{
    $fileFullPath = Storage::disk('local')->path('folder1/a.png');
    $fileUrl = Storage::disk('local')->url('app/folder1/a.png');
    $storage_path = storage_path('app/folder1/a.png');

    return view('email.fileDownload')->with([
        'fileFullPath' => $fileFullPath,
        'fileUrl' => $fileUrl,

In view : email.fileDownload

<div>
    <p>  asset($fileUrl) ==> {{asset($fileUrl)}}</p>
    <img src="{{asset($fileUrl)}}"/>
</div>
<div>
    <p>  url($fileUrl) ==> {{url($fileUrl)}}</p>
    <img src="{{url($fileUrl)}}"/>
</div>
<div>
    <p>  storage_path($fileUrl) ==> {{storage_path($fileUrl)}}</p>

</div>

the result is :

Answer 1

Go to config/filesystems add this array

'public_site' => [
            'driver' => 'local',
            'root' => public_path('storage'),
            'url' => env('APP_URL').'/storage',
            'visibility' => 'public',
        ]

then your function could be like this

public function viewStorageFiles()
{
    $fileFullPath = Storage::disk('public_site')->path('folder1/a.png');
    $fileUrl = Storage::disk('public_site')->url('app/folder1/a.png');
    $public_path = public_path('storage/app/folder1/a.png');

    return view('email.fileDownload')->with([
        'fileFullPath' => $fileFullPath,
        'fileUrl' => $fileUrl,
        'storage_path' => $public_path,
        ]);
}

Answer 2

There could be many answers to this!

You could create a symbolic link from "public/storage" to "storage/app/public" using the following command:

php artisan storage:link

Above command will map your storage/app/public directory to public directory.

Now let's consider you have user1.jpg and user2.jpg files in your storage/app/public directory, you can access them in the following way:

http://your-domain.com/storage/user1.jpg
http://your-domain.com/storage/user2.jpg

* Updated my answer based on your comment: *

You can return a file response from a route that is protected by some middleware!

For example - following route returns file response from storage/app/uploads directory that is not accessible publicly:

Route::get('storage/{file}', function ($file) {
    $path = storage_path('app' . DIRECTORY_SEPARATOR . 'uploads' . DIRECTORY_SEPARATOR . $file);
    return response()->file($path);
});

You could secure above route in anyway and use it in your views..

I hope that helped..
