How to serve the data returned from laravel Storage::disk('private')->get($file) as PDF

Question

My question is about the problem in link below :

Understanding file storage and protecting contents Laravel 5

I need to use the same method mentioned in above example but instead of an image I need to provide a download link for PDF file or a link to open PDF file in browser and I can't do that because, as mentioned in above example's comments The Storage::disk('private')->get($file) returns the CONTENT of the file NOT the URL.

Please tell me how can I convert the row data (content of file) to a file and provide the link for the users inside the view.

The user `aceraven777` answered the example link I hope he answers this too :) — kianoosh Azarvandi, Feb 21 '20 at 09:31

You should follow the below steps:

I have store pdf file into storage/app/pdf

In controller:

public function __construct()
{
    $this->middleware('auth');
}

public function index(Request $request, $file)
{   

    $file = storage_path('app/pdf/') . $file . '.pdf';

    if (file_exists($file)) {

        $headers = [
            'Content-Type' => 'application/pdf'
        ];

        return response()->file($file, $headers);
    } else {
        abort(404, 'File not found!');
    }        
}

if laravel below 5.2: Add use Response; above controller class in the controller.

public function index(Request $request, $file)
{   

    $file = storage_path('app/pdf/') . $file . '.pdf';

    return Response::make(file_get_contents($file), 200, [ 'Content-Type' => 'application/pdf',
        'Content-Disposition' => 'inline; filename="'.$file.'"'

    ]);       
}

In web.php

Route::get('/preview-pdf/{file}', 'Yourcontroller@index');

In the blade view:

<a href="{{ URL('/preview-pdf/'.$file )}}" target="_blank">PDf</a>

It doesn't work, I tried it but it returns a blank page with the url of file in top-left corner – kianoosh Azarvandi Feb 21 '20 at 09:59
@kianooshAzarvandi Can you check the URL of the file is correct or not when black page showing? – Amit Senjaliya Feb 21 '20 at 10:00
For the record I use this : `$url = Storage::disk('private')->url($file);` in a separate controller which is responsible for creating route to the link of files – kianoosh Azarvandi Feb 21 '20 at 10:04
@kianooshAzarvandi I have tested in my laravel project for you and it is working. Let me know any issue. – Amit Senjaliya Feb 21 '20 at 10:33
You are not making it private, the whole thing is about file security and meanwhile serving the file through Storage::disk('private') only to authenticated users and it is done here: https://stackoverflow.com/questions/57462558/understanding-file-storage-and-protecting-contents-laravel-5 – kianoosh Azarvandi Feb 21 '20 at 10:41
@kianooshAzarvandi No no, It is a private folder which is not accessible directly like `http://yourdomain.com/filename`. – Amit Senjaliya Feb 21 '20 at 10:55
@kianooshAzarvandi Also private means `644` file permission right? – Amit Senjaliya Feb 21 '20 at 10:56
@kianooshAzarvandi If you want to serve only authenticated user should use `auth()`. I have updated my controller code. – Amit Senjaliya Feb 21 '20 at 11:04
result is the same,opens a new tab and then downloads the file, I need it to open the file – kianoosh Azarvandi Feb 21 '20 at 11:31
@kianooshAzarvandi Replace return download to `file`. I have updated – Amit Senjaliya Feb 21 '20 at 11:37
Error : Call to undefined method: League\Flysystem\Filesystem::file – kianoosh Azarvandi Feb 21 '20 at 11:42
@kianooshAzarvandi Your Laravel version is below 5.2? right then use another method. I have added in my controller. – Amit Senjaliya Feb 21 '20 at 11:55

According to the Laravel documentation you can simply use the download method on the Storage facade.

From your controller, return the result of the command.

return Storage::disk('private')->download($file);

Thank you so much for your help. It worked exactly as I expected. – kianoosh Azarvandi Feb 21 '20 at 09:39
one more question, how can I open the file in browser instead of downloading it ? – kianoosh Azarvandi Feb 21 '20 at 09:40
@kianooshAzarvandi You need to get URL and then add this URL in an anchor tag with the target `blank`. I have updated my answer. – Amit Senjaliya Feb 21 '20 at 09:46
@kianooshAzarvandi I'm not entirely sure if Laravel 5.1 supports File Responses but you can try to `return response()->file($pathToFile)`. If this doesn't work try `return response()->download($pathToFile, $name, ['Content-Type' => 'application/pdf', 'Content-Disposition' => "inline; filename=\"{$name}\""]);` What you are doing here is modifying the Content-Disposition header, so that the browser will display the file rather than try to download it. – tamrat Feb 21 '20 at 09:55
Undefined variable: pathToFile – kianoosh Azarvandi Feb 21 '20 at 10:28
The file is being served through `Storage::disk('private')` and the path is inside private folder which is not accessible without serving it using `Storage::disk('private')` – kianoosh Azarvandi Feb 21 '20 at 10:33
