尝试检查路径时出现错误

I am trying to check windows dir in my golang app. Here is my code

func createWalletDirectory(path string) (err error) {
    _, err = os.Stat(path)

    if os.IsNotExist(err) {
        return err
    }

    path = filepath.FromSlash(path)

    path = path + string(os.PathSeparator) + DirectoryName

    err = os.Mkdir(path, 0666)

    return
}

So on the first line of the function I am getting an error look like this

invalid character 'i' in string escape code

Example path : C:\Users

Note: The path I am getting from users via POST request So I need to make a code which will check crossplatform paths. How can I solve this error ?

In Go strings enclosed by double quotes, a backslash starts an escape code, e.g. or \u2318. To avoid this, you have two options:

• use a double backslash (\\), e.g. "C:\\Users"
• use backticks (`) instead of double quotes to define a "raw string", e.g. `C:\Users`

Further reading

You can use path package to work with the urls('path/filepath' for the file paths) which also contributes in platform independency. So you can do following to create the path

givenPath = filepath.Join(DirectoryName, path)

There is also another way of doing this

path := strings.Join([]string{DirectoryName, path}, string(os.PathSeparator))
