            ]);
        }
    
        //LOGIN USER

            }
            //return responce

        }
    
    
        //logout user
        public function logOut(Request $request)
        {
            auth()->user()->token()->delete();
            return response(['message' => 'logout success']);
        }
    
        //get user details
        public function user()
        {
            return response(['user' => auth()->user()], 200);
        }
    
        public function Update(Request $request)
        {
            $attrs = $request->validate(['name' => 'required|String']);
    
            $image = $this->saveImage($request->image, 'profile');
    
            auth()->user()->update([
    
                'name' => $attrs['name'],
                'image' => $image
            ]);
    
            return response([
                'message' => 'user updated',
                'user' => auth()->user()
            ], 200);
    
        }
    
    }

am expecting to get the users profile from the database but the error route login not defined keeps on popping up

this is the route am testing

Route::get('/user', [Authcontroller::class, 'user']);

Solution

This error usually occurs when you try to access a route that requires authorization without a token and your login route is not defined. If you are developing an API, you must inform laravel about this by adding the accept application/json in your request headers. Then laravel will give the correct 401 response.

Accordingly, there is something wrong with your authorization.
