http client/server for asyncio
Project description
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.
Getting started
Client
To retrieve something from the web:
import aiohttp
import asyncio
async def fetch(session, url):
with aiohttp.Timeout(10):
async with session.get(url) as response:
return await response.text()
if __name__ == '__main__':
loop = asyncio.get_event_loop()
with aiohttp.ClientSession(loop=loop) as session:
html = loop.run_until_complete(
fetch(session, 'http://python.org'))
print(html)
Server
This is simple usage example:
from aiohttp import web
async def handle(request):
name = request.match_info.get('name', "Anonymous")
text = "Hello, " + name
return web.Response(body=text.encode('utf-8'))
async def wshandler(request):
ws = web.WebSocketResponse()
await ws.prepare(request)
async for msg in ws:
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
app = web.Application()
app.router.add_route('GET', '/echo', wshandler)
app.router.add_route('GET', '/{name}', handle)
web.run_app(app)
Note: examples are written for Python 3.5+ and utilize PEP-492 aka async/await. If you are using Python 3.4 please replace await with yield from and async def with @coroutine e.g.:
async def coro(...): ret = await f()
shoud be replaced by:
@asyncio.coroutine def coro(...): ret = yield from f()
