执行WinSCP脚本时，subprocess.Popen中的Python双引号不起作用

问题描述

我正在尝试使用此处的代码 https://stackoverflow.com/a/56454579 将文件上传到Windows 10上使用来自Python的WinSCP服务器.代码如下:

I am attempting to use the code from here https://stackoverflow.com/a/56454579 to upload files to a server with WinSCP from Python on Windows 10. The code looks like this:

import subprocess
path = r'C:\mp4s\Sci-Fi Light Flicker.mp4'

process = subprocess.Popen(
  ['C:\Program Files (x86)\WinSCP\WinSCP.com', '/ini=nul', '/command', 'option batch abort', 'option confirm off', 'open ftp://user:[email protected]', f'put "{path}"', 'exit'],
  stdout=subprocess.PIPE, stderr=subprocess.PIPE)
for line in iter(process.stdout.readline, b''):
  print(line.decode().rstrip())

我得到输出:

batch           abort
confirm         off
Connecting to ftp.website.com ...
Connected
Starting the session...
Session started.
Active session: [1] [email protected]
File or folder '\C:\mp4s\Sci-Fi' does not exist.
System Error.  Code: 123.
The filename, directory name, or volume label syntax is incorrect
(A)bort, (R)etry, (S)kip, Ski(p) all: Abort

告诉我 put 命令不能正确处理文件名中的空格.我需要进行哪些更改才能使其正常工作?删除路径周围的双引号会给我一个不同的错误(它认为我正在尝试上传多个文件).

Which tells me that the put command isn't properly handling the spaces in the filename. What do I need to change to get this to work? Removing the double quotes around the path gives me a different error (it thinks I'm trying to upload multiple files).

推荐答案

我认为您不能使用数组为WinSCP提供参数. subprocess.Popen 转义使用反斜杠在参数中使用双引号，则与转义双双引号发生冲突WinSCP.

I do not think you can use an array to provide arguments to WinSCP. The subprocess.Popen escapes double quotes in the arguments using backslash, what conflicts with double double-quotes escaping expected by WinSCP.

您将必须自行格式化WinSCP命令行:

You will have to format the WinSCP command-line on your own:

args =  "\"C:\Program Files (x86)\WinSCP\WinSCP.com\" /ini=nul " + \
       f"/command \"open ftp://user:[email protected]\" \"put \"\"{path}\"\"\" exit"

(请注意，我已经省略了 option 命令，因为它们还是默认值)

(note that I've omitted your option commands, as they are defaults anyway)
