Python之tcp server模拟Http通信

1.python tcp server代码：

 import socket

 def main():
     tcp_server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
     tcp_server_socket.bind(('', 6699))
     tcp_server_socket.listen(128)

     while True:
         new_client_socket, new_client_addr = tcp_server_socket.accept()
         # 接收浏览器请求
         request = new_client_socket.recv(1024)
         print(request)

         # 响应浏览器请求
         # 为了兼容所有的浏览器约定浏览器中的换行为\r\n
         respond = 'GET HTTP/1.1\r\n'
         respond += '\r\n'
         respond += '<h2>Hello Python</h2>'
         new_client_socket.send(respond.encode('utf=8'))
         new_client_socket.close()

     tcp_server_socket.close()

 if __name__ == '__main__':
     main()

终端显示：
