A Python library to push web resources into public web archives

Project description

A Tool To Push Web Resources Into Web Archives

Archive Now (archivenow) currently is configured to push resources into six public web archives. You can easily add more archives by writing a new archive handler (e.g., myarchive_handler.py) and place it inside the folder “handlers”.

As explained below, this library can be used through:

  • Command Line Interface (CLI)
  • A Web Service
  • A Docker Container
  • Python

Installing

The latest release of archivenow can be installed using pip:

$ pip install archivenow

The latest development version containing changes not yet released can be installed from source:

$ git clone git@github.com:oduwsdl/archivenow.git
$ cd archivenow
$ pip install -r requirements.txt
$ pip install ./

CLI USAGE

Usage of sub-commands in archivenow can be accessed through providing the -h or –help flag, like any of the below.

$ archivenow -h
usage: archivenow.py [-h] [--mg] [--wc] [--cc] [--cc_api_key [CC_API_KEY]]
                     [--is] [--st] [--ia] [--warc [WARC]] [-v] [--all]
                     [--server] [--host [HOST]] [--agent [AGENT]]

Examples

Example 1

To save the web page (www.foxnews.com) in the Internet Archive:

$ archivenow --ia www.foxnews.com
https://web.archive.org/web/20170209135625/http://www.foxnews.com

Example 2

By default, the web page (e.g., www.foxnews.com) will be saved in the Internet Archive if no optional arguments are provided:

$ archivenow www.foxnews.com
https://web.archive.org/web/20170215164835/http://www.foxnews.com

Example 3

To save the web page (www.foxnews.com) in the Internet Archive (archive.org) and Archive.is:

$ archivenow --ia --is www.foxnews.com
https://web.archive.org/web/20170209140345/http://www.foxnews.com
http://archive.is/fPVyc

Example 4

To save the web page (https://nypost.com/) in all configured web archives. In addition to preserving the page in all configured archives, this command will also locally create a WARC file:

$ archivenow --all https://nypost.com/ --cc_api_key $Your-Perma-CC-API-Key
http://archive.is/dcnan
https://perma.cc/53CC-5ST8
https://web.archive.org/web/20181002081445/https://nypost.com/
https://megalodon.jp/2018-1002-1714-24/https://nypost.com:443/
http://www.webcitation.org/72ramyxT2
https://Archive.st/archive/2018/10/nypost.com/h5m1/nypost.com/index.html
https_nypost.com__96ec2300.warc

Example 5

To download the web page (https://nypost.com/) and create a WARC file:

$ archivenow --warc=mypage --agent=wget https://nypost.com/
mypage.warc

Server

You can run archivenow as a web service. You can specify the server address and/or the port number (e.g., –host localhost –port 12345)

$ archivenow --server

Running on http://0.0.0.0:12345/ (Press CTRL+C to quit)

Example 6

To save the web page (www.foxnews.com) in The Internet Archive through the web service:

$ curl -i http://0.0.0.0:12345/ia/www.foxnews.com

    HTTP/1.0 200 OK
    Content-Type: application/json
    Content-Length: 95
    Server: Werkzeug/0.11.15 Python/2.7.10
    Date: Tue, 02 Oct 2018 08:20:18 GMT

    {
      "results": [
        "https://web.archive.org/web/20181002082007/http://www.foxnews.com"
      ]
    }

Example 7

To save the web page (www.foxnews.com) in all configured archives though the web service:

$ curl -i http://0.0.0.0:12345/all/www.foxnews.com

    HTTP/1.0 200 OK
    Content-Type: application/json
    Content-Length: 385
    Server: Werkzeug/0.11.15 Python/2.7.10
    Date: Tue, 02 Oct 2018 08:23:53 GMT

    {
      "results": [
        "Error (The Perma.cc Archive): An API Key is required ",
        "http://archive.is/ukads",
        "https://web.archive.org/web/20181002082007/http://www.foxnews.com",
        "http://Archive.st/ikxq",
        "Error (Megalodon.jp): We can not obtain this page because the time limit has been reached or for technical ... ",
        "http://www.webcitation.org/72rbKsX8B"
      ]
    }

Example 8

Because an API Key is required by Perma.cc, the HTTP request should be as follows:

$ curl -i http://127.0.0.1:12345/all/https://nypost.com/?cc_api_key=$Your-Perma-CC-API-Key

Or use only Perma.cc:

$ curl -i http://127.0.0.1:12345/cc/https://nypost.com/?cc_api_key=$Your-Perma-CC-API-Key

Running as a Docker Container

$ docker image pull oduwsdl/archivenow

Configuring a new archive or removing existing one

Additional archives may be added by creating a handler file in the “handlers” directory.

For example, if I want to add a new archive named “My Archive”, I would create a file “ma_handler.py” and store it in the folder “handlers”. The “ma” will be the archive identifier, so to push a web page (e.g., www.cnn.com) to this archive through the Python code, I should write:

archivenow.push("www.cnn.com","ma")

In the file “ma_handler.py”, the name of the class must be “MA_handler”. This class must have at least one function called “push” which has one argument. See the existing handler files for examples on how to organized a newly configured archive handler.

Removing an archive can be done by one of the following options:

  • Removing the archive handler file from the folder “handlers”
  • Renaming the archive handler file to other name that does not end with “_handler.py”
  • Setting the variable “enabled” to “False” inside the handler file

Notes

The Internet Archive (IA) sets a time gap of at least two minutes between creating different copies of the “same” resource.

For example, if you send a request to IA to capture (www.cnn.com) at 10:00pm, IA will create a new copy (C) of this URI. IA will then return C for all requests to the archive for this URI received until 10:02pm. Using this same submission procedure for Archive.is requires a time gap of five minutes.
