问Laravel:将存储/应用程序上安全存储的文件的url提供给jquery库

EN

var pdf = new PDFObject({
    url: "site.com/controller/method/<?php Crypt::encrypt('filename.pdf') ?>",
    //...
}

Route::get('/controller/method/{filename}', function($filename) {
    // Laravel is ignoring the header method and is sending a plain html/txt :(
    // So a normal php header can do the workaround
    header("Content-type: application/pdf");

    $filename = '/url/to/pdf/' . Crypt::decrypt($filename);

    $response = Response::make(readfile($filename), 200);
    $response->header('Content-Type', 'application/pdf');
    return $response;
});
