必须定义参数“id”

Question

当我尝试访问我的子页面时，此错误会弹出

The parameter "id" must be defined.

//        $paginator->setItemCountPerPage(10);//        $this->view->paginator  = $paginator;    }    public function blogarticleAction(){        $this->view->blogarticle = \Pimcore\Model\DataObject\Blogpost::getById($this->getParameter("id"));    }}

我曾经做过的代码

default.html.php

<div class="post-preview">
    <a href="<?= $this->path('blogpost', [
                    'id' => $blogpost-> getId(),
                    'title' => $blogpost -> getTitle(),
            ]); ?>">

defaultcontroller.php

 public function blogarticleAction($id){
     $this->view->blogarticle = \Pimcore\Model\DataObject\Blogpost::getById($this->getParam("id"));
}

RegEx设置：

当然，我在与blogarticle.html.php

相同的文件夹中创建了default.html.php

从行动中使用$id，而不是从容器

public function blogarticleAction($id){
     $this->view->blogarticle = \Pimcore\Model\DataObject\Blogpost::getById($id);
}

$this->getParam("id")将在容器中查找名为id的参数，这不是您想要的
