tcp回显客户端发送的数据

客户端:

import socket

tcp_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
tcp_socket.connect(('127.0.0.1', 12345))
while True:
    tcp_socket.send(input('你输入要回显的数据:').encode())
    print('回显数据:', tcp_socket.recv(1024).decode())

服务端：

import socket

tcp_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
tcp_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
tcp_socket.bind(('',12345))
tcp_socket.listen(128)
tcp_server, client_addr = tcp_socket.accept()
while True:
    print(client_addr, '连接成功')
    serve_recv = tcp_server.recv(1024)
    tcp_server.send(serve_recv)
