Laravel 5.1 调用未定义的方法 Illuminate\Support\Facades\Request::cookie()

Question

我试图在 Laravel 5.1 中的控制器中加载 cookie 的值，但出现此错误：

FatalErrorException in SurveyController.php line 21: Call to undefined method Illuminate\Support\Facades\Request::cookie()

这是我的代码：

<?php

namespace App\Http\Controllers;
use Response;
use Request;
use Illuminate\Routing\Controller;
use Cookie;
use Log;

class SurveyController extends Controller {

    /**
     * Index method. Decide to resume a survey or start a new one.
     */
    public function index(Request $request) {

        dd($request->cookie('survey_id'));
    }
}

据我所知 the documents，这似乎是加载 cookie 值的正确方法。我做错了什么？

Answer 1

所以而不是

use Request;

尝试

use Illuminate\Http\Request;

Answer 2

而不是使用

use Request;

它使用 Illuminate\Support\Facades\Request

使用

use Illuminate\Http\Request;

Laravel 5.1 调用未定义的方法 Illuminate\Support\Facades\Request::cookie()

Laravel 5.1 Call to undefined method Illuminate\Support\Facades\Request::cookie()
