我正在编写一个脚本，允许学生将他们的文件上传到计算机实验室（同一网络）教师计算机上的共享文件夹。我有一个工作脚本，在执行时，会将学生机器上UPLOAD文件夹中的所有文件复制到教师机器上的SUBMISSIONS文件夹中。但是，如果教师计算机上已存在某个文件，则该脚本会挂起。
我需要能够测试教师机器上是否存在单个文件，并且（a）弹出一条消息，说明“此文件已存在，重命名并再次上传”或（b）附加内容用于区分它的文件名...随机数或“副本1”等。
理想情况下，我希望它作为文件夹操作运行。将文件添加到“UPLOAD”文件夹后，它将自动发送给教师。但我不希望文件复制到同名文件......或者脚本挂起。
欢迎任何想法或替代方法。
这是我的代码：
set home_path to path to home folder as string
set work_folder to alias (home_path & "Desktop:" & "Upload")
try
mount volume "afp://[LOGIN INFO].local/Submissions"
set this_folder to result as alias
tell application "Finder"
tell application "Finder"
duplicate every file of work_folder to this_folder
end tell
eject this_folder
end tell
end try

我认为如果你的try-block有一个错误的阻止通知你任何错误会有所帮助。
try
# try stuff here
j # this will compile but will throw a runtime error and you can see the error
on error error_message number error_number
display alert "Error: " & error_message & return & return & (error_number as text)
end try

此脚本会将每个文件复制到已装入的卷。如果目标中存在具有相同名称的文件，则会在复制文件名的末尾添加一个数字并尝试该操作。
示例：如果文件夹中已存在 test.doc ，则脚本将尝试使用名称 test_1.doc 复制它，依此类推..
永远不会重命名原始文件，也不会覆盖旧文件。 该脚本已完全注释，以解释它正在做什么。
** Update2 **
复制到目标代码现在位于它自己的处理程序中。 原始文件由查找器标签索引6（绿色）标记，表示已成功复制。
这也会通过使用索引颜色作为检查来阻止同一原始文件被复制两次。如果它被标记为索引标签7，则将被忽略。
如果您想使用脚本将成功复制的文件移到另一个文件夹中，则可以。但是我没有在这个剧本中这样做过。

行。我再次尝试编写一些代码。这是我的版本。
它与原始海报发布的代码有所不同。
它将文件和文件夹复制到服务器上的新文件夹中，并带有时间戳，以解决服务器上是否已存在某些文件的问题。
我更改了重复语句的措辞，重复复制每个“文件”以复制每个“项目”，以便文件夹也重复。
我在try-statement中输入了一个on-error块来显示任何错误。
我激活Finder，以便您可以看到进度窗口。
如果没有错误，我会在最后弹出一个对话框。
我遇到了一个我必须解决的问题：
我认为以下代码应该可以正常工作。这几乎是100％的AppleScript。它只使用一次对shell的调用，即获取当前日期并将其格式化为服务器上创建的新文件夹的时间戳。
# set the path to the "work_folder" where the files are to be uploaded
set home_path to path to home folder as string
set work_folder to alias (home_path & "Desktop:" & "Upload")
# duplicate the files and folders in work_folder to the server
try
# TODO set the name of your server here
set the_volume to mount volume "afp://32-bit.local/Submissions"
set destination_path to the_volume as text
set folder_name to getTimeStamp()
tell application "Finder"
activate
set new_folder to make new folder at alias destination_path with properties {name:folder_name}
duplicate every item of work_folder to new_folder
eject the_volume
display alert "Successfully uploaded the files and folders"
end tell
on error error_message number error_number
if error_number is not equal to -128 then
display alert "Error: " & error_message & return & return & (error_number as text)
end if
end try
# This function returns the current date and time as a time-stamp of the form yyyy-mm-dd-hh-ss
# This function uses a shell script because it's just a lot easier to do than in AppleScript
on getTimeStamp()
set time_stamp to do shell script "date '+%Y-%m-%d-%H-%M-%S'"
return time_stamp
end getTimeStamp

这是调试的另一个想法。您可以调用“显示对话框”以便能够知道脚本失败的位置：
display dialog "Entering script"
set home_path to path to home folder as string
display dialog "home_path: " & home_path
set work_folder to alias (home_path & "Desktop:" & "Upload")
display dialog "work_folder: " & work_folder as string
try
mount volume "afp://32-bit.local/Submissions"
set this_folder to result as alias
display dialog "this_folder: " & this_folder as string
tell application "Finder"
display dialog "Inside of the first tell application Finder"
tell application "Finder"
display dialog "About to call duplicate"
duplicate every file of work_folder to this_folder
display dialog "Just returned from calling duplicate"
end tell
display dialog "About to call eject"
eject this_folder
display dialog "Just returned from call to eject"
end tell
on error error_message number error_number
display alert "Error:" & error_message & return & return & (error_number as text)
end try
display dialog "Exiting script"
另一种调试技术是将输出记录到文本文件中。
另一种调试技术是购买AppleScript调试器：
http://www.latenightsw.com/sd4/index.html
我相信这个调试器售价200.00美元对我来说太贵了，但是我用过其他调试器和调试器都是很好的工具，可以让你在运行时“窥视”脚本，看看变量的值和跟踪正在执行哪些代码行。
