os.listdir等在共享Windows路径上失败(Python 2.5) [英] os.listdir etc fails on shared windows path (Python 2.5)

问题描述

在解析共享路径(服务器上的共享路径，例如\ storage \ Builds)时，我看到一些奇怪的行为

I am seeing some weird behavior while parsing shared paths (shared paths on server, e.g. \storage\Builds)

我正在读取文本文件，其中包含我要进一步处理的目录路径.为此，请按以下步骤操作:

I am reading text file which contains directory paths which I want to process further. In order to do so I do as below:

def toWin(path):
    return path.replace("\\", "\\\\")

for line in open(fileName):
    l = toWin(line).strip()
    if os.path.isdir(l):
        print l # os.listdir(l) etc..

这适用于本地目录，但不适用于共享系统上指定的路径.

This works for local directories but fails for paths specified on shared system.

e.g. 
    E:\Test -- works
    \\StorageMachine\Test -- fails [internally converts to \\\\StorageMachine\\Test]
    \\StorageMachine\Test\ -- fails  [internally converts to \\\\StorageMachine\\Test\\]

但是，如果我打开python shell，导入脚本并使用相同的路径字符串调用函数，那么它将起作用！

But if I open python shell, import script and invoke function with same path string then it works!

在两种情况下，解析Windows共享路径的行为似乎有所不同.

It seems that parsing windows shared paths is behaving differently in both cases.

有什么想法/建议吗?

推荐答案

必须将输入转换为正斜杠(unix样式)，以便os.*模块正确解析.

Have to convert input to forward slash (unix-style) for os.* modules to parse correctly.

更改代码如下

def toUnix(path):
    return path.replace("\\", "/")

现在所有模块都能正确解析.

Now all modules parse correctly.
