与TCP服务器上的客户端进行多数据交换

以下是一个示例代码，展示了如何在TCP服务器上与客户端进行多数据交换。该示例使用Python的socket库来实现TCP服务器和客户端。

TCP服务器端代码：

import socket

def handle_client(client_socket):
    while True:
        # 接收客户端发送的数据
        data = client_socket.recv(1024)
        if not data:
            break
        print("Received data from client:", data.decode())

        # 向客户端发送数据
        response = "Server received your data: " + data.decode()
        client_socket.sendall(response.encode())

    # 关闭客户端连接
    client_socket.close()

def start_server():
    # 创建TCP套接字
    server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

    # 绑定服务器地址和端口
    server_address = ('localhost', 8888)
    server_socket.bind(server_address)

    # 监听客户端连接
    server_socket.listen(1)

    print("Server is listening on", server_address)

    while True:
        # 等待客户端连接
        print("Waiting for a client to connect...")
        client_socket, client_address = server_socket.accept()
        print("Client connected from", client_address)

        # 处理客户端请求
        handle_client(client_socket)

    # 关闭服务器套接字
    server_socket.close()

start_server()

TCP客户端代码：

import socket

def start_client():
    # 创建TCP套接字
    client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

    # 连接服务器
    server_address = ('localhost', 8888)
    client_socket.connect(server_address)

    while True:
        # 从用户输入中获取数据
        data = input("Enter data to send to server (or type 'exit' to quit): ")
        if data == 'exit':
            break

        # 向服务器发送数据
        client_socket.sendall(data.encode())

        # 接收服务器的响应
        response = client_socket.recv(1024)
        print("Received response from server:", response.decode())

    # 关闭客户端套接字
    client_socket.close()

start_client()

使用上述代码，您可以运行服务器端代码来启动TCP服务器，然后运行客户端代码来连接到服务器并进行多数据交换。
