**http协议是基于tcp的，所以利用tcp可以实现http协议，实现一个简单的 http web server功能。**

import socketserver

body = """<h1>hello web client</h1>"""

response_param = ['HTTP/1.0 200 OK',

'Date: Mon, 13 May 2019 09:57:18 GMT',

'Content-Type: text/html; charset=utf-8',

'Content-Length: {}\r\n'.format(len(body.encode())),

body]

response = '\r\n'.join(response_param)

class MyServer(socketserver.BaseRequestHandler):

def handle(self):

conn = self.request

recv_data = b''

while b'\n\n' not in recv_data and b'\n\r\n' not in recv_data:

recv_data += conn.recv(1024)

print(recv_data)

conn.send(response.encode())

conn.close()

if __name__ == '__main__':

# 第一步

# 实例化server对象，传入本机ip，以及监听的端口号，还有新建的继承socketserver模块下的BaseRequestHandler类

server = socketserver.ThreadingTCPServer(('127.0.0.1', 8000), MyServer)

# 激活服务端

server.serve_forever()
