One of the most common things is to upload files such as images, pdf, etc. but usually, people forget the importance of protecting URLs when downloading our files.

Let's take an example, if we need to download something important like a contract and your URL is visible and accessible from anywhere, you would be exposing sensitive information to anyone who may have access to it.

Let's begin

For this example, I'll be using a small table of products like this

Now, we can define the fields in the Product model

class Product extends Model
{
    protected $fillable = [
        'name', 
        'uuid', 
        'price',
        'image'
    ];
}

The next step is to create the route to download the files, open routes/web.php file and add

Route::get('products/{uuid}/download', 'ProductController@download')->name('products.download');

In the ProductController, we need to define the download function

public function download($uuid)
{
    $product = Product::where('uuid', $uuid)->firstOrFail();
    $pathToFile = storage_path('app/public/products/' . $product->image);
    return response()->download($pathToFile);
}

Note: We need to generate a UUID when we store a new product, to generate a UUID you can use this article Generate UUID

Alright, now we need to go to our blade file and the route like this

<a href="{{ route('products.download', $product->uuid) }}">{{ $product->image }}</a>

This way we can protect our files.
