基于tcp实现远程执行命令

命令执行服务器：

 # Author : Kelvin
 # Date : 2019/1/30 20:10
 from socket import *
 import subprocess

 ip_conf = ("127.0.0.1", 8888)
 buffer_capacity = 1024
 tcp_server = socket(AF_INET, SOCK_STREAM)
 tcp_server.bind(ip_conf)
 tcp_server.listen(5)
 while True:
     conn, addr = tcp_server.accept()
     while True:
         try:
             cmd = conn.recv(buffer_capacity) #如果强制断开连接会触发try，try正是解决强制中断连接的问题
             print("收到的cmd：%s"%cmd)
             if not cmd: #如果使用quit断开连接，服务器会死循环收到空，该判断正是解决此问题
                 break
             res = subprocess.Popen(cmd.decode("utf8"), shell=True, stdout=subprocess.PIPE, stdin=subprocess.PIPE,
                                    stderr=subprocess.PIPE)
             err = res.stderr.read()
             if err:
                 back_msg = err
             else:
                 back_msg = res.stdout.read()
             conn.send(back_msg)
         except Exception as e:
             print(e)
             break
 tcp_server.close()

客户端：

 # Author : Kelvin
 # Date : 2019/1/30 20:10
 from socket import *

 ip_conf = ("127.0.0.1", 8888)
 buffer_capacity = 1024
 tcp_client = socket(AF_INET, SOCK_STREAM)
 tcp_client.connect(ip_conf)
 while True:
     cmd = input("Please input cmd : ")
     if not cmd:
         continue
     if cmd == "quit":
         break
     tcp_client.send(cmd.encode("utf8"))
     back_msg = tcp_client.recv(buffer_capacity).decode("gbk")
     print(back_msg)
 tcp_client.close()

执行结果：
