I have created API Authentication using laravel passport.When authorization token get wrong its send me an error "Route [login] not defined"

Question

I have created API Authentication using laravel passport.When authorization token get wrong its send me an error "Route [login] not defined" although I need JSON response like "unauthorized 401"

This is api.php Here users/authenticate is a login route but when I use other routes which are inside the auth:api middleware. If token will be wrong its send me an error "Route [login] not defined" but I dont need this error. I need JSON error like {error:unauthorized , code:401}.

<?php

use Illuminate\Http\Request;

/*
|--------------------------------------------------------------------------
| API Routes
|--------------------------------------------------------------------------
|
| Here is where you can register API routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| is assigned the "api" middleware group. Enjoy building your API!
|
*/
    Route::post('users/authenticate', ['uses' => 'Auth\LoginController@login']);






Route::group(['middleware' => ['auth:api']], function() {    
    /* Business details for New register business, get all business, update business, get single business */
    Route::post('businesses/create', ['uses' => 'Business\BusinessController@businessRegister']);
    Route::post('businesses/{id}', ['uses' => 'Business\BusinessController@businessUpdate']);
    Route::get('businesses/{id}', ['uses' => 'Business\BusinessController@businessGet']);
    Route::get('businesses-info/{id}', ['uses' => 'Business\BusinessController@businessInfoGet']);

});

this is auth.php

'guards' => [
    'web' => [
        'driver' => 'session',
        'provider' => 'users',
    ],

    'api' => [
        'driver' => 'passport',
        'provider' => 'users',
    ],
],

This is AuthServiceProvider.php

<?php

namespace App\Providers;

use Illuminate\Support\Facades\Gate;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;
use Laravel\Passport\Passport;

class AuthServiceProvider extends ServiceProvider
{
    /**
     * The policy mappings for the application.
     *
     * @var array
     */
    protected $policies = [
        'App\Model' => 'App\Policies\ModelPolicy',
    ];

    /**
     * Register any authentication / authorization services.
     *
     * @return void
     */
    public function boot()
    {
        $this->registerPolicies();

        Passport::routes();
    }
}

This is app.php

'providers' => [

        /*
         * Laravel Framework Service Providers...
         */
        Illuminate\Auth\AuthServiceProvider::class,

        App\Providers\EventServiceProvider::class,
        App\Providers\RouteServiceProvider::class,
        Laravel\Passport\PassportServiceProvider::class,

    ],

This is Handler.php

<?php

namespace App\Exceptions;

use Exception;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;
use Illuminate\Auth\AuthenticationException;
class Handler extends ExceptionHandler
{
    /**
     * A list of the exception types that are not reported.

     * @var array
     */
    protected $dontReport = [
        //
    ];

    /**
     * A list of the inputs that are never flashed for validation exceptions.
     *
     * @var array
     */
    protected $dontFlash = [
        'password',
        'password_confirmation',
    ];

    /**
     * Report or log an exception.
     *
     * @param  \Exception  $exception
     * @return void
     */
    public function report(Exception $exception)
    {
        parent::report($exception);
    }

    /**
     * Render an exception into an HTTP response.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Exception  $exception
     * @return \Illuminate\Http\Response
     */
    public function render($request, Exception $exception)
    {
        return parent::render($request, $exception);
    }


}

Answer 1

I was facing same issue then I added Auth::routes(); at the end of web.php then it started working.

I don't know if it is correct or not but it solved the issue.

Another reason can be that you are not sending laravel required headers i.e.

'accept' => 'application/json', //it tells server to send only json response
'content-type' => 'application/json'   // it tells front-end app to send data in json format

Hope it can solve your problem

Answer 2

You need to customize your code and add the following method in the code:

protected function unauthenticated($request, AuthenticationException $exception)
{
    return $request->expectsJson()
           ? response()->json(['message' => 'Unauthenticated.'], 401)
           : redirect()->guest(route('users/authenticate'));
}

This will work for you
