Php 方法\Http\RedirectResponse:：getData不存在。登录后页面

我的登录验证有问题。我以前已经使用过Laravel的身份验证（通过使用

make:auth

），然后我决定使用自己的身份验证进行更改，并收到以下错误消息：

这是我的路线配置：

Route::get('/home', 'HomeController@index')->name('home');
Route::post('login', 'authController@logIn');
Route::get('logout', 'authController@weblogOut');

Route::get('login', 'authController@showLogInPage');
Route::post('check_login', 'authController@checkLoginForWeb');
Route::get('web_logout', 'authController@webLogOut');

这是我的登录表：

<form method="POST" action="{{ url('check_login') }}" aria-label="{{ __('Login') }}">
    @csrf
    <div class="form-group has-feedback">
      <input id="email" type="email" class="form-control{{ $errors->has('email') ? ' is-invalid' : '' }}"
             name="email" placeholder="Email" value="{{ old('email') }}" required autofocus>
      <span class="glyphicon glyphicon-envelope form-control-feedback"></span>
    </div>
    <div class="form-group has-feedback">
      <input id="password" type="password"
             class="form-control{{ $errors->has('password') ? ' is-invalid' : '' }}" name="password"
             placeholder="Password" required>
      <span class="glyphicon glyphicon-lock form-control-feedback"></span>
    </div>
    <div class="row">
      <div class="col-xs-8">
        <div class="checkbox icheck">
          <label class="form-check-label" for="remember">
            <input type="checkbox"> Remember Me
          </label>
        </div>
      </div>
      <!-- /.col -->
      <div class="col-xs-4">
        <button type="submit" class="btn btn-primary btn-block btn-flat">Sign In</button>
      </div>
      <!-- /.col -->
    </div>
  </form>

如果我没有包含所需的函数，请在注释部分告诉我。

这对我来说很有用：

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Input;
use App\User;
class UserController extends Controller {
    /**
     * Send back all users as JSON
     *
     * @return Response
     */
    public function index() {
        return response()->json(User::get(), 200);
    }
    /**
     * Store a newly created resource in storage.
     *
     * @return Response
     */
    public function store() {
        User::create(array(
            'user_id' => Input::get('user_id'),
            'post_id' => Input::get('post_id'),
            'text' => Input::get('text')
        ));
        return response()->json(array('success' => true), 200);
    }
    /**
     * Return the specified resource using JSON
     *
     * @param  int  $id
     * @return Response
     */
    public function show($id) {
        return response()->json(User::find($id));
    }
    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return Response
     */
    public function destroy($id) {
        Comment::destroy($id);
        return response()->json(array('success' => true), 200);
    }
}

只需使用

return response（）->json（数组（'success'=>'login Successful'），200）

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Input;
use App\User;
class UserController extends Controller {
    /**
     * Send back all users as JSON
     *
     * @return Response
     */
    public function index() {
        return response()->json(User::get(), 200);
    }
    /**
     * Store a newly created resource in storage.
     *
     * @return Response
     */
    public function store() {
        User::create(array(
            'user_id' => Input::get('user_id'),
            'post_id' => Input::get('post_id'),
            'text' => Input::get('text')
        ));
        return response()->json(array('success' => true), 200);
    }
    /**
     * Return the specified resource using JSON
     *
     * @param  int  $id
     * @return Response
     */
    public function show($id) {
        return response()->json(User::find($id));
    }
    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return Response
     */
    public function destroy($id) {
        Comment::destroy($id);
        return response()->json(array('success' => true), 200);
    }
}
