - Optional Origin-CA Certificate Token

This parameter controls how the data is returned from a successful call (see notes below).

• `raw - An optional Raw flag (True/False) - defaults to False

The following paramaters are for debug and/or development usage

• debug - An optional Debug flag (True/False) - defaults to False

• use_sessions - An optional Use-Sessions flag (True/False) - defaults to True

• profile - An optional Profile name (the default is Cloudflare)

• base_url - An optional Base URL (only used for development)

email=None, key=None, token=None, certtoken=None, debug=False, raw=False, use_sessions=True, profile=None, base_url=None):

Issue-114

After Issue-114 was coded and merged, the use of token and key changed; however, is backward compatible (amazingly!).

If you are using only the API Token, then don’t include the API Email. If you are coding prior to Issue-114, then the API Key can also be used as an API Token if the API Email is not used.

Python code to create class

import CloudFlare

    # A minimal call - reading values from environment variables or configuration file
    cf = CloudFlare.CloudFlare()

    # A minimal call with debug enabled
    cf = CloudFlare.CloudFlare(debug=True)

    # An authenticated call using an API Token (note the missing email)
    cf = CloudFlare.CloudFlare(token='00000000000000000000000000000000')

    # An authenticated call using an API Email and API Key
    cf = CloudFlare.CloudFlare(email='[e-mail]', key='00000000000000000000000000000000')

    # An authenticated call using an API Token and CA-Origin info
    cf = CloudFlare.CloudFlare(token='00000000000000000000000000000000', certtoken='v1.0-...')

    # An authenticated call using an API Email, API Key, and CA-Origin info
    cf = CloudFlare.CloudFlare(email='[e-mail]', key='00000000000000000000000000000000', certtoken='v1.0-...')

    # An authenticated call using using a stored profile (see below)
    cf = CloudFlare.CloudFlare(profile="CompanyX"))

If the account email and API key are not passed when you create the class, then they are retrieved from either the users exported shell environment variables or the .cloudflare.cfg or ~/.cloudflare.cfg or ~/.cloudflare/cloudflare.cfg files, in that order.

If you’re using an API Token, any cloudflare.cfg file must either not contain an email and key attribute (or they can be zero length strings) and the CLOUDFLARE_EMAIL CLOUDFLARE_API_KEY environment variable must be unset (or zero length strings), otherwise the token (CLOUDFLARE_API_TOKEN or token attribute) will not be used.

There is one call that presently doesn’t need any email or token certification (the /ips call); hence you can test without any values saved away.

Using shell environment variables

Note (for latest version of code):

• CLOUDFLARE_EMAIL has replaced CF_API_EMAIL.

• CLOUDFLARE_API_KEY has replaced CF_API_KEY.

• CLOUDFLARE_API_TOKEN has replaced CF_API_TOKEN.

• CLOUDFLARE_API_CERTKEY has replaced CF_API_CERTKEY.

Additionally, these two variables are available for testing purposes:

• CLOUDFLARE_API_EXTRAS has replaced CF_API_EXTRAS.

• CLOUDFLARE_API_URL has replaced CF_API_URL.

The older environment variable names can still be used.

$ export CLOUDFLARE_EMAIL='[e-mail]'
$ export CLOUDFLARE_API_KEY='00000000000000000000000000000000'
$ export CLOUDFLARE_API_CERTKEY='v1.0-...'
$

Or if using API Token.

$ export CLOUDFLARE_API_TOKEN='00000000000000000000000000000000'
$ export CLOUDFLARE_API_CERTKEY='v1.0-...'
$

These are optional environment variables; however, they do override the values set within a configuration file.

Using configuration file to store email and keys

The default profile name is Cloudflare for obvious reasons.

$ cat ~/.cloudflare/cloudflare.cfg
[Cloudflare]
email = [e-mail] # Do not set if using an API Token
key = 00000000000000000000000000000000
certtoken = v1.0-...
extras =
$

More than one profile can be stored within that file. Here’s an example for a work and home setup (in this example work has an API Token and home uses email/key).

$ cat ~/.cloudflare/cloudflare.cfg
[Work]
token = 00000000000000000000000000000000
[Home]
email = [e-mail]
key = 00000000000000000000000000000000
$

To select a profile, use the --profile profile-name option for cli4 command or use profile="profile-name" in the library call.

$ cli4 --profile Work /zones | jq '.[]|.name' | wc -l
      13
$

$ cli4 --profile Home /zones | jq '.[]|.name' | wc -l
       1
$

Here is the same in code.

#!/usr/bin/env python

import CloudFlare

def main():
    cf = CloudFlare.CloudFlare(profile="Work")
    ...

Advanced use of configuration file for authentication based on method

The configuration file can have values that are both generic and specific to the method. Here’s an example where a project has a different API Token for reading and writing values.

$ cat ~/.cloudflare/cloudflare.cfg
[Work]
token = 0000000000000000000000000000000000000000
token.get = 0123456789012345678901234567890123456789
$

When a GET call is processed then the second token is used. For all other calls the first token is used. Here’s a more explict verion of that config:

$ cat ~/.cloudflare/cloudflare.cfg
[Work]
token.delete = 0000000000000000000000000000000000000000
token.get = 0123456789012345678901234567890123456789
token.patch = 0000000000000000000000000000000000000000
token.post = 0000000000000000000000000000000000000000
token.put = 0000000000000000000000000000000000000000
$

This can be used with email values also.

About /certificates and certtoken

The CLOUDFLARE_API_CERTKEY or certtoken values are used for the Origin-CA /certificates API calls. You can leave certtoken in the configuration with a blank value (or omit the option variable fully).

The extras values are used when adding API calls outside of the core codebase. Technically, this is only useful for internal testing within Cloudflare. You can leave extras in the configuration with a blank value (or omit the option variable fully).

Exceptions and return values

Response data

The response is build from the JSON in the API call. It contains the results values; but does not contain the paging values.

You can return all the paging values by calling the class with raw=True. Here’s an example without paging.

#!/usr/bin/env python

import json
import CloudFlare

def main():
    cf = CloudFlare.CloudFlare()
    zones = cf.zones.get(params={'per_page':5})
    print("len=%d" % (zones.length()))

if __name__ == '__main__':
    main()

The results are as follows.

5

When you add the raw option; the APIs full structure is returned. This means the paging values can be seen.

#!/usr/bin/env python

import json
import CloudFlare

def main():
    cf = CloudFlare.CloudFlare(raw=True)
    zones = cf.zones.get(params={'per_page':5})
    print("len=%d" % (zones.length()))
    print(json.dumps(zones, indent=4, sort_keys=True))

if __name__ == '__main__':
    main()

This produces.

5
{
    "result": [
        ...
    ],
    "result_info": {
        "count": 5,
        "page": 1,
        "per_page": 5,
        "total_count": 31,
        "total_pages": 7
    }
}

A full example of paging is provided below.

Exceptions

The library will raise CloudFlareAPIError when the API call fails. The exception returns both an integer and textual message in one value.

import CloudFlare

    ...
    try
        r = ...
    except CloudFlare.exceptions.CloudFlareAPIError as e:
        exit('api error: %d %s' % (e, e))
    ...

The other raised response is CloudFlareInternalError which can happen when calling an invalid method.

In some cases more than one error is returned. In this case the return value e is also an array. You can iterate over that array to see the additional error.

import sys
import CloudFlare

    ...
    try
        r = ...
    except CloudFlare.exceptions.CloudFlareAPIError as e:
        if len(e) > 0:
            sys.stderr.write('api error - more than one error value returned!\n')
            for x in e:
                sys.stderr.write('api error: %d %s\n' % (x, x))
        exit('api error: %d %s' % (e, e))
    ...

Exception examples

Here’s examples using the CLI command cli4 of the responses passed back in exceptions.

First a simple get with a clean (non-error) response.

$ cli4 /zones/:example.com/dns_records | jq -c '.[]|{"name":.name,"type":.type,"content":.content}'
{"name":"example.com","type":"MX","content":"something.example.com"}
{"name":"something.example.com","type":"A","content":"10.10.10.10"}
$

Next a simple/single error response. This is simulated by providing incorrect authentication information.

$ CLOUDFLARE_EMAIL='[e-mail]' cli4 /zones/
cli4: /zones - 9103 Unknown X-Auth-Key or X-Auth-Email
$

More than one call can be done on the same command line. In this mode, the connection is preserved between calls.

$ cli4 /user/organizations /user/invites
...
$

Note that the output is presently two JSON structures one after the other - so less useful that you may think.

Finally, a command that provides more than one error response. This is simulated by passing an invalid IPv4 address to a DNS record creation.

$ cli4 --post name='foo' type=A content="1" /zones/:example.com/dns_records
cli4: /zones/:example.com/dns_records - 9005 Content for A record is invalid. Must be a valid IPv4 address
cli4: /zones/:example.com/dns_records - 1004 DNS Validation Error
$

Included example code

The examples folder contains many examples in both simple and verbose formats.

A DNS zone code example

#!/usr/bin/env python

import sys
import CloudFlare

def main():
    zone_name = sys.argv[1]
    cf = CloudFlare.CloudFlare()
    zone_info = cf.zones.post(data={'jump_start':False, 'name': zone_name})
    zone_id = zone_info['id']

    dns_records = [
        {'name':'foo', 'type':'AAAA', 'content':'2001:d8b::1'},
        {'name':'foo', 'type':'A', 'content':'192.168.0.1'},
        {'name':'duh', 'type':'A', 'content':'10.0.0.1', 'ttl':120},
        {'name':'bar', 'type':'CNAME', 'content':'foo'},
        {'name':'shakespeare', 'type':'TXT', 'content':"What's in a name? That which we call a rose by any other name ..."}
    ]

    for dns_record in dns_records:
        r = cf.zones.dns_records.post(zone_id, data=dns_record)
    exit(0)

if __name__ == '__main__':
    main()

A DNS zone delete code example (be careful)

#!/usr/bin/env python

import sys
import CloudFlare

def main():
    zone_name = sys.argv[1]
    cf = CloudFlare.CloudFlare()
    zone_info = cf.zones.get(params={'name': zone_name})
    zone_id = zone_info['id']

    dns_name = sys.argv[2]
    dns_records = cf.zones.dns_records.get(zone_id, params={'name':dns_name + '.' + zone_name})
    for dns_record in dns_records:
        dns_record_id = dns_record['id']
        r = cf.zones.dns_records.delete(zone_id, dns_record_id)
    exit(0)

if __name__ == '__main__':
    main()

CLI

All API calls can be called from the command line. The command will convert domain names prefixed with a colon (:) into zone_identifiers: e.g. to view example.com you must use cli4 /zones/:example.com (the zone ID cannot be used).

$ cli4 [-V|--version] [-h|--help] [-v|--verbose] [-q|--quiet] [-j|--json] [-y|--yaml] [-r|--raw] [-d|--dump] [--get|--patch|--post|--put|--delete] [item=value ...] /command...

CLI parameters for POST/PUT/PATCH

For API calls that need to pass data or parameters there is various formats to use.

The simplest form is item=value. This passes the value as a string within the APIs JSON data.

If you need a numeric value passed then == can be used to force the value to be treated as a numeric value within the APIs JSON data. For example: item==value.

if you need to pass a list of items; then [] can be used. For example:

pool_id1="11111111111111111111111111111111"
pool_id2="22222222222222222222222222222222"
pool_id3="33333333333333333333333333333333"
cli4 --post global_pools="[ ${pool_id1}, ${pool_id2}, ${pool_id3} ]" region_pools="[ ]" /user/load_balancers/maps

Data or parameters can be either named or unnamed. It can not be both. Named is the majority format; as described above. Unnamed parameters simply don’t have anything before the = sign, as in =value. This format is presently only used by the Cloudflare Load Balancer API calls. For example:

cli4 --put ="00000000000000000000000000000000" /user/load_balancers/maps/:00000000000000000000000000000000/region/:WNAM

Data can also be uploaded from file contents. Using the item=@filename format will open the file and the contents uploaded in the POST.

CLI output

The output from the CLI command is in JSON or YAML format (and human readable). This is controled by the –yaml or –json flags (JSON is the default).

Simple CLI examples

• cli4 /user/billing/profile

• cli4 /user/invites

• cli4 /zones/:example.com

• cli4 /zones/:example.com/dnssec

• cli4 /zones/:example.com/settings/ipv6

• cli4 --put /zones/:example.com/activation_check

• cli4 /zones/:example.com/keyless_certificates

• cli4 /zones/:example.com/analytics/dashboard

More complex CLI examples

Here is the creation of a DNS entry, followed by a listing of that entry and then the deletion of that entry.

$ $ cli4 --post name="test" type="A" content="10.0.0.1" /zones/:example.com/dns_records
{
    "id": "00000000000000000000000000000000",
    "name": "test.example.com",
    "type": "A",
    "content": "10.0.0.1",
    ...
}
$

$ cli4 /zones/:example.com/dns_records/:test.example.com | jq '{"id":.id,"name":.name,"type":.type,"content":.content}'
{
  "id": "00000000000000000000000000000000",
  "name": "test.example.com",
  "type": "A",
  "content": "10.0.0.1"
}

$ cli4 --delete /zones/:example.com/dns_records/:test.example.com | jq -c .
{"id":"00000000000000000000000000000000"}
$

There’s the ability to handle dns entries with multiple values. This produces more than one API call within the command.

$ cli4 /zones/:example.com/dns_records/:test.example.com | jq -c '.[]|{"id":.id,"name":.name,"type":.type,"content":.content}'
{"id":"00000000000000000000000000000000","name":"test.example.com","type":"A","content":"192.168.0.1"}
{"id":"00000000000000000000000000000000","name":"test.example.com","type":"AAAA","content":"2001:d8b::1"}
$

Here are the cache purging commands.

$ cli4 --delete purge_everything=true /zones/:example.com/purge_cache | jq -c .
{"id":"00000000000000000000000000000000"}
$

$ cli4 --delete files='[http://example.com/css/styles.css]' /zones/:example.com/purge_cache | jq -c .
{"id":"00000000000000000000000000000000"}
$

$ cli4 --delete files='[http://example.com/css/styles.css,http://example.com/js/script.js]' /zones/:example.com/purge_cache | jq -c .
{"id":"00000000000000000000000000000000"}
$

$ cli4 --delete tags='[tag1,tag2,tag3]' /zones/:example.com/purge_cache | jq -c .
cli4: /zones/:example.com/purge_cache - 1107 Only enterprise zones can purge by tag.
$

A somewhat useful listing of available plans for a specific zone.

$ cli4 /zones/:example.com/available_plans | jq -c '.[]|{"id":.id,"name":.name}'
{"id":"00000000000000000000000000000000","name":"Pro Website"}
{"id":"00000000000000000000000000000000","name":"Business Website"}
{"id":"00000000000000000000000000000000","name":"Enterprise Website"}
{"id":"0feeeeeeeeeeeeeeeeeeeeeeeeeeeeee","name":"Free Website"}
$

Cloudflare CA CLI examples

Here’s some Cloudflare CA examples. Note the need of the zone_id= parameter with the basic /certificates call.

$ cli4 /zones/:example.com | jq -c '.|{"id":.id,"name":.name}'
{"id":"12345678901234567890123456789012","name":"example.com"}
$

$ cli4 zone_id=12345678901234567890123456789012 /certificates | jq -c '.[]|{"id":.id,"expires_on":.expires_on,"hostnames":.hostnames,"certificate":.certificate}'
{"id":"123456789012345678901234567890123456789012345678","expires_on":"2032-01-29 22:36:00 +0000 UTC","hostnames":["*.example.com","example.com"],"certificate":"-----BEGIN CERTIFICATE-----\n ... "}
{"id":"123456789012345678901234567890123456789012345678","expires_on":"2032-01-28 23:23:00 +0000 UTC","hostnames":["*.example.com","example.com"],"certificate":"-----BEGIN CERTIFICATE-----\n ... "}
{"id":"123456789012345678901234567890123456789012345678","expires_on":"2032-01-28 23:20:00 +0000 UTC","hostnames":["*.example.com","example.com"],"certificate":"-----BEGIN CERTIFICATE-----\n ... "}
$

A certificate can be viewed via a simple GET request.

$ cli4 /certificates/:123456789012345678901234567890123456789012345678
{

Creating a certificate. This is done with a POST request. Note the use of == in order to pass a decimal number (vs. string) in JSON. The CSR is not shown for simplicity sake.

$ CSR=`cat example.com.csr`
$ cli4 --post hostnames='["example.com","*.example.com"]' requested_validity==365 request_type="origin-ecc" csr="$CSR" /certificates
{
    "certificate": "-----BEGIN CERTIFICATE-----\n ... ",

Deleting a certificate can be done with a DELETE call.

$ cli4 --delete /certificates/:123456789012345678901234567890123456789012345678
{

Paging CLI examples

The –raw command provides access to the paging returned values. See the API documentation for all the info. Here’s an example of how to page thru a list of zones (it’s included in the examples folder as example_paging_thru_zones.sh).

:
tmp=/tmp/$$_
trap "rm ${tmp}; exit 0" 0 1 2 15
PAGE=0
while true
do
        cli4 --raw per_page=5 page=${PAGE} /zones > ${tmp}
        domains=`jq -c '.|.result|.[]|.name' < ${tmp} | tr -d '"'`
        result_info=`jq -c '.|.result_info' < ${tmp}`
        COUNT=`      echo "${result_info}" | jq .count`
        PAGE=`       echo "${result_info}" | jq .page`
        PER_PAGE=`   echo "${result_info}" | jq .per_page`
        TOTAL_COUNT=`echo "${result_info}" | jq .total_count`
        TOTAL_PAGES=`echo "${result_info}" | jq .total_pages`
        echo COUNT=${COUNT} PAGE=${PAGE} PER_PAGE=${PER_PAGE} TOTAL_COUNT=${TOTAL_COUNT} TOTAL_PAGES=${TOTAL_PAGES} -- ${domains}
        if [ "${PAGE}" == "${TOTAL_PAGES}" ]
        then
                ## last section
                break
        fi
        # grab the next page
        PAGE=`expr ${PAGE} + 1`
done

It produces the following results.

COUNT=5 PAGE=1 PER_PAGE=5 TOTAL_COUNT=31 TOTAL_PAGES=7 -- accumsan.example auctor.example consectetur.example dapibus.example elementum.example
COUNT=5 PAGE=2 PER_PAGE=5 TOTAL_COUNT=31 TOTAL_PAGES=7 -- felis.example iaculis.example ipsum.example justo.example lacus.example

COUNT=5 PAGE=4 PER_PAGE=5 TOTAL_COUNT=31 TOTAL_PAGES=7 -- porttitor.example potenti.example pretium.example purus.example quisque.example
COUNT=5 PAGE=5 PER_PAGE=5 TOTAL_COUNT=31 TOTAL_PAGES=7 -- sagittis.example semper.example sollicitudin.example suspendisse.example tortor.example
COUNT=1 PAGE=7 PER_PAGE=5 TOTAL_COUNT=31 TOTAL_PAGES=7 -- varius.example vehicula.example velit.example velit.example vitae.example
COUNT=5 PAGE=6 PER_PAGE=5 TOTAL_COUNT=31 TOTAL_PAGES=7 -- vivamus.example

Paging thru lists (using cursors)

Some API calls use cursors to read beyond the initally returned values. See the API page in order to see which API calls do this.

$ ACCOUNT_ID="00000000000000000000000000000000"
$ LIST_ID="00000000000000000000000000000000"
$
$ cli4 --raw /accounts/::${ACCOUNT_ID}/rules/lists/::${LIST_ID}/items > /tmp/page1.json
$ after=`jq -r '.result_info.cursors.after' < /tmp/page1.json`
$ echo "after=$after"
after=Mxm4GVmKjYbFjy2VxMPipnJigm1M_s6lCS9ABR9wx-RM2A
$

Once we have the after value, we can pass it along in order to read the next hunk of values. We finish when after returns as null (or isn’t present).

$ cli4 --raw cursor="$after" /accounts/::${ACCOUNT_ID}/rules/lists/::${LIST_ID}/items > /tmp/page2.json
$ after=`jq -r '.result_info.cursors.after' < /tmp/page2.json`
$ echo "after=$after"
after=null
$

We can see the results now in two files.

$ jq -c '.result[]' < /tmp/page1.json | wc -l
      25
$

$ jq -c '.result[]' < /tmp/page2.json | wc -l
       5
$

$ for f in /tmp/page?.json ; do jq -r '.result[]|.id,.ip,.comment' < $f | paste - - - ; done | column -s'   ' -t

The result_info.cursors area also contains a before value for reverse scrolling.

As with per_page scrolling, raw mode is used.

Zone file upload (i.e. import) CLI examples (uses BIND format files)

Refer to Import DNS records on API documentation for this feature.

$ cat zone.txt

    "total_records_parsed": 4
}
$

Zone file upload (i.e. import) Python examples (uses BIND format files)

Because import is a reserved word in Python there needs to be a slight workaround to calling this within code.

#
# "import" is a reserved word and hence this code - it's ugly; but correct.
#
dns_records_import = getattr(cf.zones.dns_records, 'import')
r = dns_records_import.post(zone_id, files={'file':fd})

See (examples/example_dns_import.py)[examples/example_dns_import.py] for working code.

Zone file download (i.e. export) CLI examples (uses BIND format files)

The following is documented within the Advanced option of the DNS page within the Cloudflare portal.

$ cli4 /zones/:example.com/dns_records/export | egrep -v '^;;|^$'
$ORIGIN .
@       3600    IN      SOA     example.com.    root.example.com.       (
                2025552311      ; serial
                7200            ; refresh
                3600            ; retry
                86400           ; expire
                3600)           ; minimum
example.com.    300     IN      NS      REPLACE&ME$WITH^YOUR@NAMESERVER.
record4.example.com.    300     IN      TXT     "some text"
record3.example.com.    300     IN      CNAME   record1.example.com.
record1.example.com.    300     IN      A       10.0.0.1
record2.example.com.    300     IN      AAAA    2001:d8b::2
$

The egrep is used for documentation brevity.

This can also be done via Python code with the following example.

#!/usr/bin/env python
import sys
import CloudFlare

def main():
    zone_name = sys.argv[1]
    cf = CloudFlare.CloudFlare()

    zones = cf.zones.get(params={'name': zone_name})
    zone_id = zones[0]['id']

    dns_records = cf.zones.dns_records.export.get(zone_id)
    for l in dns_records.splitlines():
        if len(l) == 0 or l[0] == ';':
            continue
        print(l)
    exit(0)

if __name__ == '__main__':
    main()

Cloudflare Workers

Cloudflare Workers are described on the Cloudflare blog at here and here, with the beta release announced here.

The Python libraries now support the Cloudflare Workers API calls. The following javascript is lifted from https://cloudflareworkers.com/ and slightly modified.

$ cat modify-body.js
addEventListener("fetch", event => {
  event.respondWith(fetchAndModify(event.request));
});

async function fetchAndModify(request) {
  console.log("got a request:", request);

  // Send the request on to the origin server.
  const response = await fetch(request);

  // Read response body.
  const text = await response.text();

  // Modify it.
  const modified = text.replace(
  "<body>",
  "<body style=\"background: #ff0;\">");

  // Return modified response.
  return new Response(modified, {
    status: response.status,
    statusText: response.statusText,
    headers: response.headers
  });
}
$

Here’s the website with it’s simple <body> statement

$ curl -sS https://example.com/ | fgrep '<body'
  <body>
$

Now lets add the script. Looking above, you will see that it’s simple action is to modify the <body> statement and make the background yellow.

$ cli4 --put @- /zones/:example.com/workers/script < modify-body.js
{
    "etag": "1234567890123456789012345678901234567890123456789012345678901234",
    "id": "example-com",
    "modified_on": "2018-02-15T00:00:00.000000Z",
    "script": "addEventListener(\"fetch\", event => {\n  event.respondWith(fetchAndModify(event.request));\n});\n\nasync function fetchAndModify(request) {\n  console.log(\"got a request:\", request);\n\n  // Send the request on to the origin server.\n  const response = await fetch(request);\n\n  // Read response body.\n  const text = await response.text();\n\n  // Modify it.\n  const modified = text.replace(\n  \"<body>\",\n  \"<body style=\\\"background: #ff0;\\\">\");\n\n  // Return modified response.\n  return new Response(modified, {\n    status: response.status,\n    statusText: response.statusText,\n    headers: response.headers\n  });\n}\n",
    "size": 603
}
$

The following call checks that the script is associated with the zone. In this case, it’s the only script added by this user.

$ cli4 /user/workers/scripts
[
    {
        "created_on": "2018-02-15T00:00:00.000000Z",
        "etag": "1234567890123456789012345678901234567890123456789012345678901234",
        "id": "example-com",
        "modified_on": "2018-02-15T00:00:00.000000Z"
    }
]
$

Next step is to make sure a route is added for that script on that zone.

$ cli4 --post pattern="example.com/*" script="example-com" /zones/:example.com/workers/routes
{
    "id": "12345678901234567890123456789012"
}
$

$ cli4 /zones/:example.com/workers/routes
[
    {
        "id": "12345678901234567890123456789012",
        "pattern": "example.com/*",
        "script": "example-com"
    }
]
$

With that script added to the zone and the route added, we can now see the website has been modified because of the Cloudflare Worker.

$ curl -sS https://example.com/ | fgrep '<body'
  <body style="background: #ff0;">
$

All this can be removed; hence bringing the website back to its initial state.

$ cli4 --delete /zones/:example.com/workers/script
12345678901234567890123456789012
$ cli4 --delete /zones/:example.com/workers/routes/:12345678901234567890123456789012
true
$

$ curl -sS https://example.com/ | fgrep '<body'
  <body>
$

Refer to the Cloudflare Workers API documentation for more information.

Cloudflare GraphQL

The GraphQL interface can be accessed via the command line or via Python.

query="""
  query {
    viewer {
        zones(filter: {zoneTag: "%s"} ) {
        httpRequests1dGroups(limit:40, filter:{date_lt: "%s", date_gt: "%s"}) {
          sum { countryMap { bytes, requests, clientCountryName } }
          dimensions { date }
        }
      }
    }
  }
""" % (zone_id, date_before[0:10], date_after[0:10])

r = cf.graphql.post(data={'query':query})

httpRequests1dGroups = zone_info = r['data']['viewer']['zones'][0]['httpRequests1dGroups']

See the examples/example_graphql.sh and examples/example_graphql.py files for working examples. Here is the working example of the shell version:

For more information on how to use GraphQL at Cloudflare, refer to the Cloudflare GraphQL Analytics API. It contains a full overview of Cloudflare’s GraphQL features and keywords.

Implemented API calls

The –dump argument to cli4 will produce a list of all the call implemented within the library.

$ cli4 --dump
/certificates
/ips
/organizations
...
/zones/ssl/analyze
/zones/ssl/certificate_packs
/zones/ssl/verification
$

Table of commands

An automatically generated table of commands is provided here.

Adding extra API calls manually

Extra API calls can be added via the configuration file

$ cat ~/.cloudflare/cloudflare.cfg
[Cloudflare]
extras =
    /client/v4/command
    /client/v4/command/:command_identifier
    /client/v4/command/:command_identifier/settings
$

While it’s easy to call anything within Cloudflare’s API, it’s not very useful to add items in here as they will simply return API URL errors. Technically, this is only useful for internal testing within Cloudflare.

Python 2.x vs 3.x support

As of May/June 2016 the code is now tested against pylint. This was required in order to move the codebase into Python 3.x. The motivation for this came from Danielle Madeley (danni).

[STRIKEOUT:While the codebase has been edited to run on Python 3.x, there’s not been enough Python 3.x testing performed.] [STRIKEOUT:If you can help in this regard; please contact the maintainers.]

As of January 2020 the code is Python3 clean.

As of January 2020 the code is shipped up to pypi with Python2 support removed.

As of January 2020 the code is Python3.8 clean. The new SyntaxWarning messages (i.e. SyntaxWarning: "is" with a literal. Did you mean "=="?) meant minor edits were needed.
