aiohttp 0.14.4

http client/server for asyncio

http client/server for asyncio

Features

  • Supports both client and server side of HTTP protocol.
  • Supports 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

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

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.

There 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 init(loop):
    app = web.Application(loop=loop)
    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()

CHANGES

0.14.4 (01-29-2015)

  • Fix issue with error during constructing of url with regex parts #264

0.14.3 (01-28-2015)

  • Use path=’/’ by default for cookies #261

0.14.2 (01-23-2015)

  • Connections leak in BaseConnector #253
  • Do not swallow websocket reader exceptions #255
  • web.Request’s read, text, json are memorized #250

0.14.1 (01-15-2015)

  • HttpMessage._add_default_headers does not overwrite existing headers #216
  • Expose multidict classes at package level
  • add aiohttp.web.WebSocketResponse
  • According to RFC 6455 websocket subprotocol preference order is provided by client, not by server
  • websocket’s ping and pong accept optional message parameter
  • multidict views do not accept getall parameter anymore, it returns the full body anyway.
  • multidicts have optional Cython optimization, cythonized version of multidicts is about 5 times faster than pure Python.
  • multidict.getall() returns list, not tuple.
  • Backward imcompatible change: now there are two mutable multidicts (MultiDict, CIMultiDict) and two immutable multidict proxies (MultiDictProxy and CIMultiDictProxy). Previous edition of multidicts was not a part of public API BTW.
  • Router refactoring to push Not Allowed and Not Found in middleware processing
  • Convert ConnectionError to aiohttp.DisconnectedError and don’t eat ConnectionError exceptions from web handlers.
  • Remove hop headers from Response class, wsgi response still uses hop headers.
  • Allow to send raw chunked encoded response.
  • Allow to encode output bytes stream into chunked encoding.
  • Allow to compress output bytes stream with deflate encoding.
  • Server has 75 seconds keepalive timeout now, was non-keepalive by default.
  • Application doesn’t accept **kwargs anymore (#243).
  • Request is inherited from dict now for making per-request storage to middlewares (#242).
