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()
