通过套接字在目录中列出文件Python

Question

如何发送命令以通过套接字列出目录中的文件？

#
# Write a script that connects to 'localhost' port 10000
# You then need to send a command to list the files in the /tmp directory
#

import socket, os, json

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(("localhost", 10000))
cmd = json.dumps(os.listdir("/tmp"))
sock.send(cmd.encode())
print(sock.recv(1024).decode())

它完全没有输出！有什么用？

我有点不喜欢回答自己的问题，但是找到了答案。我这样使用subprocess.Popen：

import socket, subprocess
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(("localhost", 10000))
cmd = ["ls", "-a", "/tmp"]
order = subprocess.Popen(cmd)
sock.send(order)
print(sock.recv(1024))

仍然感谢您的帮助！
