Python 中用于批量复制的持久 WinSCP 连接

发布于 2024-12-17 12:34:38 字数 458 浏览 4 评论 0原文

我正在尝试将数千个文件复制到远程服务器。这些文件是在脚本内实时生成的。我正在 Windows 系统上工作，需要将文件复制到 Linux 服务器（因此需要转义）。

我目前有：

import os
os.system("winscp.exe /console /command  \"option batch on\" \"option confirm off\" \"open user:pass@host\" \"put f1.txt /remote/dest/\"")

我正在使用Python来生成文件，但需要一种方法来持久保存远程连接，以便我可以在生成每个文件时将其复制到服务器（而不是每次创建一个新连接）。这样，我只需要更改 put 选项中的字段：

"put f2 /remote/dest"
"put f3 /remote/dest"

等等。

I'm trying to copy thousands files to a remote server. These files are generated in real-time within the script. I'm working on a Windows system and need to copy the files to a Linux server (hence the escaping).

I currently have:

import os
os.system("winscp.exe /console /command  \"option batch on\" \"option confirm off\" \"open user:pass@host\" \"put f1.txt /remote/dest/\"")

I'm using Python to generate the files but need a way to persist the remote connection so that I can copy each file, to the server, as it is generated (as opposed to creating a new connection each time). That way, I'll only need to change the field in the put option thus:

"put f2 /remote/dest"
"put f3 /remote/dest"

etc.

我需要这样做，并发现与此类似的代码效果很好：

from subprocess import Popen, PIPE

WINSCP = r'c:\<path to>\winscp.com'

class UploadFailed(Exception):
    pass

def upload_files(host, user, passwd, files):
    cmds = ['option batch abort', 'option confirm off']
    cmds.append('open sftp://{user}:{passwd}@{host}/'.format(host=host, user=user, passwd=passwd))
    cmds.append('put {} ./'.format(' '.join(files)))
    cmds.append('exit\n')
    with Popen(WINSCP, stdin=PIPE, stdout=PIPE, stderr=PIPE,
               universal_newlines=True) as winscp: #might need shell = True here
        stdout, stderr = winscp.communicate('\n'.join(cmds))
    if winscp.returncode:
        # WinSCP returns 0 for success, so upload failed
        raise UploadFailed

这是简化的（并使用 Python 3），但你明白了。

I needed to do this and found that code similar to this worked well:

from subprocess import Popen, PIPE

WINSCP = r'c:\<path to>\winscp.com'

class UploadFailed(Exception):
    pass

def upload_files(host, user, passwd, files):
    cmds = ['option batch abort', 'option confirm off']
    cmds.append('open sftp://{user}:{passwd}@{host}/'.format(host=host, user=user, passwd=passwd))
    cmds.append('put {} ./'.format(' '.join(files)))
    cmds.append('exit\n')
    with Popen(WINSCP, stdin=PIPE, stdout=PIPE, stderr=PIPE,
               universal_newlines=True) as winscp: #might need shell = True here
        stdout, stderr = winscp.communicate('\n'.join(cmds))
    if winscp.returncode:
        # WinSCP returns 0 for success, so upload failed
        raise UploadFailed

This is simplified (and using Python 3), but you get the idea.
