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, loop=session.loop):
async with session.get(url) as response:
return await response.text()
async def main(loop):
async with aiohttp.ClientSession(loop=loop) as session:
html = await fetch(session, 'http://python.org')
print(html)
if __name__ == '__main__':
loop = asyncio.get_event_loop()
loop.run_until_complete(main(loop))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(text=text)
async def wshandler(request):
ws = web.WebSocketResponse()
await ws.prepare(request)
async for msg in ws:
if msg.type == web.MsgType.text:
ws.send_str("Hello, {}".format(msg.data))
elif msg.type == web.MsgType.binary:
ws.send_bytes(msg.data)
elif msg.type == web.MsgType.close:
break
return ws
app = web.Application()
app.router.add_get('/echo', wshandler)
app.router.add_get('/', handle)
app.router.add_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()
should be replaced by:
@asyncio.coroutine
def coro(...):
ret = yield from f()

CHANGES
1.1.3 (2016-11-10)
Support root resources for sub-applications #1379
1.1.2 (2016-11-08)
Allow starting variables with an underscore #1379
Properly process UNIX sockets by gunicorn worker #1375
Fix ordering for FrozenList
Don’t propagate pre and post signals to sub-application #1377
1.1.1 (2016-11-04)
Fix documentation generation #1120
1.1.0 (2016-11-03)
Drop deprecated WSClientDisconnectedError (BACKWARD INCOMPATIBLE)
Use yarl.URL in client API. The change is 99% backward compatible but ClientResponse.url is an yarl.URL instance now. #1217
Close idle keep-alive connections on shutdown #1222
Modify regex in AccessLogger to accept underscore and numbers #1225
Use yarl.URL in web server API. web.Request.rel_url and web.Request.url are added. URLs and templates are percent-encoded now. #1224
Accept yarl.URL by server redirections #1278
Return yarl.URL by .make_url() testing utility #1279
Properly format IPv6 addresses by aiohttp.web.run_app #1139
Use yarl.URL by server API #1288
Introduce resource.url_for(), deprecate resource.url().
Implement StaticResource.
Inherit SystemRoute from AbstractRoute
Drop old-style routes: Route, PlainRoute, DynamicRoute, StaticRoute, ResourceAdapter.
Revert resp.url back to str, introduce resp.url_obj #1292
Raise ValueError if BasicAuth login has a “:” character #1307
Fix bug when ClientRequest send payload file with opened as open(‘filename’, ‘r+b’) #1306
Enhancement to AccessLogger (pass extra dict) #1303
Show more verbose message on import errors #1319
Added save and load functionality for CookieJar #1219
Added option on StaticRoute to follow symlinks #1299
Force encoding of application/json content type to utf-8 #1339
Fix invalid invocations of errors.LineTooLong #1335
Websockets: Stop async for iteration when connection is closed #1144
Ensure TestClient HTTP methods return a context manager #1318
Raise ClientDisconnectedError to FlowControlStreamReader read function if ClientSession object is closed by client when reading data. #1323
Document deployment without Gunicorn #1120
Add deprecation warning for MD5 and SHA1 digests when used for fingerprint of site certs in TCPConnector. #1186
Implement sub-applications #1301
Don’t inherit web.Request from dict but implement MutableMapping protocol.
Implement frozen signals
Don’t inherit web.Application from dict but implement MutableMapping protocol.
Support freezing for web applications
Accept access_log parameter in web.run_app, use None to disable logging
Don’t flap tcp_cork and tcp_nodelay in regular request handling. tcp_nodelay is still enabled by default.
Improve performance of web server by removing premature computing of Content-Type if the value was set by web.Response constructor.
While the patch boosts speed of trivial web.Response(text=’OK’, content_type=’text/plain) very well please don’t expect significant boost of your application – a couple DB requests and business logic is still the main bottleneck.
Boost performance by adding a custom time service #1350
Extend ClientResponse with content_type and charset properties like in web.Request. #1349
Disable aiodns by default #559
Don’t flap tcp_cork in client code, use TCP_NODELAY mode by default.
Implement web.Request.clone() #1361
