在magento2模块中获取产品列表

我正在尝试将所有产品列表提取到magento2应用程序中的模块中,但无法弄清楚如何。

我的区块代码:

class Crud extends \Magento\Framework\View\Element\Template
{
    protected $objectManager;
    public function __construct(Magento\Framework\View\Element\Template\Context $context,
        \Magento\Framework\View\Result\PageFactory $resultPageFactory,
        \Magento\Framework\ObjectManagerInterface $objectManager,
        \Magento\Framework\App\State $appState
    )
    {
        $this->objectManager = $objectManager;
      //  $appState->setAreaCode('frontend');
        parent::__construct($context);
    }

    function _prepareLayout(){}

    function getCrudName(){
        return "Products for holmes chat client";
    }

    function getProductList(){
     //   $objectMan= new \Magento\Framework\App\ObjectManager;
        $objectMan= $this->$objectManager;
        $repo = $objectMan->get('Magento\Catalog\Model\ProductRepository');
        $search_criteria = $objectMan->create(
            'Magento\Framework\Api\SearchCriteriaInterface'
        );
        $result = $repo->getList($search_criteria);
      //  $list = $repo->getList();
      $products = $result->getItems();
        return $products;
        // return 'some';
    }

    function getProducts(){
        $objectMan = new Holmes\ChatClient\Api\ProductFetcher;
    }
}

我的模板代码:

<h2>This is a crud html</h2>
<h3>

    <?php
        echo $block->getCrudName();
    ?>
</h3>
<ul>
    <?php
       echo $block->getProductList();
    ?>
</ul>

我的浏览器出现错误:

3 exception(s):
Exception #0 (Magento\Framework\Exception\LocalizedException): Invalid block type: Holmes\ChatClient\Block\Crud
Exception #1 (ReflectionException): Class Holmes\ChatClient\Block\Magento\Framework\View\Element\Template\Context does not exist
Exception #2 (ReflectionException): Class Holmes\ChatClient\Block\Magento\Framework\View\Element\Template\Context does not exist

我是magento的新手,如果删除构造函数并从代码中删除方法getProductList(),则块代码正常工作。我可以在magento Block中编写代码。

您忘记了声明功能的可见性。这可能会解决您的问题。如果没有,请包括您的布局xml文件,文件顶部的命名空间和控制器。

更改:

function getProducts(){public function getProducts() {

function _prepareLayout(){}protected function _prepareLayout(){}

function getCrudName(){public function getCrudName(){

function getProductList(){public function getProductList(){
