这里只做一个Demo:

Step1: 定义hello.py 

def demo_app1(environ,start_response):
    from io import StringIO
    stdout = StringIO()
    print("Hello world!", file=stdout)
    print(file=stdout)
    h = sorted(environ.items())
    for k,v in h:
        print(k,'=',repr(v), file=stdout)
    start_response("200 OK", [('Content-Type','text/plain; charset=utf-8')])
    return [stdout.getvalue().encode("utf-8")]

Step2:在同目录下，定义server.py

# 从wsgiref模块导入:
from wsgiref.simple_server import make_server, demo_app
from LXF.Web开发.hello import demo_app1

application = demo_app1

# 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('127.0.0.1', 8000, application)
print("Serving HTTP on port 8000...")

httpd.handle_request()

Step3: 运行sever.py，　在浏览器中输入 localhost:8000
