php - Laravel - 不允许用户访问其他用户数据

Question

在 Laravel 中，我们如何限制用户访问其他用户的数据？

我需要在每个路由函数中写下代码吗？还是 laravel 提供了以中心为中心的方法？

Answer 1

虽然我不知道您的用例，但假设您想保护您的用户不看到其他用户的个人资料。现在，如果您的显示用户路线类似于

/users/{id}

然后创建一个中间件让我们说 myAuth

class MyAuth
{
  public function handle($request, Closure $next)
  {
    if(!auth()->check && !auth()->user()->id == request()->get('id'))
    {
      dd("you are not allowed to see this");
    }

    return $next($request);
  }
}

并将其包含在您的 Http/kernel.php

protected $routeMiddleware = [
    'auth' => \App\Http\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'admin' => \App\Http\Middleware\Admin::class,
    //Your new middleware
    'myAuth' => \App\Http\Middleware\MyAuth::class,
];

并在此中间件中包含您的路由

Route::group(['middleware' => 'myAuth'], function () {    
    Route::get('user/{id}', function () {
        //Only user with id 1 can see profile of user with id 1
    });
});
