linux+python实现tcp

下面是一个基本的Python TCP服务器和客户端示例：

服务器端：

import socket

# 创建TCP socket对象
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

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

# 监听连接
server_socket.listen()

print('Server is listening on port 8888...')

while True:
    # 接受连接请求
    client_socket, address = server_socket.accept()

    print(f'New connection from {address}')

    # 接受客户端发送的消息
    message = client_socket.recv(1024)

    print(f'Received message from client: {message.decode()}')

    # 发送响应消息给客户端
    response = 'Hello from server!'
    client_socket.send(response.encode())

    # 关闭连接
    client_socket.close()

客户端：

import socket

# 创建TCP socket对象
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

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

# 发送消息给服务器
message = 'Hello from client!'
client_socket.send(message.encode())

# 接受服务器发送的响应消息
response = client_socket.recv(1024)

print(f'Received message from server: {response.decode()}')

# 关闭连接
client_socket.close()
