receive 0.1.1

Host a temporary HTTP server to receive a web-hook callback.

Receive

receive is a python library for hosting temporary web servers and receiving values from their route handlers via futures.

Install

Stable Release

pip install receive

Latest Features

pip install git+https://github.com/BlakeASmith/receive

Usage

Handle a GET request

First, define a route handler as follows:

import receive

@receive.get_request(route="/callback", port=5000)
async def get_query_param_from_request(req):
    return req.query["code"]

The req parameter is an aiohttp.web.Request object. In this example we return the code query parameter from the request.

Now we can start a temporary web server, and get our return value from the first request that comes in.

import asyncio

async def main():
    future = await get_query_param_from_request()
    code = await future
    print(code)
    
    
if __name__ == "__main__":
    asyncio.get_event_loop().run_until_complete(main)

The get_query_param_from_request function will start a web server in the background and return a asyncio.Future object providing access to the return value from the handler. get_query_param_from_request will return immediately, and invoking await on the returned future will block until a GET 0.0.0.0:5000/callback request hits the server. At that time the future will be completed with the value returned from the request handler and the server will be shutdown.

Tests
