http_pycurl rewraps pycurl.

Project description

http-pycurl Introduction

http-pycurl repackaged the pycurl for better use.

Thanks to the author of the requests.Some code comes from requests.

The API it exposes is similar to the requests

Installation

You should install pycurl first.

pip install http-pycurl

Quickstart

Make a Request

Begin by importing the http_pycurl module.

>>> import http_pycurl as requests

Currently only supports three request methods.

GET

>>> r = requests.get('https://httpbin.org/get')
>>> r.status_code
200
>>> r.headers
{'Access-Control-Allow-Credentials': 'true', 'Access-Control-Allow-Origin': '*', 'Content-Encoding': 'gzip', 'Content-Type': 'application/json', 'Date': 'Thu, 21 Nov 2019 05:56:51 GMT', 'Referrer-Policy': 'no-referrer-when-downgrade', 'Server': 'nginx', 'X-Content-Type-Options': 'nosniff', 'X-Frame-Options': 'DENY', 'X-XSS-Protection': '1; mode=block', 'Content-Length': '264', 'Connection': 'keep-alive'}
>>> r.text
'{\n  "args": {}, \n  "headers": {\n    "Accept": "*/*", \n    "Accept-Encoding": "gzip, deflate", \n    "Host": "httpbin.org", \n    "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.97 Safari/537.36"\n  }, \n  "origin": "xxx.xxx.xxx.xxx, xxx.xxx.xxx.xxx", \n  "url": "https://httpbin.org/get"\n}\n'
>>> r.json()
{'args': {}, 'headers': {'Accept': '*/*', 'Accept-Encoding': 'gzip, deflate', 'Host': 'httpbin.org', 'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.97 Safari/537.36'}, 'origin': 'xxx.xxx.xxx.xxx, xxx.xxx.xxx.xxx', 'url': 'https://httpbin.org/get'}

POST

>>> post_data = {"foo": "bar"}
>>> r = requests.post("https://httpbin.org/post", data=post_data)
>>> r.json()
{'args': {}, 'data': '', 'files': {}, 'form': {'foo': 'bar'}, 'headers': {'Accept': '*/*', 'Accept-Encoding': 'gzip, deflate', 'Content-Length': '7', 'Content-Type': 'application/x-www-form-urlencoded', 'Host': 'httpbin.org', 'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.97 Safari/537.36'}, 'json': None, 'origin': 'xxx.xxx.xxx.xxx, xxx.xxx.xxx.xxx', 'url': 'https://httpbin.org/post'}
>>>

HEAD

>>> r = requests.head("https://httpbin.org/get")
>>> r.status_code
200
>>> r.text
''

Passing Parameters In URLs

>>> payload = {'key1': 'value1', 'key2': 'value2'}
>>> r = requests.get('https://httpbin.org/get', params=payload)
>>> r.url
'https://httpbin.org/get?key1=value1&key2=value2'

You can also pass a list of items as a value:

>>> payload = {'key1': 'value1', 'key2': ['value2', 'value3']}
>>> r = requests.get('https://httpbin.org/get', params=payload)
>>> r.url
'https://httpbin.org/get?key1=value1&key2=value2&key2=value3'

Custom Headers

If you’d like to add HTTP headers to a request, simply pass in a dict to the headers parameter.

>>> url = 'https://httpbin.org/get'
>>> headers = {'user-agent': 'http_pycurl/1.0.0'}
>>> r = requests.get(url, headers=headers)
>>> r.json()
{'args': {}, 'headers': {'Accept': '*/*', 'Host': 'httpbin.org', 'User-Agent': 'http_pycurl/1.0.0'}, 'origin': 'xxx.xxx.xxx.xxx, xxx.xxx.xxx.xxx', 'url': 'https://httpbin.org/get'}

Cookies

To send your own cookies to the server, you can use the cookies parameter:

>>> url = 'https://httpbin.org/cookies'
>>> cookies = dict(cookies_are='working')
>>> r = requests.get(url, cookies=cookies)
>>> r.text
'{"cookies": {"cookies_are": "working"}}'

Timeouts

You can tell Requests to stop waiting for a response after a given number of seconds with the timeout parameter. The timout must be greater than 1 second.

>>> url = 'https://httpbin.org/get'
>>> r = requests.get(url, timeout=1)
http_pycurl.exceptions.Timeout

Session

Session saves different cookies according to the domain name.And, it automatically sends cookies based on the domain name.

>>> s = requests.Session()
>>> s.get('https://httpbin.org/cookies/set/sessioncookie/123456789')
>>> r = s.get('https://httpbin.org/cookies')
>>> print(r.text)
'{"cookies": {"sessioncookie": "123456789"}}'

Why did I develop this package

When I crawled some websites, I found that they had a anit-spider by http message format.

Due to requests' http message format, the content of the website could not be obtained correctly.

However, pycurl can grab the right content. So I repackaged the pycurl for better use.
