在Applescript中寫入文件 - 不工作

Question

我一直在試圖寫入一個文件xmlhttp GET請求的結果。我試過下面的代碼：

set the_file to "/Users/xxxx/Documents/outputvals.txt" as file specification 

set the_data to costItems 

try 
    open for access the_file with write permission 
set eof of the_file to 0 
write (the_data) to the_file starting at eof as list 
close access the_file 
end try 

但是它似乎沒有寫入任何文件。理想情況下，我想將xml'costItems'寫入文本文件的末尾。

Answer 1

通常，如果您想對文件或文件夾執行任何操作，它必須是完整的alias引用。只需將as file specification更改爲as POSIX file as alias，那部分就會起作用！並且，刪除as list並刪除行set eof of the_file to 0。假設文件已經包含了信息，你基本上告訴腳本文件的結尾是文件的開始。

我希望這有助於！

編輯：我不知道爲什麼你的代碼不能正常工作（它對我來說）。好吧，我想你可以試試下面的（有點哈克，雖然，但哦：P）： 集the_file到「/用戶/尼克/文檔/ outputvals

tell application "Finder" 
    try 
     set the_file to "/Users/xxxx/Documents/outputvals.txt" as POSIX file as alias 
    on error --file doesn't exist yet, so create it 
     set the_file to (make new document file at ("/Users/xxxx/Documents/" as POSIX file as alias) with properties {name:"outputvals", text:""}) 
     --Normally, when you're creating documents in this fashion, you would put the text you want in the document after the 'text' property, but for your sake I will use the alternative :) 
    end try 
end tell 
set the_data to costItems 
try 
    open for access the_file with write permission 
    write the_data to file the_file starting at eof 
    close access the_file 
on error --you never know when errors will crop up (when it comes to reading and writing files); better to be safe than sorry 
    try 
     close access the_file 
    end try 
end try
