Laravel Passport Route [login] not defined

Question

i use Laravel passport for auth

in route api.php

Route::get(\'/todos\', function(){
  return \'hello\';
})->middleware(\'auth:api\');

Answer 1

Use Postman and set the Header Accept: application/json otherwise Laravel Passport would never know it's an API client and thus redirect to a /login page for the web.

see below image to see where to set the accept parameter:

Answer 2

Check Your Header Request to put

Authorization = Bearer {your token}

Answer 3

You also have to add another header Key: X-Requested-With and value: XMLHttpRequest

Answer 4

Did you enter above-mentioned URL directly in browser search bar? If you did its wrong way because you also need to enter API token with your request__!!

To check either request includes token or not make your own middleware.

Command to create Middleware

php artisan make:middleware CheckApiToken

https://laravel.com/docs/5.6/middleware

change middleware handle method to

public function handle($request, Closure $next)
{
    if(!empty(trim($request->input('api_token')))){

        $is_exists = User::where('id' , Auth::guard('api')->id())->exists();
        if($is_exists){
            return $next($request);
        }
    }
        return response()->json('Invalid Token', 401);
}

Like This Your Url should be like this

http://localhost:8000/api/todos?api_token=API_TOKEN_HERE

Answer 5

In the following of @Eki answer,

This error is because you didn't set "Accept" field in your headers.

To avoid this error, add a middleware with priority to Authenticate to check that:

1. add an extra middleware with below handler

   public function handle($request, Closure $next)
   {
       if(!in_array($request->headers->get('accept'), ['application/json', 'Application/Json']))
           return response()->json(['message' => 'Unauthenticated.'], 401);
   
       return $next($request);
   }
   

2. set priority in app/Http/Kernel.php

   protected $middlewarePriority = [
       ...
       \App\Http\Middleware\MyMiddleware::class, // new middleware
       \App\Http\Middleware\Authenticate::class,
       ...
   ];
   

3. add new middleware to your route

   Route::get('/todos', function(){
       return 'hello';
   })->middleware('MyMiddleware', 'auth:api');

You also have to add another header Key: Accept and value: application/json
