以下是支持高并发的 Linux TCP 客户端和服务端相互通讯收发数据的示例代码，并且会在代码中打印 IP 和端口等信息。 ### 服务端代码（`server.py`） ```python import socket import threading def handle_client(client_socket, client_address): print(f"Accepted connection from {client_address[0]}:{client_address[1]}") try: while True: data = client_socket.recv(1024) if not data: break print(f"Received from {client_address[0]}:{client_address[1]}: {data.decode('utf-8')}") client_socket.sendall(f"Server received: {data.decode('utf-8')}".encode('utf-8')) except Exception as e: print(f"Error handling client {client_address}: {e}") finally: client_socket.close() print(f"Connection closed with {client_address[0]}:{client_address[1]}") def main(): server = socket.socket(socket.AF_INET, socket.SOCK_STREAM) server.bind(('0.0.0.0', 8888)) server.listen(5) print("Server listening on 0.0.0.0:8888") while True: client_socket, client_address = server.accept() client_handler = threading.Thread(target=handle_client, args=(client_socket, client_address)) client_handler.start() if __name__ == "__main__": main() ``` ### 客户端代码（`client.py`） ```python import socket def main(): client = socket.socket(socket.AF_INET, socket.SOCK_STREAM) server_address = ('127.0.0.1', 8888) client.connect(server_address) print(f"Connected to server {server_address[0]}:{server_address[1]}") try: message = "Hello, server!" client.sendall(message.encode('utf-8')) response = client.recv(1024) print(f"Received from server: {response.decode('utf-8')}") except Exception as e: print(f"Error: {e}") finally: client.close() if __name__ == "__main__": main() ``` ### 代码说明 - **服务端**：使用 Python 的 `socket` 模块创建一个 TCP 套接字，绑定到 `0.0.0.0:8888` 地址并开始监听。每当有新的客户端连接时，会创建一个新的线程来处理该客户端的请求，这样可以实现高并发处理。 - **客户端**：同样使用 `socket` 模块创建一个 TCP 套接字，连接到服务端的 `127.0.0.1:8888` 地址，发送一条消息并接收服务端的响应。 ### 运行方法 1. 首先运行服务端代码：`python server.py` 2. 然后运行客户端代码：`python client.py`
