腾讯云ecs服务器实现socket

import socket

def start_server():
    server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    server_socket.bind(('0.0.0.0', 12345))
    server_socket.listen(5)
    print("Server listening on port 12345")

    while True:
        client_socket, addr = server_socket.accept()
        print(f"Connection from {addr}")
        data = client_socket.recv(1024)
        if data:
            print(f"Received: {data.decode('utf-8')}")
            client_socket.sendall(b"Message received")
        client_socket.close()

if __name__ == "__main__":
    start_server()

import socket

def start_client():
    client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    client_socket.connect(('服务器公网IP', 12345))
    client_socket.sendall(b"Hello, Server!")
    response = client_socket.recv(1024)
    print(f"Server response: {response.decode('utf-8')}")
    client_socket.close()

if __name__ == "__main__":
    start_client()
