Laravel 5.7 how to serve files images privately

controller_onerouteForevery.php

<?php
public function getCompaniesLogo($file) {
       // know you can have a mapping so you dont keep the sme names as in local (you can not precsise the same structor as the storage, you can do anything)

       // any permission handling or anything else

       $filePath = config('fs.gallery').DIRECTORY_SEPARATOR.$file; // here in place of just using 'gallery', i'm setting it in a config file

       // here i'm getting only the path from the root (this way we can change the root later) / also we can change the structor on the store itself, change in one place config.fs.
      // $filePath = Storage::url($filePath); <== this doesn't work don't use
      // check for existance
       if (!Storage::disk('local')->exists($filePath)){ // as mentionned precise relatively to storage disk root (this one work well not like Storage:url()
       abort('404');
       } 

       // if there is parameters [you can change the files, depending on them. ex serving different content to different regions, or to mobile and desktop …etc] // repetitive things can be handled through helpers [make helpers]

       return response()->file(storage_path('app'.DIRECTORY_SEPARATOR.($filePath))); // the response()->file() will add the necessary headers in our place
 }

controller_wildcardroute.php

<?php
public function fileStorageServe($file) {
     // know you can have a mapping so you dont keep the sme names as in local (you can not precsise the same structor as the storage, you can do anything)

     // any permission handling or anything else

     // we check for the existing of the file 
     if (!Storage::disk('local')->exists($filePath)){ // note that disk()->exists() expect a relative path, from your the disk root path. so in our example we pass directly the path (/…/laravelProject/storage/app) is the default one (referenced with the helper storage_path('app')
     abort('404'); // we redirect to 404 page if it doesn't exist
     } 
     //file exist let serve it 

     // if there is parameters [you can change the files, depending on them. ex serving different content to different regions, or to mobile and desktop …etc] // repetitive things can be handled through helpers [make helpers]

     return response()->file(storage_path('app'.DIRECTORY_SEPARATOR.($filePath))); // the response()->file() will add the necessary headers in our place (no headers are needed to be provided for images (it's done automatically) expected hearder is of form => ['Content-Type' => 'image/png'];

     // big note here don't use Storage::url() // it's not working correctly.
