Laravel 5.6从资源中获取中间件中请求的id

Question

我的资源路线：

Route::resource('imagerequests', 'ImageRequestController');

在浏览器中看起来是这样的：

/imagerequests/19/edit

在我的控制器构造器中，我这样做是因为只有当用户进入编辑页面时，我才需要中间件：

$this->middleware('edit')->only('edit');

我的编辑中间件：

public function handle($request, Closure $next)
{
dd($request->id);
}

这将返回null

我也试过了，还返回了null

public function handle($request, Closure $next)
{
dd($request->imagerequests);
}

当我进入时，我如何访问id

dd($request);结果

我不能100%确定这对中间件的作用与对控制器的作用相同，但在控制器中，你会键入来自URL的模型，如下所示：

public function handle($request, Imagerequest $imagerequest, Closure $next)
{
$imagerequest->id
}

当然，您还需要在开始时添加：

use AppImagerequest;
