我正在使用Laravel 5.3 並且我試圖在constructor 方法中獲取經過身份驗證用戶的id ，以便我可以依指定公司過濾用戶，如下所示：
namespace AppHttpControllers;
use IlluminateFoundationBusDispatchesJobs;
use IlluminateRoutingController as BaseController;
use IlluminateFoundationValidationValidatesRequests;
use IlluminateFoundationAuthAccessAuthorizesRequests;
use IlluminateSupportFacadesView;
use AppModelsUser;
use AppModelsCompany;
use IlluminateSupportFacadesAuth;
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);
}
}
但是這不會回傳使用者 id。我什至嘗試過 Auth::check() 但它不起作用。
如果我將 Auth::check() 移出 __construct() 方法，則其工作原理如下：
<?php
namespace AppHttpControllers;
use IlluminateHttpRequest;
class HomeController extends Controller
{
/**
* Create a new controller instance.
*
* @return void
*/
public function __construct()
{
parent::__construct();
$this->middleware('auth');
}
/**
* Show the application dashboard.
*
* @return IlluminateHttpResponse
*/
public function index()
{
dd(Auth::check());
return view('home');
}
}
但是，如果我也將其放入 HomeController 的建構方法中，則此失敗！
有什麼想法為什麼會失敗嗎？
自 5.3
Auth::check起，它將無法在控制器的建構子中運作，這是未記錄的變更之一。因此，您需要將其移至中間件或檢查控制器方法，或將項目移至 5.2.x。文件
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); }); } }
