Accessing a Windows shared drive on a remote server in Python
提问by Stuart
This seems like a simple problem, but I'm having trouble figuring it out.
这似乎是一个简单的问题，但我很难弄清楚。
I set up a shared folder on a remote server so that the folder shows up in the Windows Explorer as follows: \\server-name\shared-directory. I am able to read from that folder remotely and write to that folder remotely via the Windows Explorer. When I try to access that file via a python script, however, I it says the directory does not exist.
我在远程服务器上设置了一个共享文件夹，以便该文件夹在 Windows 资源管理器中显示如下：\\server-name\shared-directory。我能够远程读取该文件夹并通过 Windows 资源管理器远程写入该文件夹。但是，当我尝试通过 python 脚本访问该文件时，它说该目录不存在。
I have administrative rights to the server and gave myself access to the shared drive (I verified this by copying files via Windows Explorer).
我拥有服务器的管理权限，并允许自己访问共享驱动器（我通过 Windows 资源管理器复制文件来验证这一点）。
In python, I am accessing the drive as follows (although I tried several different ways and had no success):
在python中，我按如下方式访问驱动器（虽然我尝试了几种不同的方法但都没有成功）：
os.access('\\server-name\path-to-shared-directory', os.W_OK)
Any suggestions on what I might be doing wrong?
关于我可能做错了什么的任何建议？
EDIT:
编辑：
In response to questions, I am actually trying to copy files using the script, os.access was just used to see if the directory had write access. The copy code I am using is as follows:
在回答问题时，我实际上是在尝试使用脚本复制文件，os.access 只是用于查看目录是否具有写访问权限。我使用的复制代码如下：
def copy_folder(src, dest):
if not os.access(dest, os.W_OK):
return(False)
cmd = ['xcopy', '/E', '/J', '/Y', '/I', src, dest]
p = subprocess.Popen(args=cmd, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)
out, err = p.communicate()
print 'out: %s' % out
print 'err: %s' % err
return(True)
copy_folder(my_source_directory, '\\server-name\path-to-shared-directory')
This returns 'Invalid drive specification' as an error.
这将返回“无效驱动器规范”作为错误。

You should have no problem accessing files via the UNC path that you are already attempting to use, but I would recommend formatting it a bit differently to help with escaping:
通过您已经尝试使用的 UNC 路径访问文件应该没有问题，但我建议对其进行稍微不同的格式化以帮助转义：
src = r'C:\path\to\source'
dest = r'\server-name\path-to-shared-directory'
And you don't need stdin:
你不需要stdin：
p = subprocess.Popen(cmd,
stdout=subprocess.PIPE,
stderr=subprocess.PIPE,
shell=True)
Normally you would be able to use forward slashes for paths in python, but since you are calling out to a shell command, the backslashes are still needed.
通常，您可以在 python 中对路径使用正斜杠，但是由于您调用的是 shell 命令，因此仍然需要反斜杠。
