How do you make laravel 7 api authentication with passport like a master

#php #laravel #authentication #api

(I wrote the package for it , if you want to contribute or make your life easy and use the authentication in your project very fast you can use it github)
Today we want to make a Laravel Api authentication
Follow the steps below to make your application authentication and authorization

Step one

They are some clear commands that you should do them

composer require laravel/passport
php artisan migrate
php artisan passport:install

Step two

Change Gurds in config/auth.php like this

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

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

Step three

app/User.php

<?php

namespace App;

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

class User extends Authenticatable {
    use Notifiable, HasApiTokens;

    /**
     * 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',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];
}

Step four

app/Repositories/User/UserRepositoryInterface.php

<?php

namespace App\Repositories\User;

use Illuminate\Http\Request;

interface UserRepositoryInterface {
    public function register(Request $request);
    public function login(Request $request);
    public function refreshToken(Request $request);
    public function details();
    public function logout(Request $request);
    public function response($data, int $statusCode);
    public function getTokenAndRefreshToken(string $email, string $password);
    public function sendRequest(string $route, array $formParams);
    public function getOClient();
}

Step five

create app/Repositories/User/UserRepository.php

<?php

namespace App\Repositories\User;

use App\User;
use GuzzleHttp\Client;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Laravel\Passport\Client as OClient;

    const UNAUTHORISED_STATUS_CODE = 401;
    const BASE_URL = "http://mylemp-nginx";

    public function __construct(Client $client) {
        $this->http = $client;
    }

    public function register(Request $request) {
        $email = $request->email;
        $password = $request->password;
        $input = $request->all();
        $input['password'] = bcrypt($input['password']);
        User::create($input);
        $response = $this->getTokenAndRefreshToken($email, $password);
        return $this->response($response["data"], $response["statusCode"]);
    }

    public function login(Request $request) {

            $response = $this->getTokenAndRefreshToken($email, $password);
            $data = $response["data"];
            $statusCode =  $response["statusCode"];
        } else {
            $data = ['error'=>'Unauthorised'];
            $statusCode =  self::UNAUTHORISED_STATUS_CODE;
        }

        return $this->response($data, $statusCode);
    }

    public function refreshToken(Request $request) {
        if (is_null($request->header('Refreshtoken'))) {
            return $this->response(['error'=>'Unauthorised'], self::UNAUTHORISED_STATUS_CODE);
        }

        $refresh_token = $request->header('Refreshtoken');
        $Oclient = $this->getOClient();
        $formParams = [ 'grant_type' => 'refresh_token',
                        'refresh_token' => $refresh_token,
                        'client_id' => $Oclient->id,
                        'client_secret' => $Oclient->secret,
                        'scope' => '*'];

        return $this->sendRequest("/oauth/token", $formParams);
    }

    public function details() {
        $user = Auth::user();
        return $this->response($user, self::SUCCUSUS_STATUS_CODE);
    }

    public function logout(Request $request) {
        $request->user()->token()->revoke();
        return $this->response(['message' => 'Successfully logged out'], self::SUCCUSUS_STATUS_CODE);
    }

    public function response($data, int $statusCode) {
        $response = ["data"=>$data, "statusCode"=>$statusCode];
        return $response;
    }

    public function getTokenAndRefreshToken(string $email, string $password) {
        $Oclient = $this->getOClient();
        $formParams = [ 'grant_type' => 'password',
                        'client_id' => $Oclient->id,
                        'client_secret' => $Oclient->secret,
                        'username' => $email,
                        'password' => $password,
                        'scope' => '*'];

        return $this->sendRequest("/oauth/token", $formParams);
    }

    public function sendRequest(string $route, array $formParams) {
        try {
            $url = self::BASE_URL.$route;
            $response = $this->http->request('POST', $url, ['form_params' => $formParams]);

            $statusCode = self::SUCCUSUS_STATUS_CODE;
            $data = json_decode((string) $response->getBody(), true);
        } catch (ClientException $e) {
            echo $e->getMessage();
            $statusCode = $e->getCode();
            $data = ['error'=>'OAuth client error'];
        }

        return ["data" => $data, "statusCode"=>$statusCode];
    }

    public function getOClient() {
        return OClient::where('password_client', 1)->first();
    }
}

    public function rules() {
        return [
            'email' => 'required|email',
            'password' => 'required',
          ];
    }

    protected function failedValidation(Validator $validator) {
        throw new HttpResponseException(response()->json($validator->errors(), self::UNPROCESSABLE_ENTITY));
    }
}

Step seven

            'name' => 'required',
            'email' => 'required|email|unique:users',
            'password' => 'required',
            'c_password' => 'required|same:password',
          ];
    }

    protected function failedValidation(Validator $validator) {
        throw new HttpResponseException(response()->json($validator->errors(), self::UNPROCESSABLE_ENTITY));
    }
}

Step eight

     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot() {
        //
    }
}

Step nine

<?php

namespace App\Providers;

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

    const SUCCUSUS_STATUS_CODE = 200;
    const UNAUTHORISED_STATUS_CODE = 401;

    public function __construct(UserRepositoryInterface $userRepository) {
        $this->userRepository = $userRepository;
    }

    public function login(UserLoginRequest $request) {
        $response = $this->userRepository->login($request);
        return response()->json($response["data"], $response["statusCode"]);
    }

routes/api.php

<?php

use Illuminate\Support\Facades\Route;

Route::post('login', 'UserController@login');
Route::post('register', 'UserController@register');

Route::group(['middleware' => ['auth:api']], function () {
    Route::post('logout', 'UserController@logout');
    Route::post('details', 'UserController@details');
});

lets test it

Open the postman and add it to your header

Accept : application/json

And then do sth like this
