Ubuntu启一个tcp server，client去连接

1、在~/source/code/python目录下创建两个py文件：

server_8079.py、client_8079.py

server_8079.py的代码：

# server.py import socket def start_server(host, port): # 创建一个TCP/IP套接字 server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # 绑定套接字到地址和端口 server_socket.bind((host, port)) # 监听传入连接 server_socket.listen(1) print(f"Server listening on {host}:{port}") while True: # 等待连接 client_socket, addr = server_socket.accept() try: print(f"Connection from {addr}") # 接收数据 data = client_socket.recv(1024) print(f"Received: {data.decode('utf-8')}") # 发送响应 response = "Hello from server!" client_socket.sendall(response.encode('utf-8')) finally: # 清理连接 client_socket.close() if __name__ == "__main__": HOST = '192.168.111.128' PORT = 8079 start_server(HOST, PORT)

client_8079.py的代码：

# client.py import socket def start_client(host, port): # 创建一个TCP/IP套接字 client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) try: # 连接到服务器 client_socket.connect((host, port)) # 发送数据 message = "Hello from client!" client_socket.sendall(message.encode('utf-8')) # 接收响应 response = client_socket.recv(1024) print(f"Received: {response.decode('utf-8')}") finally: # 清理连接 client_socket.close() if __name__ == "__main__": HOST = '192.168.111.128' PORT = 8079 start_client(HOST, PORT)

打开2个terminal：

在第1个terminal输入：

python3 server_8079.py

在第2个terminal输入：

python3 client_8079.py
