如何在远程主机上运行本地python脚本并使用子进程与之通信？

Question

I'm trying to write a Python program that executes a local Python script on a remote host and lets me communicate with the script when it's running.

My code currently consists of the two files run.py and remote.py :

run.py :

import os
import subprocess as sp

with open(os.path.join(os.path.dirname(__file__), "remote.py")) as scriptf:
    node_script = scriptf.read()

sess = sp.Popen(["ssh", "remote_host", "/usr/bin/python -"], stdin=sp.PIPE, stdout=sp.PIPE)
stdout, stderr = sess.communicate(node_script)
print(stdout, stderr)
sess.stdin.write("Print me this!\n")

remote.py :

import sys

print("Hello!")

while True:
    line = input()
    print(line)

This gives me the following error:

$ python run.py
Traceback (most recent call last):
  File "<stdin>", line 6, in <module>
EOFError: EOF when reading a line
('Hello!\n', None)
Traceback (most recent call last):
  File "run.py", line 10, in <module>
    sess.stdin.write("Print me this!\n")
ValueError: I/O operation on closed file

Is there any way I can pipe a python script into a remote Python interpreter like this AND be able to use something like input() on that script later? How could I change my example to work?

您可以尝试使用paramiko-sftp 链接将python脚本传输到远程系统，然后使用paramiko-ssh 链接登录到远程系统以在远程系统上运行脚本。
