AppleScript读取剪贴板路径打开文件报错，如何解决？

问题场景 #

硬编码文件路径的代码可正常打开文件：

tell application "Finder"
    open POSIX file "/Users/myName/file.pdf"
end tell

但读取剪贴板路径的代码运行失败，报错：Finder got an error: Can’t get POSIX file "/Users/myName/file.pdf"
对应代码：

tell application "Finder"
    set filePath to (the clipboard as text)
    open POSIX file filePath
end tell

问题原因 #

1. 剪贴板中的路径文本可能携带多余的空白字符（换行、空格、制表符）或引号，导致POSIX路径解析失败
2. 在Finder的tell块内直接处理剪贴板，可能受上下文限制影响路径解析

解决代码 #

-- 先在Finder上下文外处理剪贴板内容
set filePath to (the clipboard as text)
-- 清理路径中的多余字符
set cleanedFilePath to my cleanPath(filePath)

-- 调用Finder打开文件
tell application "Finder"
    open POSIX file cleanedFilePath
end tell

-- 路径清理函数：去除首尾空白和多余引号
on cleanPath(inputPath)
    -- 去除首尾空白字符
    set trimmedPath to my trim(inputPath)
    -- 去除首尾引号（如果存在）
    if trimmedPath starts with "\"" and trimmedPath ends with "\"" then
        return text 2 through -2 of trimmedPath
    else if trimmedPath starts with "'" and trimmedPath ends with "'" then
        return text 2 through -2 of trimmedPath
    else
        return trimmedPath
    end if
end cleanPath

-- 去除首尾空白的辅助函数
on trim(inputText)
    set AppleScript's text item delimiters to {" ", return, linefeed, tab}
    set trimmedText to text items of inputText
    set AppleScript's text item delimiters to ""
    return trimmedText as text
end trim

补充说明 #

如果不需要通过Finder打开，也可以直接用系统命令调用默认程序，代码更简洁：

set filePath to (the clipboard as text)
set cleanedFilePath to my cleanPath(filePath)
do shell script "open " & quoted form of cleanedFilePath
