In this tutorial, we will see how to use Laravel passport authentication in your Laravel application.

Let’s see how to setup and configure Laravel Passport for API authentication and RESTful APIs in a Laravel application.

Creating a New Project

     Shell 
   
 x 
         
composer create-project --prefer-dist laravel/laravel passport

Install Package

     Shell 
   
xxxxxxxxxx
 
composer require laravel/passport

Service Provider

You need to add Service Provider in the config/app.php file. So, open the file and add the Service Provider in the providers array.

     PHP 
   
xxxxxxxxxx
 
'providers' => [
    ....
    Laravel\Passport\PassportServiceProvider::class,
]

Migration and Installation

Set up database credentials in the .env file. Run the migration command to migrate schemas to your database.

     Shell 
   
xxxxxxxxxx
 
php artisan migrate

Next, it is required to install passport using the command below. It will generate encryption keys required to generate secret access tokens.

     PHP 
   
xxxxxxxxxx
 
php artisan passport:install

Passport Configure

Add Laravel\Passport\HasApiTokens trait to your User model. It will provide few helper methods.

     Java 
   
xxxxxxxxxx
 
<?php
 
namespace App;
 
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Laravel\Passport\HasApiTokens;
 
class User extends Authenticatable
{
    use HasApiTokens, Notifiable;
 
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password',
    ];
 
    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
}

Add Passport::routes method in the boot method of your AuthServiceProvider. It will generate necessary routes. This is how the app/Providers/AuthServiceProvider.php will look like after changes.

     Java 
   
xxxxxxxxxx
 
<?php
 
namespace App\Providers;
 
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();
    }
}

In the config/auth.php file, set driver to the passport.

     Java 
   
xxxxxxxxxx
 
return [
    ....
 
    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],
 
        'api' => [
            'driver' => 'passport',
            'provider' => 'users',
        ],
    ],
 
    ....
]

Create Route

Add routes in the routes/api.php file.

     Java 
   
xxxxxxxxxx
 
Route::post('login', 'PassportController@login');
Route::post('register', 'PassportController@register');
 
Route::middleware('auth:api')->group(function () {
    Route::get('user', 'PassportController@details');
 
    Route::resource('products', 'ProductController');
});

Create Controller for Authentication

Create Passport Controller by running the following command.

     Shell 
   
xxxxxxxxxx

php artisan make:controller PassportController

Copy the contents below to app/Http/Controllers/PassportController.php

     Java 
   
 
  
    
 
      
 
     
 
      
 
     
 
     
 
    
xxxxxxxxxx
 
          
 
         
 
          
 
         

              
          
<?php
 
namespace App\Http\Controllers;
 
use App\User;
use Illuminate\Http\Request;
 
class PassportController extends Controller
{
    /**
     * Handles Registration Request
     *
     * @param Request $request
     * @return \Illuminate\Http\JsonResponse
     */
    public function register(Request $request)
    {
        $this->validate($request, [
            'name' => 'required|min:3',
            'email' => 'required|email|unique:users',
            'password' => 'required|min:6',
        ]);
 
        $user = User::create([
            'name' => $request->name,
            'email' => $request->email,
            'password' => bcrypt($request->password)
        ]);
 
        $token = $user->createToken('TutsForWeb')->accessToken;
 
        return response()->json(['token' => $token], 200);
    }
 
    /**
     * Handles Login Request
     *
     * @param Request $request
     * @return \Illuminate\Http\JsonResponse
     */
    public function login(Request $request)
    {
        $credentials = [
            'email' => $request->email,
            'password' => $request->password
        ];
 
        if (auth()->attempt($credentials)) {
            $token = auth()->user()->createToken('TutsForWeb')->accessToken;
            return response()->json(['token' => $token], 200);
        } else {
            return response()->json(['error' => 'UnAuthorised'], 401);
        }
    }
 
    /**
     * Returns Authenticated User Details
     *
     * @return \Illuminate\Http\JsonResponse
     */
    public function details()
    {
        return response()->json(['user' => auth()->user()], 200);
    }
}
 
      
 
     

Testing

Now thar our logic is complete, let’s start testing. We will be testing it on PHP development server, but you can use virtual host if you want. Run the following command to serve the application on the PHP development server.

     Shell 
   
xxxxxxxxxx

php artisan serve

Now, let’s test our API endpoints using an API testing tool like Postman.
