AppleScript的，POSIX文件名和山獅

Question

當我使用雪豹，我創建我的AppleScript時，多次使用以下模式：

on run args 
    set filePath to POSIX file (item 1 of args) as alias 
     ... 
end run 

升級到山獅後，上面的腳本似乎產生一個警告，但：

2012-08-10 15:12:12.305 osascript[54131:303] 
CFURLGetFSRef was passed this URL which has no scheme 
(the URL may not work with other CFURL routines): path/to/input/file.ext 

任何人都可以啓發的錯誤的含義？

Answer 1

這個發現應該澄清的問題和解決方案。因此，首先與問題

TB1T-Bboot:$ cat tmp.applescript 
tell application "Finder" 
     set MacOSpath to POSIX file "test-file" as alias 
end tell 
TB1T-Bboot:$ osascript tmp.applescript 
2012-09-24 22:25:50.022 osascript[2564:707] CFURLGetFSRef was passed this URL which has no scheme (the URL may not work with other CFURL routines): test-file 
alias TB1T-Bboot:Users:archive:test-file 
TB1T-Bboot:$ 

現在沒有問題：

TB1T-Bboot:$ cat tmp.applescript 
tell application "Finder" 
     set MacOSpath to POSIX file "/Users/archive/test-file" as alias 
end tell 
TB1T-Bboot:$ osascript tmp.applescript 
alias TB1T-Bboot:Users:archive:test-file 
TB1T-Bboot:$ 

所以它的抱怨，路徑是相對的，不是絕對的。這個警告不會出現在Lion中。

Answer 2

一個簡單的修復方法是在路徑前加上file:///。 Mountain Lion期望所有內容的URL，因此「裸體」路徑將無法使用。

例如，如果您需要/Users/RobertoAloi/file.txt you would pass in file：/// Users/RobertoAloi/file.txt`。
