REST-API-in-Laravel-with-Passport-Authentication

Hi Guys. This example illustrates how to create a RESTful API using Laravel Passport Authentication. In this example, we will see how to use laravel passport authentication in your Laravel application. When a user login via API, a token is generated and sent to the user which is used for authentication purposes.

I will explain step by step how to create rest api using passport in laravel 5.7

Steps :

• Install Laravel 5.7

• Create Database

• Install Passport

• Configure Laravel Passport

• Add Product Table and Model

• Create API Routes

• Create Controller Files

Installation Step by Step:

1- Install Laravel 5.7:

> composer create-project --prefer-dist laravel/laravel rest-api

2- Create a Database in MySQL (choose a name, for example: rest-api) then create a new .env file

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=rest-api
DB_USERNAME=root
DB_PASSWORD=

3- Install Passport

- We need to install Laravel Passport package via the composer dependency manager

  > composer require laravel/passport

- After successfully installing passport package, we create new passport tables in our database. 

  > php artisan migrate

- Next, we need to install passport to create token keys for security. 

 > php artisan passport:install

4- Passport Configuration:

- In this step, we configure model, service provider and auth file.

- In model app/User.php , we add HasApiTokens class of Passport

```
<?php

    namespace App;

    use Illuminate\Notifications\Notifiable;
    use Illuminate\Contracts\Auth\MustVerifyEmail;
    use Laravel\Passport\HasApiTokens;
    use Illuminate\Foundation\Auth\User as Authenticatable;

    class User extends Authenticatable implements MustVerifyEmail {

        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',
        ];
    }

    ```

- In app/Providers/AuthServiceProvider.php, we add "Passport::routes()",

    ```
    <?php
    
        namespace App\Providers;

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

        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 config/auth.php, we add api auth configuration

    ```
    <?php

        return [

            .....
            'guards' => [

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

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

    ```

5- Add Product Table and Model:

• Next, we need to create migration for products table using Laravel 5.7 php artisan command,

  php artisan make:migration create_products_table

• After this command you will find one file in following path database/migrations

   <?php
  
     use Illuminate\Support\Facades\Schema;
     use Illuminate\Database\Schema\Blueprint;
     use Illuminate\Database\Migrations\Migration;
  
     class CreateProductsTable extends Migration {
     /**
         * Run the migrations.
         *
         * @return void
         */
  
         public function up()
         {
             Schema::create('products', function (Blueprint $table) {
  
                 $table->increments('id');
                 $table->string('name');
                 $table->text('detail');
                 $table->timestamps();
  
             });
         }
  
         /**
         * Reverse the migrations.
         *
         * @return void
         */
  
         public function down()
         {
             Schema::dropIfExists('products');
         }
  
     }
