Python启动TCP服务并监听连接，从客户端发送消息
|
下面是一个简单的例子，演示如何在Python中启动TCP服务并监听连接，以及如何从客户端发送消息： TCP服务端代码： import socket HOST = '192.168.6.211' PORT = 8888 server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) server_socket.bind((HOST, PORT)) server_socket.listen() print(f'Server is listening at {HOST}:{PORT}') while True: client_socket, client_address = server_socket.accept() print(f'Client connected from {client_address}') message = client_socket.recv(1024).decode('utf-8') print(f'Received message from client: {message}') response = 'Hello from server!' client_socket.send(response.encode('utf-8')) client_socket.close()TCP客户端代码： import socket HOST = '192.168.6.211' PORT = 8888 client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) client_socket.connect((HOST, PORT)) message = 'Hello from client!' client_socket.send(message.encode('utf-8')) response = client_socket.recv(1024).decode('utf-8') print(f'Received response from server: {response}') client_socket.close()这个例子中，服务端首先创建一个socket对象并绑定地址和端口，然后开始监听连接。当客户端连接到服务器时，服务端接受客户端的连接请求并打印客户端地址，然后接收从客户端发送过来的消息，并回复一条消息。客户端首先创建一个socket对象并连接到服务器，然后发送一条消息，并等待接收回复消息。
