下面的applescript 将AppUninstaller.scpt 注册为垃圾文件夹的文件夹操作。
在 Mac OSX 10.7 和 10.8 中注册文件夹操作脚本工作正常。
在 10.9 中，我收到错误“ Attach error System Events got an error: Can't make alias “Macintosh HD:Users:[username]:.Trash:” into type specifier。
执行此语句时发生错误
attach action to _trashFolder using _uninstallerScriptPath
完整的脚本如下。
on run
tell utils
init()
registerFolderAction()
end tell
end run
script utils
property _uninstallerScript : "AppUninstaller.scpt"
property _resRelativePath : ":Applications:TestDemo.app:Contents:Resources:"
property _folderActionScriptRelativePath : "Scripts:Folder Action Scripts"
global _resPath
global _trashFolder
global _uninstallerScriptPath
on init()
-- Setup paths
set _trashFolder to path to trash folder
set _uninstallerScriptPath to getUninstallerScript()
-- Add boot disk name to App relative path
tell application "Finder"
set startupDisk to (name of startup disk)
set _resPath to startupDisk & _resRelativePath
end tell
set scriptFolderPath to getScriptPath()
-- Copy folder action script file from appbundle to scripts folder
copyScript()
end init
on registerFolderAction()
try
tell application "System Events"
set folder actions enabled to true
log _uninstallerScriptPath
-- problem with below statement.
attach action to _trashFolder using _uninstallerScriptPath
end tell
on error msg
display dialog "Attach error " & msg
end try
end registerFolderAction
on getScriptPath()
return ((path to library folder from user domain) as string) & _folderActionScriptRelativePath
end getScriptPath
on getUninstallerScript()
return getScriptPath() & ":" & _uninstallerScript
end getUninstallerScript
-- copying the script inside app bundle into scripts folder.
on copyScript()
tell application "Finder"
set srcFile to _resPath & _uninstallerScript
set dstFile to my getScriptPath()
log "Src File " & srcFile & " dstFolder " & dstFile
duplicate file srcFile to dstFile with replacing
end tell
end copyScript
end script
最佳答案
查看错误(并在我自己测试之后)似乎在小牛之前的系统中，当参数是别名时，attach action to 命令的第一个参数被正确强制转换为文件/文件夹对象说明符。在小牛队中，这种强制不会发生，并且会发生错误，因为给定的参数不是对象/类型说明符而是别名类。 attach action to 的第一个参数需要是一个对象/类型说明符，以便您可以通过在调用命令时强制强制转换来解决您的问题。
attach action to folder (_trashFolder as text) using _uninstallerScriptPath
你可以用参数
using 做同样的事情关于macos - applescript (10.9) 不能将别名变成类型说明符，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/22628173/
