I have a question regarding Authentication in Laravel 5.x. I’ve been specifically looking at tymondesigns/jwt-auth and irazasyed/jwt-auth-guard packages to do the JSON web token authentication and token handling in my Laravel application.

I am not using a local database whatsoever, nor do I want to. I have environment variables set up in .env for my API’s URL, USERNAME & PASSWORD. The Guzzle PHP HTTP client is doing the trick just fine connecting and returning data between the API and my application as needed.

However, I need to set up Authentication within my Laravel instance. This is where I run into problems, and the auth is wanting a DB connection…

$token = JWTAuth::attempt($credentials)

Here's the exception:

PDOException in Connector.php line 55: 
SQLSTATE[HY000] [14] unable to open database file
  1. How can I make use of JWT without using a database?
  2. How can I COMPLETELY shut-off database connections within Laravel?

Thanks.


UPDATE:

Using tymon/jwt-auth, I've set things up within the routes, Kernel, Middleware, etc.

I created a "claim" successfully, but I need to create the token by encoding the "payload."

<?php
    $this->username = $request->username;

    $sub = $this->username;
    $iat = time();
    $jti = md5($sub . $iat);
    $aud = env('APP_URL');

    $this->claims = [
        'sub' => $sub,
        'iat' => $iat,
        'exp' => time() + (2 * 7 * 24 * 60 * 60),
        'nbf' => $iat,
        'iss' => 'khill',
        'jti' => $jti,
        'aud' => $aud,
    ];

    $payload = JWTFactory::make($this->claims);
?>

How do I get the custom token?

You should define a custom Authentication Provider and set it in config/jwt.php.


Example of provider

Put this class anywhere you like.

namespace MyNamespace;

use Tymon\JWTAuth\Providers\Auth\AuthInterface;

class MyCustomAuthenticationProvider implements AuthInterface
{
    public function byCredentials(array $credentials = [])
    {
        return $credentials['username'] == env('USERNAME') && $credentials['password'] == env('PASSWORD');
    }

    public function byId($id)
    {
        // maybe throw an expection?
    }

    public function user()
    {
        // you will have to implement this maybe.
    }
}

Example of configuration

In the providers array in config/jwt.php, change this:

'auth' => 'Tymon\JWTAuth\Providers\Auth\IlluminateAuthAdapter',

to this:

'auth' => 'MyNamespace\MyCustomAuthenticationProvider',

Other considerations
  1. Using the env() function anywhere is not good practice. It's better to use it in your config files, and then use the config() function anywhere else.

  2. You may need to reimplement also the User Provider.

php - JWT Authentication in Laravel Without Database, You should define a custom Authentication Provider and set it in config/jwt.php. Example of provider. Put this class anywhere you like. namespace  JWT authentication provides a secure way to transmit data between the client and server using Laravel APIs. In this post, we will look at how we can create a JWT authentication for a Laravel based API. API’s provide a fluent interface to communicate with the different type of services.

JWTAuth::attempt() won't help you with this, because it hits the database for you behind the scenes. You need some other way to check the environment credentials.

Add a custom method to a class somewhere which will do that for you or pass the credentials against the API you are hitting with Guzzle.

Code example:

public function authenticate($username, $password)
{
    if(!$username === env('USERNAME') or !$password === env('PASSWORD')) {
       // return a message that the user could not be authenticated or false.
    }


    // Generate the JWT token here and store it somewhere. 
}

In one of my previous articles, we have learn How to Create REST API With Passport Authentication In Laravel using Laravel passport for REST API authentication. In this article, we will learn to create fully functional restful API with JWT Authentication in Laravel.

As a quick fix I decided to implement the following custom code...

1) Created custom middleware to handle the logic.

class CustomMiddleware

    protected $loginPath = 'login';

    public function handle($request, Closure $next) {
        $logged_in = $request->session()->get('logged_in');

        if (!$logged_in) {
            return redirect()->guest('login')->with('flag','1');
        }

    return $next($request);
    }
}

2) Added a reference to the middleware class.

class Kernel extends HttpKernel
{
    protected $routeMiddleware = [
        'custom' => \App\Http\Middleware\CustomMiddleware::class,
    ];
}

3) Added it to routes.php.

Route::group(['middleware' => ['custom']], function () {
    // Add routes here
}

Comments
  • And despite the horrible examples for creating a custom token by tymondesigns/jwt-auth. What do you suggest @Ruffles? I can create a custom claim easy enough but how do I create the PayLoad, and the actual JWT Token so I can start authenticating Users and not let them access certain pages, etc. I just need something very simple and for some reason it escapes me.
  • You should still generate a token with the facade, but it's useless for the authenticating part.
  • Thank you. Then how do you create the token and what do you do with token once generated to employ it's use?
  • Check the docs or any tutorial that uses a database but instead of getting and saving data to the database, use your env variables or your API with Guzzle.
