laravel - Laravel 5.5 类型错误：传递给 Illuminate\Auth\EloquentUserProvider::validateCredentials() 的参数 1 必须是实例

Question

在 Auth 下的 LoginController 中，我使用了以下代码：

namespace App\Http\Controllers\Auth;

use App\Model\Admin;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Input;
use Illuminate\Support\Facades\Validator;
use Illuminate\Support\Facades\Redirect;
use Hash;
use Auth;
use DB;
use App\Model\UserAdmin;

class LoginController extends Controller {
use AuthenticatesUsers;
public function __construct() {
        $this->middleware('guest')->except('logout');
    }

public function doLogin(Request $request) {
$userdata = array(
            'email' => Input::get('email'),
            'password' => Input::get('password'),
            'status' => '1',
        );
if (Auth::guard('admin')->attempt($userdata)) {
  return Redirect::intended('/administrator/dashboard')->with('successMessage', 'You have successfully logged in.');
}
}
}

而在app/Model下的UserAdmin(model)中如下：

namespace App\Model;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\DB;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Config;
class UserAdmin extends Authenticatable {
protected $table = 'adminusers';
    public $timestamps = false;
    protected $fillable = ['firstName', 'lastName', 'email', 'company', 'website'];

    public function __construct() {
        parent::__construct(); // Don't forget this, you'll never know what's being done in the constructor of the parent class you extended
    }

}

提交登录详细信息后，它向我显示错误：

类型错误：传递给 Illuminate\Auth\EloquentUserProvider::validateCredentials() 的参数 1 必须是 Illuminate\Contracts\Auth\Authenticatable 的实例，给出 App\Model\UserAdmin 的实例，在 /var/www/html/XXXXXX/ 中调用供应商/laravel/framework/src/Illuminate/Auth/SessionGuard.php 第 379 行

我想您需要将 implements \Illuminate\Contracts\Auth\Authenticatable 添加到您的 UserAdmin 模型类定义中。

    class UserAdmin extends Model implements 
    \Illuminate\Contracts\Auth\Authenticatable
