Laravel Auth：这些凭证与我们的记录不符

我是Laravel的新手 . 我很享受这个框架的每一点 . 我最近遇到了一些身份验证/登录问题 .

用户注册工作正常，但当我尝试使用注册期间创建的相同凭据登录时，应用程序会抛出此错误：

这些凭据与我们的记录不符

我还查看了数据库中的users表，并捕获了注册表单中的所有字段 . 我只是想知道为什么应用程序无法从数据库中检索这些 .

请参阅下面的LoginController代码：

namespace App\Http\Controllers\Auth;

use App\Models\User;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Firebase\JWT\JWT;

class LoginController extends Controller
{
/*
|--------------------------------------------------------------------------
| Login Controller
|--------------------------------------------------------------------------
|
| This controller handles authenticating users for the application and
| redirecting them to your home screen. The controller uses a trait
| to conveniently provide its functionality to your applications.
|
*/

use AuthenticatesUsers;

/**
 * Where to redirect users after login.
 *
 * @var string
 */
protected $redirectTo = '/dashboard';

// Get your service account's email address and private key from the JSON 
key file
protected $service_account_email = "abc-123@a-b-c-
123.iam.gserviceaccount.com";

protected $private_key = "-----BEGIN PRIVATE KEY-----...";

/**
 * Create a new controller instance.
 *
 * @return void
 */
public function __construct()
{
    $this->middleware('guest')->except('logout');

    $this->service_account_email = config('services.firebase.client_email');
    $this->private_key = config('services.firebase.private_key');
}

    /**
 * Get the needed authorization credentials from the request.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return array
 */
protected function credentials(Request $request)
{
    $data = $request->only($this->username(), 'password');
    $data['email_confirmed'] = 1;
    return $data;
}

protected function authenticated(Request $request, $user)
{

    $jwt = $this->create_custom_token($user,false);

    session(['jwt' => $jwt]);

    return redirect()->intended($this->redirectPath());
}

function create_custom_token(User $user, $is_premium_account) {

    $now_seconds = time();
    $payload = array(
        "iss" => $this->service_account_email,
        "sub" => $this->service_account_email,
        "aud" => "https://identitytoolkit.googleapis.com/google.identity.identitytoolkit.v1.IdentityToolkit",
        "iat" => $now_seconds,
        "exp" => $now_seconds+(60*60),  // Maximum expiration time is one hour
        "uid" => $user->ref_code,
        "email" => $user->email,
        "name" => $user->name,
        "phone_number" => $user->phone_number,
        "claims" => array(
            "premium_account" => $is_premium_account
        )
    );
    return JWT::encode($payload, $this->private_key, "RS256");
    }

    }

我怎样才能解决这个问题？
