Laravel Passport Multiple Authentication using Gua

问题:

Can we use laravel passport with different guards to authenticate APIs for two different types of users. For example we have driver app for driver user and vendor app for vendor user. Both have their different models Driver and Vendor. How can we use different guards to authenticate both types of users using Laravel Passport?

Here is an example of auth.php and api.php to start with

config/auth.php

<?php

return [

    /*
    |--------------------------------------------------------------------------
    | Authentication Defaults
    |--------------------------------------------------------------------------
    */

    'defaults' => [
        'guard' => 'web',
        'passwords' => 'users',
    ],

    /*
    |--------------------------------------------------------------------------
    | Authentication Guards
    |--------------------------------------------------------------------------
    */

    'guards' => [

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

        'driver-api' => [
            'driver' => 'passport',
            'provider' => 'drivers',
        ],

        'vendor-api' => [
            'driver' => 'passport',
            'provider' => 'vendors',
        ],
    ],

    /*
    |--------------------------------------------------------------------------
    | User Providers
    |--------------------------------------------------------------------------
    */

    'providers' => [

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

        'drivers' => [
            'driver' => 'eloquent',
            'model' => App\Driver::class,
        ],

        'vendors' => [
            'driver' => 'eloquent',
            'model' => App\Vendor::class,
        ],
    ],

    /*
    |--------------------------------------------------------------------------
    | Resetting Passwords
    |--------------------------------------------------------------------------
    */

    'passwords' => [

        'users' => [
            'provider' => 'users',
            'table' => 'password_resets',
            'expire' => 60,
        ],

        'drivers' => [
            'provider' => 'drivers',
            'table' => 'password_resets',
            'expire' => 60,
        ],

        'vendors' => [
            'provider' => 'vendors',
            'table' => 'password_resets',
            'expire' => 60,
        ],
    ],

];

routes/api.php

<?php

use Illuminate\Http\Request;

/*
|--------------------------------------------------------------------------
| API Routes
|--------------------------------------------------------------------------
*/

Route::group(['namespace' => 'Driver', 'prefix' => 'driver/v1', 'middleware' => 'auth:driver-api'], function() {

    // define your routes here for the "drivers"
});

Route::group(['namespace' => 'Vendor', 'prefix' => 'vendor/v1', 'middleware' => 'auth:vendor-api'], function() {

    // define your routes here for the "vendors"
});

You have to modify this files:

File: vendor\laravel\passport\src\Bridge\UserRepository.php

Copy/Paste getUserEntityByUserCredentials to make a duplicate of it and name it getEntityByUserCredentials

Then, in the new duplicated function, find the below:

$provider = config('auth.guards.api.provider');

And Replace it with:

$provider = config('auth.guards.'.$provider.'.provider');

---

File: vendor\league\oauth2-server\src\Grant\PasswordGrant.php

in : validateUser method add after $username and $password :

$customProvider = $this->getRequestParameter('customProvider', $request);

if (is_null($customProvider)) {
   throw OAuthServerException::invalidRequest('customProvider');
}

And this instead of the original line

$user = $this->userRepository->getEntityByUserCredentials(
    $username,
    $password,
    $this->getIdentifier(),
    $client,
    $customProvider
);

---

After doing this you'll be able to pass an extra key/value pair to your access token request, like for example:

grant_type => password,
client_id => someclientid
client_secret => somesecret,
username => someuser,
password => somepass,
client_scope => *,
provider => driver-api // Or vendor-api

---

I hope this will be helpful for you

I managed to create multiple auths (with laravel/passport) by using a simple middlware.

Step 1: config/auth.php

Add your user classes to providers

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

    'api' => [
        'driver' => 'passport',
        'provider' => 'basic_users', // default
    ],        
],

...

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

Clean the cache via CLI

php artisan config:cache

Step 2: Create middleware

php artisan make:middleware AdminUserProvider

Open the newly created middleware in app/Http/Middleware and update the hand method like below

public function handle($request, Closure $next)
{
    config(['auth.guards.api.provider' => 'admin_users']);
    return $next($request);
}

Step 3: Register your middleware

Add the newly created middleware to $routeMiddleware

protected $routeMiddleware = [
    ...
    'auth.admin' => \App\Http\Middleware\AdminUserProvider::class,
];

and make sure it's at the top of $middlewarePriority

protected $middlewarePriority = [
    \App\Http\Middleware\AdminUserProvider::class,
    ...
];

Step 4: Add middleware to route

Route::group(['middleware' => ['auth.admin','auth:api']], function() {

Step 5: LoginControllers (AdminUserController & BasicUserController)

public function login()
{
    $validatedData = request()->validate([
        'email' => 'required',
        'password' => 'required|min:6'
    ]);
    // get user object
    $user = AdminUser::where('email', request()->email)->first();
    // do the passwords match?
    if (!Hash::check(request()->password, $user->password)) {
        // no they don't
        return response()->json(['error' => 'Unauthorized'], 401);
    }
    // log the user in (needed for future requests)
    Auth::login($user);
    // get new token
    $tokenResult = $user->createToken($this->tokenName);
    // return token in json response
    return response()->json(['success' => ['token' => $tokenResult->accessToken]], 200);
}

In summary:

The login controllers use Eloquent models to get the user object and then log the user in through Auth::login($user)

Then for future requests that need authentication, the new middleware will change the api auth guard provider to the correct class.
