Day 2 – 编写Web App骨架

最后更新于:2022-04-01 01:16:12

由于我们的Web App建立在asyncio的基础上,因此用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,并且对首页`/`进行响应: ~~~ $ python3 app.py INFO:root:server started at http://127.0.0.1:9000... ~~~ 这里我们简单地返回一个`Awesome`字符串,在浏览器中可以看到效果: ![2015-06-25/558ba18c3bcd1](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2015-06-25_558ba18c3bcd1.png) 这说明我们的Web App骨架已经搭好了,可以进一步往里面添加更多的东西。 ### 参考源码 [day-02](https://github.com/michaelliao/awesome-python3-webapp/tree/day-02)
