Download Fresh Laravel 5.8 Setup

Download Laravel fresh setup using below command, Open command prompt and Type the below command:

composer create-project --prefer-dist laravel/laravel larapassport

Install Passport Package In Laravel

In this step run the below command and install passport package :

composer require laravel/passport

After successfully install laravel passport, register providers. Open config/app.php . and put the bellow code :

  // config/app.php

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

Before you run migration command , go to the app/providers/AppServiceProvider.php and put the two line of code inside a boot method :

 Use Schema; 
 public function boot() { 
 Schema::defaultStringLength(191); 
 }

Run Migration and Install Laravel Passport

We need to do migration using bellow command. This command create tables in database :

php artisan migrate

We need to install laravel generate passport encrption keys. This command will create the encryption keys needed to generate secure access tokens . like secret key and secret id.

php artisan passport:install

Laravel Passport Configuration

Configuration some file . Next open App/User.php file and put the below code on App/User.php File

<?php
namespace App;
use Laravel\Passport\HasApiTokens;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
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',
];
}

Next Register passport routes in App/Providers/AuthServiceProvider.php, Go to App/Providers/AuthServiceProvider.php and put this => Register Passport::routes(); inside of boot method :

<?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();
    }
}

config/auth.php

Next go ot config/auth.php and Change the api driver to session to passport . Put this code ‘driver’ => ‘passport’, in api :

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

Create API Route

In this step,we will create api routes, go to api.php inside route folder and create below routes here :

 Route::prefix('v1')->group(function(){
  Route::post('login', 'Api\AuthController@login');
  Route::post('register', 'Api\AuthController@register');
  Route::group(['middleware' => 'auth:api'], function(){
  Route::post('getUser', 'Api\AuthController@getUser');
  });
 });

Create Controller

Now will create a controller name AuthController. Use the below command and create controller :

 php artisan make:controller Api\AuthController

After that we will create some methods in authController :

<?php
namespace App\Http\Controllers\Api;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\User;
use Illuminate\Support\Facades\Auth;
use Validator;
class AuthController extends Controller
{
 public $successStatus = 200;

 public function register(Request $request) {
 $validator = Validator::make($request->all(), [
              'name' => 'required',
              'email' => 'required|email',
              'password' => 'required',
              'c_password' => 'required|same:password',
    ]);
 if ($validator->fails()) {
       return response()->json(['error'=>$validator->errors()], 401);                        }
 $input = $request->all();
 $input['password'] = bcrypt($input['password']);
 $user = User::create($input);
 $success['token'] =  $user->createToken('AppName')->accessToken;
 return response()->json(['success'=>$success], $this->successStatus);
}


public function login(){
if(Auth::attempt(['email' => request('email'), 'password' => request('password')])){
   $user = Auth::user();
   $success['token'] =  $user->createToken('AppName')-> accessToken;
    return response()->json(['success' => $success], $this-> successStatus);
  } else{
   return response()->json(['error'=>'Unauthorised'], 401);
   }
}

public function getUser() {
 $user = Auth::user();
 return response()->json(['success' => $user], $this->successStatus);
 }
} 

 Lets got terminal & run the command :
 php artisan serve
 or 
 http://localhost/blog/public/Api/v1/(here route)

Now Test Rest Api in Postman

Laravel Register Api :

Login Api :

Next Step , we will call getUser api, In this api you have to set two header followning :

 
 Call login or register apis put $accessToken. 
 
 ‘headers’ => [
 ‘Accept’ => ‘application/json’,
 ‘Authorization’ => ‘Bearer ‘.$accessToken,
 
 ] 

Pass header in login / register rest api. it is neccessary to passport authentication in laravel app

Conclusion

Laravel passport – We have successfully install laravel passport package and also configuration passport package in laravel application. Using the laravel passport package we have successfully create rest authentication login api, register api and get user info api.
