python,socket通信编程小例子,客户端发送命令到服务端,并返回运行结果

server.py程序
import socket,subprocess
sk = socket.socket()
address = (‘127.0.0.1‘,8001)
sk.bind(address)
sk.listen(3)
conn,addr = sk.accept()
data = conn.recv(1024)
obj = subprocess.Popen(str(data,‘utf8‘),shell=True,stdout=subprocess.PIPE)
cmd_result = obj.stdout.read()
conn.sendall(cmd_result)
sk.close()

client.py程序
import socket
sk = socket.socket()
address = (‘127.0.0.1‘,8001)
sk.connect(address)
data = input(‘>>>‘)
sk.send(bytes(data,‘utf8‘))
result = sk.recv(1024)
print(str(result,‘utf8‘))
sk.close()
