如何通过AppleScript实现Apple Mail邮件PDF附件指定目录自动保存？

一、创建Mail规则步骤 #

• 打开Apple Mail，依次点击菜单栏「邮件」→「偏好设置」→「规则」
• 点击「添加规则」，设置触发规则的条件（如特定发件人、主题关键词等）
• 在「执行以下操作」下拉列表中选择「运行AppleScript」，点击「新建脚本」

二、现成AppleScript脚本 #

将以下代码粘贴到新建的脚本编辑器窗口中，修改目标文件夹路径后保存：

using terms from application "Mail"
    on perform mail action with messages theMessages for rule theRule
        -- 替换为你的目标文件夹路径，确保文件夹已存在
        set saveFolder to POSIX file "/Users/你的用户名/Documents/邮件PDF附件" as alias
        
        repeat with eachMessage in theMessages
            set theAttachments to every attachment of eachMessage
            repeat with eachAttachment in theAttachments
                set attachmentName to name of eachAttachment
                -- 过滤PDF格式附件（区分大小写）
                if attachmentName ends with ".pdf" or attachmentName ends with ".PDF" then
                    try
                        -- 覆盖同名文件，如需保留重复文件可移除with replacing参数
                        save eachAttachment in saveFolder with replacing
                    on error errMsg
                        display dialog "保存附件失败: " & errMsg buttons {"确定"} default button 1
                    end try
                end if
            end repeat
        end repeat
    end perform mail action with messages
end using terms from

三、配置注意事项 #

• 替换脚本中的/Users/你的用户名/Documents/邮件PDF附件为实际保存路径，路径需为POSIX格式（macOS标准路径）
• 首次触发规则时，系统会弹出权限请求，需允许Mail访问目标文件夹
• 若需避免覆盖同名文件，可修改脚本添加时间戳，示例：

  -- 在保存前添加时间戳
  set currentDate to current date
  set dateString to (year of currentDate as string) & "-" & (month of currentDate as integer as string) & "-" & (day of currentDate as string) & "_" & (hours of currentDate as string) & "-" & (minutes of currentDate as string)
  set newFileName to text 1 thru -5 of attachmentName & "_" & dateString & ".pdf"
  save eachAttachment in (saveFolder as string) & newFileName
