如何在 Laravel 和 Dontrine 中更改 JWT 身份验证的默认表/模型（用户）？

Question

I am working on a project that was built on Laravel 5.4.24 and integrated with Symfony component and Doctrine . I need to authenticate staffs on request from site_staffs table (SiteStaff model) and return the token. site_staffs table has these columns: (id, site_id , code, number,..) . Some columns have different names in the SiteStaff entity (id, site , code,..) . There is another table for users and I have no issue to authenticate users and return the token. (In my case, I don't need to authenticate users and I just did that for testing). The issue is when I try to change the default settings of JWT to authenticate staffs from site_staffs table as below, I get an error message (see down the page):

config/jwt.php:

//'user' => 'App\User',
'user' => 'App\Entities\SiteStaff',

config/auth.php:

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

    'api_token' => [
       'driver' => 'api_token',
       'provider' => 'users',
     ],

    //'api' => [
        //'driver' => 'jwt',
        //'provider' => 'users',
    //],        
   ],

    'providers' => [
        'users' => [
            'driver' => 'doctrine',
             //'model' => App\Entities\User::class,
            'model' => App\Entities\SiteStaff::class,            
        ],

pi/SiteStaffController:

I am passing the credentials to JWT as follow:

$credentials = 
    [
        'site'     =>  $bpId,
        'code'  =>  $lanyard_code
    ];   

if(! $token = JWTAuth::attempt($credentials)){
      return response()->json(['error' => ['messages' => 
      ['Invalid credentials'] ]
   ], IlluminateResponse::HTTP_UNAUTHORIZED);
 }else{
    dd($token);
 }   

Here is the error I get:

Type error: Argument 1 passed to 

Tymon\JWTAuth\Providers\User\EloquentUserAdapter::__construct() must be an 
instance of Illuminate\Database\Eloquent\Model, instance of 
App\Entities\SiteStaff given, called in /vagrant/vendor/tymon/jwt-
auth/src/Providers/JWTAuthServiceProvider.php on line 126

I tried many different ways and solutions but non of them worked for me. I appreciate if you could let me know what is wrong and what am I missing? Your help is highly appreciated.

Answer 1

As per the requirement to change users table name for jwt auth in laravel need to follow two-step changes which I have tried.

I have changed successfully login/authentication table from users to a customer with following steps.

step-1: change below details for providers

config/auth.php

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

step-2: change in jwt file

config/jwt.php

// here to give a model path for authentication
'user' => 'App\Models\Customer',

Answer 2

In my scenario I have two guards, web and api:

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

    'api' => [
        'driver' => 'jwt',
        'provider' => 'managers',
        'hash' => false,
    ]
],

So, I follow these steps described in Tymon's Jwt Library docs:

"If the newly created 'api' guard is not set as a default guard or you have defined multiple guards to handle authentication, you should specify the guard when calling auth()."

$token = auth('api')->attempt($credentials);

In my custom api auth controller I had implemented login method as below and it works:

public function login(Request $request)
{
    $this->validateLogin($request);
    
    $credentials = $this->credentials($request);
    
    $token = auth('api')->attempt($credentials);

    return $token
        ? ['token' => $token]
        : response()->json(['error' => \Lang::get('auth.failed')], 401);
}
