Laravel：将存储/应用程序中安全存储的文件的URL提供给jquery库

问题描述：

I have stored my PDF files using the storage API. To let the browser read PDF I could use the Response::make() but I am using the pdfObject jquery library to display it embedded. And the problem is while using the library, I have to provide the url of pdf:

var pdf = new PDFObject({
   url: **"THE URL TO THE PDF",**
   pdfOpenParams: {
   navpanes: 0,
   toolbar: 0,
   statusbar: 0,
   view: "FitV"
}

How can I give the URL of the securely stored PDF to the library? Any help appreciated!

我使用存储API存储了我的PDF文件。为了让浏览器读取PDF，我可以使用Response :: make（），但我使用pdfObject jquery库来嵌入它。问题是在使用库时，我必须提供pdf的URL： p>

  var pdf = new PDFObject（{
 url：**“THE URL to THE  PDF“，** 
 pdfOpenParams：{
 navpanes：0，
 toolbar：0，
状态栏：0，
视图：”FitV“
} 
  code>  pre> 
  
 如何将安全存储的PDF的URL提供给库？
非常感谢！ p>

You can make a new "loader" controller, from which you can return a pdf header with the desired file. Then instead of calling the file directly, pass its encrypted name as a parameter to the controller and decode it inside:

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

Controller:

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;
});

P.S. The Laravel code is not tested and will mostly likely not work (I am little rusty with it), I tested with pure PHP though, and it worked.
