Auth::check() not working Laravel 5.5 - laravel-5.5

Question

In my model i have a method
public function newUserUpload(string $save_path){
$this->photo_moderation_src = $save_path;
if(Auth::check()){
$this->user_id = Auth::id();
}
$this->save();
return null;
}
After authorization i try to upload file but the record in the database is created without user_id. At the same time the authorization check in my blade is working correctly.
#if (!Auth::check())
<li>Auth</li>
#else
<li>Exit</li>
#endif
Could this be due to the fact that I use vueJs + Laravel api routes?
Route::middleware('api')->group(function(){
Route::post('/upload/', 'CompgenApiController#userUpload');
Route::post('/reupload/', 'CompgenApiController#moderationReupload');
});

Answer 1

use Auth;
or use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Auth;
if (Auth::check()) {
// The user is logged in...
}
or
if (\Illuminate\Support\Facades\Auth::check()) {
// The user is logged in...
}
for user id u can use Auth::user()->id or something else in users table, like:
Auth::user()->hasRole, Auth::user()->registrationCompleted
public function newUpload(string $save_path){
if(!Auth::check()){ return false }
// if(!Auth::user()->registrationCompleted){ return false }
// other Security measures
$newUpload = new Pic(); // pics table in dataBase
$newUpload->photo_moderation_src = $save_path;
$newUpload->user_id = Auth::user()->id;
$newUpload->save();
return true;
}
