编写Web App骨架

创建一个 request handle 创建一个Application实例并对request handler注册 创建服务器，绑定地址，端口，和handler

代码

import logging; logging.basicConfig(level=logging.INFO)
import asyncio, os, json, time
from datetime import datetime
from aiohttp import web

def index(request): #创建一个request handler
    return web.Response(body=b'

Awesome

') @asyncio.coroutine def init(loop): #初始化服务器 app = web.Application(loop=loop) #创建一个Application实例 app.router.add_route('GET', '/', index) #用实例对request handler注册 srv = yield from loop.create_server(app.make_handler(), '127.0.0.1', 9000) #创建服务器，绑定地址，端口和handler logging.info('server started at https://127.0.0.1:9000...') return srv loop = asyncio.get_event_loop() #获取EventLoop loop.run_until_complete(init(loop)) #执行协程 loop.run_forever() #服务器不关闭
