WSGI Server（uwsgi原理）

WSGI Server

server.py

from wsgiref.simple_server import make_server
from app import application

httpd = make_server('0.0.0.0', 8080, application)
print('start http server 8080...')

httpd.serve_forever()

app.py

def application(environ, start_response):
    start_response('200 OK', [('Content-Type', 'text/html')])
    print(environ['PATH_INFO'])
    body = '<h1>Hello, %s!</h1>' % (environ['PATH_INFO'][1:] or 'web')
    return [body.encode('utf-8')]

好了，打开浏览器，输入127.0.0.1:8080/helloworld/

注意，server.py运行时可能会卡住，可以反复运行一次，浏览器就能访问到了
