1、客户端

import socketdef main():tcp_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)server_ip = input("请输入要连接的服务器的ip:")server_port = int(input("请输入要连接的服务器的port:"))server_addr = (server_ip, server_port)tcp_socket.connect(server_addr)send_data = input("请输入要发送的数据:")tcp_socket.send(send_data.encode("utf-8"))tcp_socket.close()if __name__ == "__main__":main()

2、服务器

import socketdef main():tcp_sever_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)tcp_sever_socket.bind(("", 7890))tcp_sever_socket.listen(128)while True:print("等待一个新的客户端的到来")new_client_socket, client_addr = tcp_sever_socket.accept()print("一个新的客户端已经到来%s" % str(client_addr))while True:recv_data = new_client_socket.recv(1024)print("客户端发送过来的请求是:%s" % recv_data.decode("utf-8"))if recv_data:new_client_socket.send("hahahaha".encode("utf-8"))else:breaknew_client_socket.close()print("已经为这个客户端服务完毕")tcp_sever_socket.close()if __name__ == "__main__":main()
