JWT Auth Guard is a Laravel & Lumen Package that lets you use jwt as your driver for authentication guard in your application.

The Guard uses tymon/jwt-auth package for authentication and token handling.

Requirements

• Laravel or Lumen Installation.
• tymon/jwt-auth ^1.0@dev Package Setup and Config'd.

Pre-Installation

First install and setup tymon/jwt-auth package.

$ composer require tymon/jwt-auth:^1.0@dev

Once done, config it and then install this package.

Install

Via Composer

$ composer require irazasyed/jwt-auth-guard

Add the Service Provider

Laravel

Open config/app.php and, to your providers array at the bottom, add:

Irazasyed\JwtAuthGuard\JwtAuthGuardServiceProvider::class

Lumen

Open bootstrap/app.php and register the service provider:

$app->register(Irazasyed\JwtAuthGuard\JwtAuthGuardServiceProvider::class);

Usage

Open your config/auth.php config file and in place of driver under any of your guards, just add the jwt-auth as your driver and you're all set. Make sure you also set provider for the guard to communicate with your database.

Setup Guard Driver

// config/auth.php
'guards' => [
    'api' => [
        'driver' => 'jwt-auth',
        'provider' => 'users'
    ],
    
    // ...
],

'providers' => [
    'users' => [
        'driver' => 'eloquent',
        'model'  => App\User::class,
    ],
],

Middleware Usage

Middleware protecting the route:

Route::get('api/content', ['middleware' => 'auth:api', 'uses' => 'ContentController@content']);

Middleware protecting the controller:

<?php

namespace App\Http\Controllers;

class ContentController extends Controller
{
    public function __construct() 
    {
        $this->middleware('auth:api');
    }
}

Note: The above example assumes you've setup a guard with the name api whose driver is jwt-auth in your config/auth.php file as explained in "Setup Guard Driver" section above.

The following usage examples assume you've setup your default auth guard to the one which uses the jwt-auth driver.

You can also explicitly define the guard before making calls to any of methods by just prefixing it with Auth::guard('api').

Example: Auth::guard('api')->user()

Attempt To Authenticate And Return Token

// This will attempt to authenticate the user using the credentials passed and returns a JWT Auth Token for subsequent requests.
$token = Auth::attempt(['email' => 'user@domain.com', 'password' => '123456']);

Authenticate Once By ID

if(Auth::onceUsingId(1)) {
    // Do something with the authenticated user
}

Authenticate Once By Credentials

if(Auth::once(['email' => 'user@domain.com', 'password' => '123456'])) {
    // Do something with the authenticated user
}

Validate Credentials

if(Auth::validate(['email' => 'user@domain.com', 'password' => '123456'])) {
    // Credentials are valid
}

Check User is Authenticated

if(Auth::check()) {
    // User is authenticated
}

Check User is a Guest

if(Auth::guest()) {
    // Welcome guests!
}

Logout Authenticated User

Auth::logout(); // This will invalidate the current token and unset user/token values.

Generate JWT Auth Token By ID

$token = Auth::generateTokenById(1);

echo $token;

Get Authenticated User

Once the user is authenticated via a middleware, You can access its details by doing:

$user = Auth::user();

You can also manually access user info using the token itself:

$user = Auth::setToken('YourJWTAuthToken')->user();

Get Authenticated User's ID

$userId = Auth::id();

Refresh Expired Token

Though it's recommended you refresh using the middlewares provided with the package, but if you'd like, You can also do it manually with this method.

Refresh expired token passed in request:

$token = Auth::refresh();

Refresh passed expired token:

Auth::setToken('ExpiredToken')->refresh();

Invalidate Token

Invalidate token passed in request:

$forceForever = false;
Auth::invalidate($forceForever);

Invalidate token by setting one manually:

$forceForever = false;
Auth::setToken('TokenToInvalidate')->invalidate($forceForever);

Get Token

$token = Auth::getToken(); // Returns current token passed in request.

Get Token Payload

This method will decode the token and return its raw payload.

Get Payload for the token passed in request:

$payload = Auth::getPayload();

Get Payload for the given token manually:

$payload = Auth::setToken('TokenToGetPayload')->getPayload();
