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

        respond = 'GET HTTP/1.1
'
        respond += '
'
        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：
