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.

我不想尝试解析 mount 命令输出，但我确实想检索附加文件系统的安装点，尤其是从 samba.

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 上是否有允许我在 C、shell 或 Python 等中执行此操作的 API?

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

您可以使用以下方法获取已安装卷的 URL 数组:

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

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

稍后我将介绍 keys 数组.获得这些 URL 后，您可以使用 NSURL 的资源值"API 获取有关它们的信息.您可以使用 -[NSURL getResourceValue:forKey:error:] 获得单个值.您可以使用 -resourceValuesForKeys:error: 一次获得多个.您可以通过在传递给上述 NSFileManager 方法的 keys 数组中指定它们来优化对您感兴趣的任何值的获取.

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.

对于处理网络共享可能很重要的一个键是 NSURLVolumeURLForRemountingKey.NSURL 文档中列出了其他键.命令和音量键都适用.

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.
