hello.py

# hello.py

def application(environ, start_response):
    start_response(\'200 OK\', [(\'Content-Type\', \'text/html\')])
    return [b\'<h1>Hello, web!</h1>\']

def application2(environ, start_response):
    start_response(\'200 OK\', [(\'Content-Type\', \'text/html\')])
    body = \'<h1>Hello, %s!</h1>\' % (environ[\'PATH_INFO\'][1:] or \'web\')
    return [body.encode(\'utf-8\')]

server.py

# server.py
# 从wsgiref模块导入:
from wsgiref.simple_server import make_server
# 导入我们自己编写的application函数:
from hello import application

# 创建一个服务器，IP地址为空，端口是8000，处理函数是application:
httpd = make_server(\'\', 8000, application)
print(\'Serving HTTP on port 8000...\')
# 开始监听HTTP请求:
httpd.serve_forever()
