Php Laravel-ErrorException:未定义变量：Laravel Passport登录中的请求

我在Laravel-8项目Passport API认证中有以下代码：

验证请求规则：

class LoginRequest extends FormRequest
{
  public function rules()
  {
      return [
      'email' => 'required_without:mobile_number|string',
      'mobile_number' => 'required_without:email|string',
      'password' => 'required|string',
      'remember_me' => 'boolean'
      ];
  }
}

控制器：

public function login(LoginRequest $request)
{
    DB::beginTransaction();
try {
    $confirmUser = User::where('active', 1)->where(function ($query) {
        $query->where('email', $request->email)->orWhere('mobile_number', $request->mobile_number);
    })->whereNull('deleted_at')->first();
    if(!$confirmUser){
        return $this->error('User doesn\'t exist', 404);
    }
    $authenticated = false;
    $remember = $request->remember_me ? true : false;
    if (Auth::attempt(['email' => $request->email, 'password' => $request->password], $remember)) {
        $authenticated = true;
    } elseif (Auth::attempt(['mobile_phone' => $request->mobile_number, 'password' => $request->password], $remember)) {
        $authenticated = true;
    }
    if ($authenticated == true) {
        $user = Auth::user();
        $tokenResult = $user->createToken('iDriver');
        $token = $tokenResult->token;
        if ($request->remember_me)
            $token->expires_at = Carbon::now()->addWeeks(1);
        $token->save();
        // User Log
        if(Auth::loginUsingId($user->id))
        {
            $user->update([
                 'last_login_at' => now(),
            ]);
        }
        DB::commit();
        return $this->success('You have successfully Logged In.', [
            'user'         => $user,
            'access_token' => $token,
            'expires_at' => Carbon::parse(
                $tokenResult->token->expires_at
            )->toDateTimeString()
        ]);
    } else {
        return $this->error('Invalid User Credential', 401);
    }
    } catch(\Exception $e) {
        DB::rollback();
        Log::error($e);
        return $this->error($e->getMessage(), $e->getCode());
    }
}

用户可以使用电子邮件或手机号码登录

当我测试它时，我得到了这个错误：

2021-05-19 14:39:07]local.ERROR:ErrorException:未定义变量：C:\xampp\htdocs\myapp\app\Controllers\AuthController.php:92中的请求

这是第92行：

$query->where（'email'，$request->email）->或where（'mobile\u number'，$request->mobile\u number）

我如何解决这个问题

谢谢

使用

request（）

或

->where（函数（$query）使用（$request）
