Applescript：如何打开当前查找器窗口的完整路径？

我有这个脚本，它工作正常，但当我在网络上打开查找窗口时，它没有给我完整的链接，应该以“卷”开头，如何让它检测到它

    tell application "Finder"
            if exists window 1 then
                set currentDir to POSIX path of ((target of front Finder window) as text)
            else
                set currentDir to POSIX path of (path to desktop folder)
            end if
    end tell
        log currentDir

tell application "Finder"
    if exists Finder window 1 then
        set currentDir to target of Finder window 1 as alias
    else
        set currentDir to desktop as alias
    end if
end tell
log POSIX path of currentDir
