Applescript中的错误-10004和错误-10000是什么？

Question

我有一个在我的计算机上工作的Applescript，但不在我同事的计算机上。我在操作路径时遇到了两个错误：-10004和-10000。我有一个关于如何解决这个问题的想法，但是首先我想了解这些错误代码。

下面是脚本(我删除了无用的部分，完整的版本在github上)：

-- export all layers to image files

-- Settings
property exportFileExtension : "png"
property ADD_CANVAS_NUMBER : true
-- End of Settings

on file_exists(FileOrFolderToCheckString)
   try
       alias FileOrFolderToCheckString
       return true
   on error
       return false
   end try
end file_exists

tell application "OmniGraffle Professional 5"
    set theWindow to front window
    set theDocument to document of theWindow
    set theFilename to name of theDocument
    -- remove .graffle
    -- FIRST ERROR IS HERE -10004
    set theFilename to text 1 thru ((offset of "." in theFilename) - 1) of theFilename

    set export_folder to (choose folder with prompt "Pick the destination folder") as string
    set export_folder to export_folder & theFilename & ":"

    -- create folder
    if file_exists(export_folder) of me then
        try
            display alert "The file already exists. Do you want to replace it?" buttons {"Cancel", "Erase"} cancel button 1
        on error errText number errNum
            if (errNum is equal to -128) then
                return
            end if
        end try

        -- deletes the folder (necessary because some layers may have been renamed
        do shell script "rm -rf " & quoted form of POSIX path of export_folder

    else
        -- creates the folder
        do shell script "mkdir -p " & quoted form of POSIX path of export_folder
    end if

    set canvasCount to count of canvases of theDocument

    set i to 0
    repeat with canvasNumber from 1 to canvasCount
        set theCanvas to canvas canvasNumber of theDocument
        set canvas_name to name of theCanvas
        set canvas of theWindow to theCanvas
        set layerCount to count of layers of theCanvas

        -- ...

        set area type of current export settings to current canvas
        set draws background of current export settings to false
        set include border of current export settings to false

        set canvas_filename to ""
        -- ...
        set canvas_filename to canvas_filename & canvas_name

        repeat with layerNumber from 1 to layerCount
            set theLayer to layer layerNumber of theCanvas

            if (theLayer is prints) and (class of theLayer is not shared layer) then
                set layer_name to name of theLayer as string
                set filename to canvas_filename & " - " & layer_name & "." & exportFileExtension
                set export_filename to export_folder & filename

                -- show the layer, export, then hide the layer
                if character 1 of layer_name is not "*" then
                    set visible of theLayer to true
                    -- SECOND ERROR IS HERE -1000
                    save theDocument in export_filename
                    set visible of theLayer to false
                end if

            end if

        end repeat

    end repeat
end tell

这是日志：

tell application "OmniGraffle Professional 5"
   get window 1
       --> window id 5032
   get document of window id 5032
       --> document "MSD.graffle"
   get name of document "MSD.graffle"
       --> "MSD.graffle"
   offset of "." in "MSD.graffle"
       --> error number -10004
end tell
tell current application
   offset of "." in "MSD.graffle"
       --> 4
end tell
tell application "OmniGraffle Professional 5"
   choose folder with prompt "Pick the destination folder"
       --> alias "Macintosh HD:Users:Romain:Desktop:Temp:"
   display alert "The file already exists. Do you want to replace it?" buttons {"Cancel", "Erase"} cancel button 1
       --> {button returned:"Erase"}
   do shell script "rm -rf '/Users/Romain/Desktop/Temp/MSD/'"
       --> error number -10004
end tell
tell current application
   do shell script "rm -rf '/Users/Romain/Desktop/Temp/MSD/'"
       --> ""
end tell
tell application "OmniGraffle Professional 5"
...
...
   save document "MSD.graffle" in "Macintosh HD:Users:Romain:Desktop:Temp:MSD:1- Navigation - 1Layout.png"
       --> error number -10000
Result:
error "OmniGraffle Professional 5 got an error: AppleEvent handler failed." number -10000

谢谢!

我更新了脚本，但仍然得到了错误-10000。以下是修改后的行：

save theDocument in file exportFilename

和

-- Create folder if does not exist, remove it otherwise
-- Shell script should not be executed inside tell application block
if file_exists(export_folder) of me then
    try
        display alert "The file already exists. Do you want to replace it?" buttons {"Cancel", "Erase"} cancel button 1
    on error errText number errNum
        if (errNum is equal to -128) then
            return
        end if
    end try

    tell me
        -- Delete the folder
        do shell script "rm -rf " & quoted form of POSIX path of export_folder
    end tell

else
    tell me
        -- Create the folder
        do shell script "mkdir -p " & quoted form of POSIX path of export_folder
    end tell
end if

Answer 1

错误-10000 - -10015是事件注册表错误。

错误-10000本身并不是一个目标错误，因为在大多数情况下，它会抛出an -1708。大多数情况下，这不是一个目标错误，而是一个不完整的命令或错误的使用括号。如果你用：

save theDocument in file export_filename

error -10004是一个违反权限的错误，这意味着您正在处理不允许的文件。可能不允许您删除文件并执行shell脚本命令，应该始终在tell应用程序块之外使用。问题是目标应用程序可以作为脚本以外的另一个用户运行。我并不是说是错误，但有可能这就是问题所在。否则，您只需获得足够的权限，并且需要向用户询问管理员权限。

do shell script "do something" with administrator privileges.

Answer 2

我还没有找到这些错误代码被记录的地方，但它们主要处理的是目标应用程序无法处理的事件。前两个错误- -10004来自在一个应用程序tell语句(偏移量和do shell脚本)中使用一个标准添加命令--应用程序不知道这些命令是什么，将错误传递到AppleScript，但是AppleScript知道它们是什么，并执行它们。

我没有OmniGraffle，但最后一个错误是告诉您保存命令无法执行，这可能是由于目标不是文件说明符的问题--它只是一个文本字符串，因此您可能不得不将其强制放入命令想要的东西中。
