我想要一个AppleScript，让我获取所选的Messages.app对话/聊天的ID或类似内容，然后再使用AppleScript打开正确的消息对话/聊天对应这个ID。
使用Mail.app我可以执行以下操作：
tell application "Mail"
set selectedMessages to selection
set theMessage to item 1 of selectedMessages
set messageid to message id of theMessage
-- Make URL (must use URL-encoded values for "<" and ">")
set urlText to "message://" & "%3c" & messageid & "%3e"
return urlText
end tell
但是使用Messages.app，有selection个对象。
尝试获取the clipboard的内容以查看是否有任何可以使用的ID或值，但看起来剪贴板访问不像通过cocoa那样强大编程（在那里你可以获得大量的元数据和替代的剪贴板内容）。
双击对话，以便用它自己的窗口打开。试图获取此窗口的ID，然后稍后打开它。没有工作。

将此 AppleScript 脚本用作脚本（。scpt）或应用程序（.app ），您需要先在 Messages.app 的会话列表中选择目标会话，以便此后始终返回，并且最初运行两次。然后，这会将property theSelectedRow : 0设置为property theSelectedRow : i，其中i的值将是property thisName : ""设置为值，即description of UI element 1 of row i中包含的名称。在这两个属性的值之间，脚本将始终将焦点设置回后续选定的目标对话即使其row 数字发生更改，它仍然存在。如果所选目标会话不再存在，则会通知用户。
阅读脚本中的注释，以便了解代码正在做什么。
AppleScript 代码：
-- # These two properties are used to hold information about the target
-- # conversation in order to always set focus to it when the script runs
-- # after the initial runs. Initially, the script must be run twice to have
-- # the selected target conversation be returned to on subsequent runs.
-- #
-- # Note: This is also true anytime the script is modified or compiled, in
-- # Script Editor, as that resets the value of a property to its original value.
property thisRowNumber : 0
property thisName : ""
-- # See if the shift modifier key was pressed. This allows
-- # setting the focus to a different target conversation.
-- # Note: Unlike when the script is modified or compiled from within
-- # Script Editor, when invoking this, the change is immediate when
-- # done after the initial runs to have the values of the properties set.
if my shiftKeyWasDown() then set thisRowNumber to 0

注意：这是在OS X 10.8.5下编写和测试的，但是，我相信它将在OS X / macOS和Messages.app的更高版本下以的形式工作，即使是当前的macOS 10.13 beta。
此外，脚本使用最少的错误处理，并且没有任何try 语句和on error 处理程序 。虽然除delay 命令中的值之外，可以根据需要进行调整，但如果没有额外的错误处理，它应该可以正常运行。与往常一样，用户可以根据需要添加/删除和/或调整代码。
