CozyWeboob

This is an attempt at using Weboob as a Cozy Konnector. It wraps around Weboob, receiving a JSON description of the modules to fetch on stdin and returning a JSON of the fetched results on stdout.

Although the primary goal is to wrap around Weboob to use it in Cozy, this script might be of interest for anyone willing to wrap around Weboob and communicate with JSON pipes.

Usage

First, you need to have Weboob installed on your system.

Cozyweboob script

Typical command-line usage for this script is:

cat konnectors.json | ./cozyweboob.py

where konnectors.json is a valid JSON file defining konnectors to be used.

Server script

Typical command-line usage for this script is:

./server.py

This script spawns a Bottle webserver, listening on localhost:8080 (by default).

It has a single route, the index route, which supports POST method to send a valid JSON string defining konnectors to be used in a params field. Typical example to send it some content is:

curl -X POST --data "params=$(cat konnectors.json)" "http://localhost:8080/"

where konnectors.json is a valid JSON file defining konnectors to be used.

Note: You can specify the host and port to listen on using the COZYWEBOOB_HOST and COZYWEBOOB_PORT environment variables.

Notes concerning all the available scripts

Using COZYWEBOOB_ENV=debug, you can enable debug features for all of these scripts, which might be useful for development. These features are:

  • Logging
  • If you pass a blank field in a JSON konnector description (typically password: ""), the script will ask you its value at runtime, using getpass.

Input JSON file

The JSON file read on stdin should have a specific structure. A typical example is given in konnectors.json.sample.

Basically, it consists of a list of maps. Each map corresponds to a given Weboob module to run, with a given set of parameters (then allowing the script to run multiple times the same module with different configurations). Each map should have at the following three keys:

  • name is the name of the Weboob module to run (same name as used in Weboob).
  • parameters is a map of parameters to use for this particular module, as required by the associated Weboob backend.
  • id should be a unique string of your choice, to uniquely identify this run of the specified module with the specified set of parameters.

Output JSON file

The resulting JSON file, on stdout is a map associating the id fields as provided in input JSON file to a map of fetched data by this module.

Each module map has a cookies entry containing the cookies used to fetch the data, so that any program running afterwards can download documents.

Important note: Most of such websites have very short lived sessions, meaning in most cases these cookies will be useless for extra download as the session will most likely be destroyed on the server side.

The other entries in these maps depend on the module capabilities as defined by Weboob. Detailed informations about these other entires can be found in the doc/capabilities folder.

Contributing

All contributions are welcome. Feel free to make a PR :)

Python code is currently Python 2, but should be Python 3 compatible as Weboob is moving towards Python 3. All Python code should be PEP8 compliant. I use some extra rules, taken from PyLint.
