Laravel 5.3 auth check in constructor returning false
提问by 001221
I'm using Laravel 5.3and I'm trying to get the authenticateduser's idin the constructormethod so I can filter the user by assigned company as follows:
我正在使用Laravel 5.3并尝试在方法中获取经过身份验证的用户id，constructor以便我可以按指定的公司过滤用户，如下所示：
namespace App\Http\Controllers;
use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use Illuminate\Support\Facades\View;
use App\Models\User;
use App\Models\Company;
use Illuminate\Support\Facades\Auth;
class Controller extends BaseController
{
use AuthorizesRequests, DispatchesJobs, ValidatesRequests ;
public $user;
public $company;
public function __construct()
{
$companies = Company::pluck('name', 'id');
$companies->prepend('Please select');
view()->share('companies', $companies);
$this->user = User::with('profile')->where('id', \Auth::id())->first();
if(isset($this->user->company_id)){
$this->company = Company::find($this->user->company_id);
if (!isset($this->company)) {
$this->company = new Company();
}
view()->share('company', $this->company);
view()->share('user', $this->user);
}
}
However this doesn't return the user id. I've even tried Auth::check()and it doesn't work.
但是，这不会返回 user id。我什至尝试过Auth::check()，但它不起作用。
If I move the Auth::check()out of the __construct()method then this works as follows:
如果我将方法Auth::check()移出，__construct()则其工作原理如下：
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class HomeController extends Controller
{
/**
* Create a new controller instance.
*
* @return void
*/
public function __construct()
{
parent::__construct();
$this->middleware('auth');
}
/**
* Show the application dashboard.
*
* @return \Illuminate\Http\Response
*/
public function index()
{
dd(\Auth::check());
return view('home');
}
}
However this failsif I put this in the construct method in the HomeControllertoo!
但是，如果我将它放在构造方法中，这将失败HomeController！
Any ideas why this is failing?
任何想法为什么会失败？

you can't access the session or authenticated user in your controller's constructor because the middleware has not run yet.
As an alternative, you may define a Closure based middleware directly in your controller's constructor. Before using this feature, make sure that your application is running Laravel 5.3.4 or above:
您无法在控制器的构造函数中访问会话或经过身份验证的用户，因为中间件尚未运行。
作为替代方案，您可以直接在控制器的构造函数中定义基于闭包的中间件。在使用此功能之前，请确保您的应用程序运行的是 Laravel 5.3.4 或更高版本：
class ProjectController extends Controller
{
/**
* All of the current user's projects.
*/
protected $projects;
/**
* Create a new controller instance.
*
* @return void
*/
public function __construct()
{
$this->middleware(function ($request, $next) {
$this->projects = Auth::user()->projects;
return $next($request);
});
}
}

Since 5.3 Auth::checkwill not work in a controller's construtor, it's one of undocumented changes. So, you need to move it to middleware or do check in controller methods instead or move project to 5.2.x.
由于 5.3Auth::check在控制器的构造函数中不起作用，因此它是未记录的更改之一。因此，您需要将其移至中间件或改为检查控制器方法或将项目移至 5.2.x。

It fails because you call $this->middleware('auth');after parent::__construct();. It means that you auth middleware is not loaded properly.
它失败了，因为你$this->middleware('auth');在parent::__construct();. 这意味着您的身份验证中间件未正确加载。
