基于TCP_socket套接字实现远程执行命令

#服务端import socket
import subprocess
phone=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
ip_port=("127.0.0.1",8080)
phone.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)
phone.bind(ip_port)
phone.listen(5)while True:
conn,addr=phone.accept()
print(addr)
while True:
try:
cmd=conn.recv(1024)
res=subprocess.Popen(cmd.decode("utf8"),
shell=True,
stdout=subprocess.PIPE,
stderr=subprocess.PIPE)#注释掉的这么多行，是因为在linux系统下同时执行多条命令，命令中如果有对有错的话res.stderr.read()和res.stdout.read()都会有返回值。
#err=res.stderr.read()
#if err:
# cmd_res=err
#else:
# cmd_res=res.stdout.read()
#conn.send(cmd_res)
#修改为：
conn.send(res.stdout.read())
conn.send(res.stderr.read()) except Exception:
break
conn.close()
phone.close()

#客户端import socket
phone=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
phone.connect(("192.168.85.129",8080))
while True:
cmd=input(">>:").strip()
if not cmd:continue
phone.send(cmd.encode("utf8"))
data=phone.recv(8192) #当命令行打印的东西太长时，接收超过1024，所以这里修改为8192
print(data.decode("utf8")) #当服务端运行在linux系统下，为utf8；服务端在windows下运行时，为gbkphone.close()
