Question

我一直在尝试让系统事件在AppleScript中复制文件而且我一直在失败:)我最终总是得到错误“错误”文件无法复制。“编号-1717”。所以我改变了我的策略并尝试使用Finder来确保我尝试做的事情是正确的。以下是有效的代码：

告诉应用程序“系统事件”

set desktopFolder to (path to desktop folder) as string
set fullPath to desktopFolder & "Temp Export From DO"

set theDOEntries to every file of folder "/Users/jkratz/Dropbox/Apps/Day One/Journal.dayone/entries" whose name extension is "doentry"
repeat with DOEntry in theDOEntries
    set source to path of DOEntry
    log "Source file: " & source
    set destination to fullPath as string
    log "Destination folder: " & destination
    tell application "Finder"
        duplicate file source to folder destination with replacing
    end tell
end repeat

告诉

如果我删除了最后一个告诉，以便它使用系统事件，我会得到上面提到的相同错误。 System Events标准套件的字典有一个“重复”命令，所以我不确定这里发生了什么。此外，来自APress的“学习AppleScript，第3版”注：

“系统事件中一个特别恼人的遗漏是它无法复制文件和文件夹;如果你需要这样做，Finder是你最好的选择。”

第3版是从2010年开始。即使在Mountain Lion，这似乎仍然是真的。谁能证实这一点？ 1717错误号列在其他地方作为处理程序错误，我没有使用处理程序。

不幸的是，您无法使用系统事件复制文件 - 您必须使用Finder。即使在adayzdone提供的答案中，系统事件实际上并没有处理重复。

这看起来很有效（因为它在系统事件告诉块中）...

tell application "System Events"
    duplicate myFile to myFolder
end tell

...但是如果你检查事件日志，你会发现Finder实际上正在执行复制。在幕后，您将两个Finder对象传递给系统事件。系统事件不知道如何处理Finder对象，因此执行被传递给对象＆＃39;所有者，Finder，执行命令。

对于AppleScript中的文件复制，遗憾的是，您只能通过do shell script使用Finder或命令行。

尝试：

tell application "Finder" to set desktopFolder to (path to desktop folder as text) & "Temp Export From DO" as alias
tell application "System Events" to set theDOEntries to every file of folder "/Users/jkratz/Dropbox/Apps/Day One/Journal.dayone/entries" whose name extension is "doentry"
repeat with DOEntry in theDOEntries
    log "Source file: " & DOEntry
    log "Destination folder: " & desktopFolder
    tell application "Finder" to duplicate file DOEntry to desktopFolder with replacing
end repeat

如果您不需要记录值，您可以简单地：

tell application "Finder" to set desktopFolder to (path to desktop folder as text) & "Temp Export From DO" as alias
tell application "System Events" to set theDOEntries to every file of folder "/Users/jkratz/Dropbox/Apps/Day One/Journal.dayone/entries" whose name extension is "doentry"
tell application "Finder" to duplicate theDOEntries to desktopFolder with replacing

或者：

set desktopFolder to quoted form of (POSIX path of (path to desktop folder as text) & "Temp Export From DO")
do shell script "find '/Users/jkratz/Dropbox/Apps/Day One/Journal.dayone/entries' -name \"*.doentry\" -type f -print0 | xargs -0 -I {} cp -a {} " & desktopFolder

回到您的问题，重复的命令会创建Finder项目的副本。您可以使用系统事件来复制Finder项目，如下所示：

tell application "Finder"
    set myFile to file ((path to desktop as text) & "Test File.txt")
    set myFolder to folder ((path to desktop as text) & "Test Folder")
end tell

tell application "System Events"
    duplicate myFile to myFolder
end tell

AppleScript中的系统事件是否支持重复文件？
