如何从Mac上的API获取挂载点信息? [英] How to get mount point information from an API on Mac?

问题描述

当我发出mount命令时，我得到如下条目:

When I issue the mount command, I get entries like the following:

//abc@host/b1 on /Volumes/b1 (smbfs, nodev, nosuid, mounted by abc)
//abc@host/b2 on /Volumes/b2 (smbfs, nodev, nosuid, mounted by abc)

这些表明我安装了两个Samba共享.

These indicate that I have two samba shares mounted.

我宁愿不尝试解析mount命令输出，但我确实想检索附加文件系统的挂载点，尤其是从samba中检索.

I'd rather not try to parse mount command outputs, but I do want to retrieve the mount points of of attached filesystems, especially from samba.

Mac上是否有API允许我以C或Shell或Python等方式执行此操作?

Is there a API on the Mac that allows me to do this, either in C, or shell, or Python, etc. ?

推荐答案

您将使用以下方法获得已安装卷的URL数组:

You get an array of URLs for the mounted volumes using:

NSArray* keys = @[ /* ... */ ];
NSArray* urls = [[NSFileManager defaultManager] mountedVolumeURLsIncludingResourceValuesForKeys:keys
                                                                                        options:NSVolumeEnumerationSkipHiddenVolumes];

我马上进入keys数组.一旦有了这些URL，就可以使用NSURL的资源值" API获得有关它们的信息.您可以使用-[NSURL getResourceValue:forKey:error:]获得单个值.使用-resourceValuesForKeys:error:一次可以得到几个.您可以通过在上面传递给NSFileManager方法的keys数组中指定它们来优化对所需值的获取.

I'll get to the keys array in a moment. Once you have those URLs, you can obtain information about them using the "resource value" APIs of NSURL. You get a single value using -[NSURL getResourceValue:forKey:error:]. You get several at a time using -resourceValuesForKeys:error:. You can optimize the fetching of whatever values you're interested in by specifying them in the keys array passed to the NSFileManager method, above.

对于使用网络共享可能很重要的键是NSURLVolumeURLForRemountingKey.其他键在NSURL文档中列出. Command键和Volume键都适用.

A key that may be significant for working with network shares is NSURLVolumeURLForRemountingKey. Other keys are listed in the NSURL docs. Both the Command and Volume keys apply.
