TCP/IP网络通信示例代码及技术解答

本示例演示了使用Python编写的TCP/IP网络通信代码，实现简单的客户端和服务器端互相通信的功能。通过Socket库实现网络连接和数据传输，展示了TCP协议的基本应用。

# 服务器端代码
import socket

# 创建TCP/IP套接字
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 绑定IP地址和端口号
server_address = ('localhost', 8080)
server_socket.bind(server_address)

# 监听连接请求
server_socket.listen(1)

print('等待客户端连接...')
connection, client_address = server_socket.accept()

try:
    print('连接来自：', client_address)

    # 接收数据
    data = connection.recv(1024)
    print('收到消息：', data.decode('utf-8'))

    # 发送响应
    connection.sendall('服务器已收到消息'.encode('utf-8'))

finally:
    # 关闭连接
    connection.close()
    server_socket.close()


# 客户端代码
import socket

# 创建TCP/IP套接字
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 连接服务器
server_address = ('localhost', 8080)
client_socket.connect(server_address)

try:
    # 发送数据
    message = 'Hello, Server!'
    client_socket.sendall(message.encode('utf-8'))

    # 接收响应
    data = client_socket.recv(1024)
    print('收到服务器响应：', data.decode('utf-8'))

finally:
    # 关闭连接
    client_socket.close()
