Question

我正在尝试创建一个类似的日志文件：

set logFilePath to (path to desktop folder as string) & "waiting.scpt.log" -- "/tmp/waiting.scpt.log" as text

-- set logFilePath to (path to "temp" from user domain as text) & "waiting.scpt.log"
try
    close access file logFilePath
on error err
    display dialog err
end try

set logFile to open for access logFilePath with write permission

我收到一个对话框File file tlv-mp3u2:Users:idror:Desktop:waiting.scpt.log wasn’t open.，然后是错误error "File file tlv-mp3u2:Users:idror:Desktop:waiting.scpt.log is already open." number -49 from file "tlv-mp3u2:Users:idror:Desktop:waiting.scpt.log" to «class fsrf»

我将有问题的文件移到了垃圾箱并再次运行了脚本，结果相同

另外，我真正想要的是在/ tmp下打开文件，但如果我尝试了，我会收到“文件访问错误”（-54）

我放弃了在谷歌寻找答案......所以请帮忙

Answer 1

我不明白你的电话顺序。 Applescript访问文件的方式总是一样的：

打开文件并存储指向已打开文件的文件ID
如果需要，请获取文件末尾的索引（需要在末尾添加文本）
读/写您想要的内容
关闭对文件ID

您的代码段看起来就像是在打开文件之前尝试关闭。如果开放工作（应该只有一次）文件仍然打开，因为你没有关闭它。也许重启可以帮助或安全地清空垃圾桶。

要做日志，我建议：

set logFilePath to (path to desktop folder as string) & "waiting.scpt.log"
doLog(logFilePath, "A new line to log!")

on doLog(pathToLogFile, logText)
    try
        -- open the file at logFilePath and store the file id
        set logFile to open for access pathToLogFile with write permission
        -- write the given text to the file, starting at the end of file to append
        write logText & return to logFile starting at (get eof logFile) + 1
        -- close the file asap
        close access logFile
    on error
        -- if something went wrong, finally try to close the file!
        try
            close access logFile
        end try
    end try
end doLog

评论后更新：

我在处理程序中添加了第三个参数。要删除您必须{{1}}的文件内容，如下所示：

set the eof to 0

Answer 2

CTRL-Click AppleScript并查看菜单Error Handlers=>Write Error to Log - 代码会准确显示其完成情况。

无法打开文件进行写作
