如何在laravel 5中将参数从路由器传递到中间件？

Question

我最近遇到了一个问题，当时我试图将参数从路由器传递到我的中间件，以检查经过身份验证的用户是否具有访问该路由的权限。 如何将路由中的参数传递给中间件？

Answer 1

我试着这样做，对我来说效果很好： 在我的路线文件中：

Route::group(['prefix' => 'agenda', 'middleware' => 'auth', 'permissions' => 'user.create|user.delete'], function() {
    //my routes here...
});

并在中间件内部：

class AuthMiddleware {
    private $r;
    private $guard;
    public function __construct(Router $r, Guard $g)
    {
        $this->r = $r;
        $this->guard = $g;
    }

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        $route = $this->r->getCurrentRoute();
        $action = $route->getAction(); //$action['permissions'] is the string received from the routes file.
    }
