aiohttp 0.16.6

http client/server for asyncio

http client/server for asyncio

Features

  • Supports both client and server side of HTTP protocol.
  • Supports both client and server Web-Sockets out-of-the-box.
  • Web-server has middlewares and pluggable routing.

Requirements

License

aiohttp is offered under the Apache 2 license.

Source code

The latest developer version is available in a github repository: https://github.com/KeepSafe/aiohttp

Getting started

Client

To retrieve something from the web:

import aiohttp
import asyncio

def get_body(url):
    response = yield from aiohttp.request('GET', url)
    return (yield from response.read())

if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    raw_html = loop.run_until_complete(get_body('http://python.org'))
    print(raw_html)

You can use the get command like this anywhere in your asyncio powered program:

response = yield from aiohttp.request('GET', 'http://python.org')
body = yield from response.read()
print(body)

If you want to use timeouts for aiohttp client side please use standard asyncio approach:

yield from asyncio.wait_for(request('GET', url), 10)

Server

In aiohttp 0.12 we’ve added highlevel API for web HTTP server.

This is simple usage example:

import asyncio
from aiohttp import web


@asyncio.coroutine
def handle(request):
    name = request.match_info.get('name', "Anonymous")
    text = "Hello, " + name
    return web.Response(body=text.encode('utf-8'))


@asyncio.coroutine
def wshandler(request):
    ws = web.WebSocketResponse()
    ws.start(request)

    while True:
        msg = yield from ws.receive()

        if msg.tp == web.MsgType.text:
            ws.send_str("Hello, {}".format(msg.data))
        elif msg.tp == web.MsgType.binary:
            ws.send_bytes(msg.data)
        elif msg.tp == web.MsgType.close:
            break

    return ws


@asyncio.coroutine
def init(loop):
    app = web.Application(loop=loop)
    app.router.add_route('GET', '/echo', wshandler)
    app.router.add_route('GET', '/{name}', handle)

    srv = yield from loop.create_server(app.make_handler(), '127.0.0.1', 8080)
    print("Server started at http://127.0.0.1:8080")
    return srv

loop = asyncio.get_event_loop()
loop.run_until_complete(init(loop))
loop.run_forever()
