Python实战-编写Web App-Day2-编写Web App骨架

我们的webapp基于aiohttp建立，写一个简单的app.py把网络环境先运行起来：

# -*- coding: UTF-8 -*-
# Filename : app.py
# author by : woodmanzhang.com


import logging;logging.basicConfig(level=logging.INFO)

import asyncio,os,json,time
from datetime import datetime

from aiohttp import web,web_runner


routes = web.RouteTableDef()


@routes.get('/')
def index(request):
    return web.Response(body='<h1>Go!WoodmanZhang!</h1>', content_type='text/html')


def init():
    app = web.Application()
    app.add_routes([web.get('/', index)])
    logging.info('server started at http://127.0.0.1:9000...')
    web.run_app(app, host='127.0.0.1', port=9000)


init()

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

/usr/local/bin/python3.8 ".../first web app/conf/app.py"
INFO:root:server started at http://127.0.0.1:9000...
======== Running on http://127.0.0.1:9000 ========
(Press CTRL+C to quit)

我们直接去浏览器访问http://127.0.0.1:9000，就可以看到刚才编写的“Go!WoodmanZhang!”这段内容：

ok，骨架搭建完毕！
