# Webhook Listener
Very basic webserver module to listen for webhooks and forward requests to predefined functions.

https://pypi.org/project/webhook_listener/

https://github.com/toddrob99/Webhooks

## Install

Install from PyPI using pip

`pip install webhook_listener`

## Use

* Define a function to process requests
    * `request` parameter will be a cherrypy request object
    * `*args` parameter will be a tuple of URL path components
    * `**kwargs` parameter will be a dictionary of URL parameters
    * Get the body of a `POST` request from `request.body.read` passing the length of `request.headers['Content-Length']`: `request.body.read(int(request.headers['Content-Length'])) if int(request.headers.get('Content-Length',0)) > 0 else ''`
    * Note: The body will be a byte array, and not a string. You may need to decode it to a string. For example:
        ```
        import json
        body_raw = request.body.read(int(request.headers['Content-Length'])) if int(request.headers.get('Content-Length',0)) > 0 else '{}'
        body = json.loads(body_raw.decode('utf-8'))
        ```
* Include webhook-listener in your project
* Create an instance of the webhook_listener.Listener class
    * handlers = Dictionary of functions/callables for each supported HTTP method. (Example: {'POST':process_post_request, 'GET':process_get_request})
    * port = Port for the web server to listen on (default: 8090)
    * host = Host for the web server to listen on (default: '0.0.0.0')
    * threadPool = Number of worker threads for the web server (default: 10)
    * logScreen = Setting for cherrypy to log to screen (default: False)
    * autoReload = Setting for cherrypy to auto reload when python files are changed (default: False)
    * sslModule = Select which SSL library to use (default: 'builtin')
    * sslCert = Path to the certificate (SSL is disabled when empty)
    * sslPrivKey = Path to the certificate's private key (SSL is disabled when empty)
    * sslCertChain = Path to the full certificate chain
      see https://cherrypydocrework.readthedocs.io/deploy.html#ssl-support for more information on SSL support
* Start the Listener
* Keep your application running so the Listener can run in a separate thread

## Example

    import time
    import webhook_listener


    def process_post_request(request, *args, **kwargs):
        print(
            "Received request:\n"
            + "Method: {}\n".format(request.method)
            + "Headers: {}\n".format(request.headers)
            + "Args (url path): {}\n".format(args)
            + "Keyword Args (url parameters): {}\n".format(kwargs)
            + "Body: {}".format(
                request.body.read(int(request.headers["Content-Length"]))
                if int(request.headers.get("Content-Length", 0)) > 0
                else ""
            )
        )

        # Process the request!
        # ...

        return


    webhooks = webhook_listener.Listener(handlers={"POST": process_post_request})
    webhooks.start()

    while True:
        print("Still alive...")
        time.sleep(300)
