服务器端

import socket
import os

server = socket.socket()
server.bind(( ‘127.0.0.1‘,9999 ))

server.listen() #设置最大连接数

while True:
conn, addr = server.accept()

while True:
data = conn.recv(1024)

if not data:
print(‘客户端已断开‘)
break

cmd_res = os.popen( ( data.decode() ) ).read() #执行系统cmd命令
cmd_res = cmd_res.encode(‘utf-8‘) #执行结果编码

conn.send( str(len(cmd_res)).encode(‘utf-8‘) ) #编码后执行结果内容长度

conn.recv(1024) #解决linux系统粘包问题

conn.send(cmd_res)

server.close()

客户端

import socket

client = socket.socket()
client.connect((‘127.0.0.1‘,9999))

while True:
cmd = input(‘>>:‘).scrip()
if len(cmd) == 0: continue

client.send(cmd.encode(‘utf-8‘)) #发送信息，进行编码

cmd_res_size = client.recv(1024)
cmd_res_size = cmd_res_size.decode()
cmd_res_size = int( cmd_res_size )

received_size = 0

client.send(‘已经准备好接受数据了‘.encode(‘utf-8‘)) #随便发送数据，解决linux系统粘包问题

while received_size < cmd_res_size:
data = client.recv(1024)
received_size += len(data)

data = data.decode()

print(data)

client.close()
