Question

我是AppleScript小组，我离购买类型作家并进入山区不远。

请允许任何人向我解释为什么会失败：

set mah_file to POSIX file "/Users/me/folder/fileinfo.txt"
set mah_data to "some text!!!!!!"

on write_to_file(this_data, target_file, append_data) -- (string, file path as string, boolean)
    try
        set the target_file to the target_file as text
        set the open_target_file to ¬
            open for access file of target_file with write permission
        if append_data is false then ¬
            set eof of the open_target_file to 0
        write this_data to the open_target_file starting at eof
        close access the open_target_file
        return true
    on error
        try
            close access file target_file
        end try
        return false
    end try
end write_to_file

write_to_file(mah_data, mah_file, true)

即使这成功了：

set mah_file to choose file
set mah_data to "some text!!!"

-- the rest is identical

我试过了：

set mah_file to POSIX file "/Users/me/folder/fileinfo.txt" as file

和

set mah_file to POSIX file "/Users/me/folder/fileinfo.txt" as alias

和

set mah_file to POSIX file "/Users/me/folder/fileinfo.txt" as text

由于AppleScript无法告诉我为什么这不起作用，所以我很好，真的失去了理智。

Answer 1

忽略file和POSIX file个关键字：

set mah_file to "/Users/me/folder/fileinfo.txt"
...
set the open_target_file to open for access mah_file with write permission

Answer 2

默认情况下，

read和write也使用主要编码（如MacRoman或MacJapanese）。添加as «class utf8»以保留UTF-8文件中的非ASCII字符。

写作：

set b to open for access "/tmp/1" with write permission
set eof b to 0
write "α" to b as «class utf8»
close access b

追加：

set b to open for access "/tmp/1" with write permission
write "ア" to b as «class utf8» starting at eof
close access b

读：

read "/usr/share/dict/connectives" as «class utf8»

Answer 3

您可以将echo命令与＆gt;＆gt;结合使用将文本写入文件

如果纺织品不存在，将会创建一个新的纺织品

如果文本文件已存在且

你使用＆gt;您可以覆盖具有相同名称的现有纺织品

你使用＆gt;＆gt;文本将被添加到现有文件

set mypath to "/Users/" & (short user name of (system info)) & "/Desktop/file.txt" as string
set myText to "text to write in the text file" as string

do shell script "echo " & "\"" & myText & "\"" & ">>" & mypath

和mypath是和POSIX路径

希望这就是你在寻找的东西

AppleScript：提供POSIX路径时尝试写入文件
