我不明白為什么我的.htaccess標題設置不起作用。我的.htaccess文件內(nèi)容：Header set Access-Control-Allow-Origin *Header always set Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT"Header always set Access-Control-Allow-Headers "*"RewriteEngine OnRewriteCond %{REQUEST_FILENAME} !-fRewriteRule ^(.*)$ index.php [QSA,L]但是，當我刪除Header并將其添加進來時，index.php一切正常。header("Access-Control-Allow-Origin: *");header("Access-Control-Allow-Methods: PUT, GET, POST, DELETE, OPTIONS");header("Access-Control-Allow-Headers: *");我想念什么？
