python:socket通信

socket_server_ssh.py编码如下：

import socket,os server=socket.socket() server.bind(("localhost",9999)) server.listen() while True: ---conn,addr=server.accept() #等电话 ---print("new connet。。。",addr) ---while True: ---print("等待新指令....") ---data=conn.recv(1024) ---if not data: ------print("客户端已断开") ------break ---cmd_res=os.popen(data.decode()).read() #接受字符串，执行结果也是字符串 ---if len(cmd_res)==0: ------print("cmd_res has not output。。。") ---conn.send((str(len(cmd_res.encode())).encode("utf-8")) ---conn.send(cmd_res.encode("utf-8")) server.close()

socket_server_client.py编码如下： import socket client=socket.socket() client.connect(("localhost",9999)) while True: ---data=input("请输入指令：").strip() ---if len(data)==0: ------continue ---client.send(data.encode("utf-8")) ---cmd_res_size=client.recv(1024) #先接受大小 ---recevied_size=0 ---recevied_data=b'' ---while recevide_size<int(len(cmd_res_size.decode())): ------data=client.recv(1024) ------recevied_size+=len(data) #每次接收的大小不一样，所以需要用len判断一下 ------recevied_data+=data ---else: ------print("cmd_res has recevied done......") ------print(recevied_data.decode()) client.close()
