Laravel 5.6 策略在远程服务器上运行不正常

Question

我创建了一个名为 LetterPolicy 的策略，这是代码

    namespace App\Policies;

    use App\Letter;
    use App\User;
    use Illuminate\Auth\Access\HandlesAuthorization;

    class LetterPolicy
    {
        use HandlesAuthorization;

        /**
         * Create a new policy instance.
         *
         * @return void
         */

        public function __construct()
        {
            //
        }

        public function update(User $user, Letter $letter)
        {
            return($user->id === $letter->user_id || $user->role_id===1 ) ;
        }
    }

这是authserviceprovider

namespace App\Providers;

use App\Letter;
use App\Policies\LetterPolicy;
use App\Policies\UserPolicy;
use App\User;
use Illuminate\Support\Facades\Gate;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;

class AuthServiceProvider extends ServiceProvider
{
    /**
     * The policy mappings for the application.
     *
     * @var array
     */
    protected $policies = [
        'App\Model' => 'App\Policies\ModelPolicy',
        User::class => UserPolicy::class,
        Letter::class => LetterPolicy::class,
    ];

    /**
     * Register any authentication / authorization services.
     *
     * @return void
     */
    public function boot()
    {
        $this->registerPolicies();
        //
    }
}

在下面的代码中我检查了用户

class LetterController extends Controller
{
protected $user;
public function __construct()
{
    $this->middleware(function ($request, $next){
       $this->user = Auth::user();
        return $next($request);
    });

}
public function edit(Letter $letter)
{
    if($this->user->can('update', $letter)){           
       //edit
    }
    else
        abort('403', 'Access Denied');
}

该代码在本地主机上运行良好，但在远程服务器上它报告 access denied 错误。我在服务器上部署站点后创建了此策略，因此我使用代码

创建了一个路由 /clear-cache

    Route::get('/clear-cache', function() {
        $exitCode = \Illuminate\Support\Facades\Artisan::call('cache:clear');
    });

创建策略后清除缓存。但是还是报403错误。有什么问题？

Answer 1

我在控制器中尝试 dd($this->user->id === $letter->user_id || $this->user->role_id===1 );，它返回 false。我试了 dd($this->user->id == $letter->user_id || $this->user->role_id==1 );，结果是 true。现在可以了，但我不知道为什么！！！

Answer 2

Fjarlaegur 的回答是关键。我遇到了同样的问题：在 localhost 中没有问题，但在生产服务器中，不知何故每次授权都失败了，这是因为比较运算符。从 === 更改为 ==，一切正常。
