如何检查网络路径是否存在? [英] How to check if a network path exist?

问题描述

在 linux 中使用 python 知道网络路径(例如//192.168.1.1/test)是否存在的最佳方法是什么?

What is the best way to know if a network path(e.g. //192.168.1.1/test) exist using python in linux?

推荐答案

如果路径"是指 Internet URL，则需要查看 urllib 模块.

If by "path" you mean an internet URL, you'll want to look at the urllib module.

from urllib import urlopen
try:
    urlopen(path)
except IOError:
    pass # does not exist
else:
    pass # does exist

如果通过路径"表示Windows UNC，则需要使用os模块.

If by "path" you mean a Windows UNC, then you'll want to use the os module.

import os
os.path.isdir(path)

注意，我发现Windows UNC路径有些不稳定.根据您的网络设置和权限，可能无法访问它们.

Note, I've found the Windows UNC paths somewhat flakey. Depending on your network setup and permissions, they may or may not be accessible.
