Laravel Sanctum

What is Laravel Sanctum ? Laravel Sanctum provides a featherweight authentication system for SPAs (single page applications), mobile applications, and simple, token based APIs. Sanctum allows each user of your application to generate multiple API tokens for their account. These tokens may be granted abilities / scopes which specify which actions the tokens are allowed to perform..

You have to just follow a few steps to get following web services

Login API

Details API

---

Step 1: setup database in .env file

DB_DATABASE=youtube
DB_USERNAME=root
DB_PASSWORD= redhat@123

Step 2:Install Laravel Sanctum.

composer require laravel/sanctum

Step 3:Publish the Sanctum configuration and migration files .

php artisan vendor:publish --provider="Laravel\Sanctum\SanctumServiceProvider"

Step 4:Run your database migrations.

php artisan migrate

Step 5:Add the Sanctum's middleware.

../app/Http/Kernel.php

use Laravel\Sanctum\Http\Middleware\EnsureFrontendRequestsAreStateful;

...

    protected $middlewareGroups = [
        ...

        'api' => [
            EnsureFrontendRequestsAreStateful::class,
            'throttle:60,1',
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],
    ];

    ...
],

Step 6:To use tokens for users.

use Laravel\Sanctum\HasApiTokens;

class User extends Authenticatable
{
    use HasApiTokens, Notifiable;
}

Step 7:Let's create the seeder for the User model

php artisan make:seeder UsersTableSeeder

Step 8:Now let's insert as record

use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Hash;
...
...
DB::table('users')->insert([
    'name' => 'John Doe',
    'email' => 'john@doe.com',
    'password' => Hash::make('password')
]);

Step 9:To seed users table with user

php artisan db:seed --class=UsersTableSeeder

Step 10: create a controller nad /login route in the routes/api.php file:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\User;
use Illuminate\Support\Facades\Hash;
class UserController extends Controller
{
    // 

    function index(Request $request)
    {
        $user= User::where('email', $request->email)->first();
        // print_r($data);
            if (!$user || !Hash::check($request->password, $user->password)) {
                return response([
                    'message' => ['These credentials do not match our records.']
                ], 404);
            }
        
             $token = $user->createToken('my-app-token')->plainTextToken;
        
            $response = [
                'user' => $user,
                'token' => $token
            ];
        
             return response($response, 201);
    }
}

Step 11: Test with postman, Result will be below

{
    "user": {
        "id": 1,
        "name": "John Doe",
        "email": "john@doe.com",
        "email_verified_at": null,
        "created_at": null,
        "updated_at": null
    },
    "token": "AbQzDgXa..."
}

Step 11: Make Details API or any other with secure route

Route::group(['middleware' => 'auth:sanctum'], function(){
    //All secure URL's

    });


Route::post("login",[UserController::class,'index']);

Laravel passport

What is Passport? APIs typically use tokens to authenticate users and do not maintain session state between requests. Laravel makes API authentication a breeze using Laravel Passport, which provides a full OAuth2 server implementation for your Laravel application development in a matter of minutes.

You have to just follow a few steps to get following web services

Login API

Register API

Details API

Getting Started

Step 1: Install Package

composer require laravel/passport

open config/app.php file and add service provider.

config/app.php
'providers' =>[
Laravel\Passport\PassportServiceProvider::class,
],

Step 2: Run Migration and Install

php artisan migrate
php artisan passport:install

Step 3: Passport Configuration app/User.php

<?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',
];
}

app/Providers/AuthServiceProvider.php

<?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(); 
    } 
}

Step 4 :config/auth.php

<?php
return [
'guards' => [ 
        'web' => [ 
            'driver' => 'session', 
            'provider' => 'users', 
        ], 
        'api' => [ 
            'driver' => 'passport', 
            'provider' => 'users', 
        ], 
    ],

Step 5: Create API Route

<?php
/*
|--------------------------------------------------------------------------
| 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('login', 'API\UserController@login');
Route::post('register', 'API\UserController@register');
Route::group(['middleware' => 'auth:api'], function(){
Route::post('details', 'API\UserController@details');
});

Step 6: Create the Controller

<?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 UserController extends Controller 
{
public $successStatus = 200;
/** 
     * login api 
     * 
     * @return \Illuminate\Http\Response 
     */ 
    public function login(){ 
        if(Auth::attempt(['email' => request('email'), 'password' => request('password')])){ 
            $user = Auth::user(); 
            $success['token'] =  $user->createToken('MyApp')-> accessToken; 
            return response()->json(['success' => $success], $this-> successStatus); 
        } 
        else{ 
            return response()->json(['error'=>'Unauthorised'], 401); 
        } 
    }
/** 
     * Register api 
     * 
     * @return \Illuminate\Http\Response 
     */ 
    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('MyApp')-> accessToken; 
        $success['name'] =  $user->name;
return response()->json(['success'=>$success], $this-> successStatus); 
    }
/** 
     * details api 
     * 
     * @return \Illuminate\Http\Response 
     */ 
    public function details() 
    { 
        $user = Auth::user(); 
        return response()->json(['success' => $user], $this-> successStatus); 
    } 
}

Step 7: Run

php artisan serve
