Multi Auth with Laravel 5.4 and Passport

Question

I am trying to setup multi auth with Laravel Passport, but it doesn\'t seem to support it. I am using the Password Grant to issue tokens which requires me to pass username/p

Answer 1

I have created a small package for this issue. Here's the link for the complete doc link

But the gist is, whenever a user entity gets logged in, it checks for the guards and providers.

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

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

    'customers' => [
        'driver' => 'passport',
        'provider' => 'customers'
    ],
],

'providers' => [
    'users' => [
        'driver' => 'eloquent',
        'model' => 'App\User',
    ],
    /**
     * This is the important part. You can create as many providers as you like but right now, 
     * we just need the customer
     */
     'customers' => [
         'driver' => 'eloquent',
         'model' => 'App\Customer',
     ],
],

You should have a controller like this:

<?php

namespace App\Http\Controllers\Auth;

use App\Customers\Customer;
use App\Customers\Exceptions\CustomerNotFoundException;
use Illuminate\Database\ModelNotFoundException;
use Laravel\Passport\Http\Controllers\AccessTokenController;
use Laravel\Passport\TokenRepository;
use League\OAuth2\Server\AuthorizationServer;
use Psr\Http\Message\ServerRequestInterface;
use Lcobucci\JWT\Parser as JwtParser;

class CustomerTokenAuthController extends AccessTokenController
{
     /**
      * The authorization server.
      *
      * @var \League\OAuth2\Server\AuthorizationServer
      */
     protected $server;

     /**
      * The token repository instance.
      *
      * @var \Laravel\Passport\TokenRepository
      */
     protected $tokens;

     /**
      * The JWT parser instance.
      *
      * @var \Lcobucci\JWT\Parser
      */
     protected $jwt;

     /**
      * Create a new controller instance.
      *
      * @param  \League\OAuth2\Server\AuthorizationServer  $server
      * @param  \Laravel\Passport\TokenRepository  $tokens
      * @param  \Lcobucci\JWT\Parser  $jwt
      */
     public function __construct(AuthorizationServer $server,
                                 TokenRepository $tokens,
                                 JwtParser $jwt)
     {
         parent::__construct($server, $tokens, $jwt);
     }

     /**
      * Override the default Laravel Passport token generation
      *
      * @param ServerRequestInterface $request
      * @return array
      * @throws UserNotFoundException
      */
     public function issueToken(ServerRequestInterface $request)
     {
         $body = (parent::issueToken($request))->getBody()->__toString();
         $token = json_decode($body, true);

         if (array_key_exists('error', $token)) {
             return response()->json([
                 'error' => $token['error'],
                 'status_code' => 401
             ], 401);
         }

        $data = $request->getParsedBody();

        $email = $data['username'];  

        switch ($data['provider']) {
            case 'customers';

                try {

                 $user = Customer::where('email', $email)->firstOrFail();

                } catch (ModelNotFoundException $e) {
                  return response()->json([
                      'error' => $e->getMessage(),
                      'status_code' => 401
                  ], 401);
                }

                break;

            default :

                try {

                 $user = User::where('email', $email)->firstOrFail();

                } catch (ModelNotFoundException $e) {
                  return response()->json([
                      'error' => $e->getMessage(),
                      'status_code' => 401
                  ], 401);
                }        
        }

        return compact('token', 'user');
    }
}

and the request should be:

POST /api/oauth/token HTTP/1.1
Host: localhost
Content-Type: application/x-www-form-urlencoded
Cache-Control: no-cache

grant_type=password&username=test%40email.com&password=secret&provider=customers

To check in your controller who is the logged in user, you can do:

auth()->guard('customers')->user()
