python 编写Web App骨架

因为咱们的Web App创建在asyncio的基础上，所以用aiohttp写一个基本的app.py：

import logging; logging.basicConfig(level=logging.INFO) import asyncio, os, json, time from datetime import datetime from aiohttp import web def index(request): return web.Response(body=b'<h1>Awesome</h1>') @asyncio.coroutine def init(loop): app = web.Application(loop=loop) app.router.add_route('GET', '/', index) srv = yield from loop.create_server(app.make_handler(), '127.0.0.1', 9000) logging.info('server started at http://127.0.0.1:9000...') return srv loop = asyncio.get_event_loop() loop.run_until_complete(init(loop)) loop.run_forever() 

运行python app.py，Web App将在9000端口监听HTTP请求，而且对首页/进行响应：

$ python3 app.py
INFO:root:server started at http://127.0.0.1:9000... 

这里咱们简单地返回一个Awesome字符串，在浏览器中能够看到效果：

这说明咱们的Web App骨架已经搭好了，能够进一步往里面添加更多的东西。
