Open file with path needing character escaping in Go
问题
我有一个文件，os.open() 返回给我一个 no such file or directory 的错误。有没有一个函数可以转义文件名，以获取正确的路径？类似于 net 包中的 QueryEscape 函数，但当然是用于文件路径。
这是路径名："Music/3OH!3 - Streets Of Gold 2010 [Cov+CD][Bubanee]/06. Touchin On My - 30H!3.mp3"
我只是使用一个简单的代码：
srcName := "Music/3OH!3 - Streets Of Gold 2010 [Cov+CD][Bubanee]/06. Touchin On My - 30H!3.mp3"
src, err := os.Open(srcName)
if err != nil {
fmt.Println(err)
return
}
顺便说一下，文件是存在的，只是路径名无法被正确解析。Bash 可以解析的路径是 Music/3OH\!3\ -\ Streets\ Of\ Gold\ \[Cov+CD\]\[Bubanee\]/12.\ Strrets\ Of\ Gold\ -\ 30H\!3.mp3，其中显示了所有需要转义的字符。
英文:
I have a file which os.open() gives me back, no such file or directory. Is there a function which can escape a file name for getting the correct path to it? Something similar to the net package QueryEscape ?, but for file paths of course
Here is the Path name "Music/3OH!3 - Streets Of Gold 2010 [Cov+CD][Bubanee]/06. Touchin On My - 30H!3.mp3"
I'm just using a simple
srcName := "Music/3OH!3 - Streets Of Gold 2010 [Cov+CD][Bubanee]/06. Touchin On My - 30H!3.mp3"
src, err := os.Open(srcName)
if err != nil {
fmt.Println(err)
return
}
The file does exist btw, go just cant follow the path name. The path that bash can follow is Music/3OH\!3\ -\ Streets\ Of\ Gold\ \[Cov+CD\]\[Bubanee\]/12.\ Strrets\ Of\ Gold\ -\ 30H\!3.mp3 which shows all the escaping that is needed.

我在我的机器上（Mac OS 10.8.3）尝试创建相同的目录结构，并且使用你的代码没有问题打开文件。这意味着在打开时路径已经正确转义。
确保你从Music/文件夹的上一级位置运行你的Go程序，或者只使用完整的根路径作为srcName。
英文:
I tried creating the same directory structure on my machine (Mac OS 10.8.3), and I had no trouble opening the file using your code. This means that the path is properly escaped when opening already.
Make sure you're running your go program from a location right above the Music/ folder, or just use the full root path for srcName.
