aiohttpasyncio 的 HTTP 客户端/服务端
aiohttp 是 asyncio 的 HTTP 客户端/服务端。
特性
-
Web-server 有中间件和可插拔路由
服务器端简单使用示例：
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()评论
