magento - 自定义模块在 Magento2 中不起作用

Question

我一直在尝试在 Magento2 中设置一个基本模块，尽管做了所有理想的更改，它仍然会抛出 404。下面是与模块相关的代码。我的供应商名称是Chirag，模块名称是HelloWorld。

/var/www/html/magento2/app/code/Chirag/HelloWorld/etc/module.xml

        </route>
    </router>
</config>

/var/www/html/magento2/app/code/Chirag/HelloWorld/Controller/Index/Index.php

<?php
/**

namespace Chirag\HelloWorld\Controller\Index;

class Index extends \Magento\Framework\App\Action\Action

    /**

     * @return void
     */
    public function execute()
    {
        protected $resultPageFactory;
        public function __construct(
            \Magento\Framework\App\Action\Context $context,
            \Magento\Framework\View\Result\PageFactory $resultPageFactory
        )
        {
            parent::__construct($context);
            $this->resultPageFactory = $resultPageFactory;
        }

        public function execute()
        {
            return $this->resultPageFactory->create();
        }
    }
}

/var/www/html/magento2/app/code/Chirag/HelloWorld/Block/HelloWorld.php

<?php
namespace Chirag\HelloWorld\Block;

class HelloWorld extends \Magento\Framework\View\Element\Template
{

}

/var/www/html/magento2/app/code/Chirag/HelloWorld/view/frontend/layout/helloworld_index_index.xml

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd">
    <body>
        <referenceContainer name="content">
            <block class="Chirag\HelloWorld\Block\HelloWorld" name="helloworld" template="helloworld.phtml" />
        </referenceContainer>
    </body>
</page>

<h1> test hello to Magento 2 !! </h1>

首先尝试重命名route.xml为routes.xml，看看是否能解决问题。

接下来尝试更改控制器中的代码，尝试更改公司/模块名称：

<?php

namespace YourCompany\ModuleName\Controller\Index;

class Index extends \Magento\Framework\App\Action\Action
{
    protected $resultPageFactory;

    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\View\Result\PageFactory $resultPageFactory
    ) {
        parent::__construct($context);
        $this->resultPageFactory = $resultPageFactory;
    }

    public function execute()
    {
        return $this->resultPageFactory->create();
    }
}

您helloworld_index_index.xml也可以尝试将模板装饰更改为：

template="YourCompany_ModuleName::templatename.phtml"

最后，您可以尝试将module.xml setup_version声明更改为：

setup_version="2.0.0"

我希望这有帮助！

以下更改为我带来了正确的答案：

索引控制器 - magento2/app/code/Chirag/HelloWorld/Controller/Index/Index.php

<?php
/**
 *
 * Copyright © 2015 Magento. All rights reserved.
 * See COPYING.txt for license details.
 */
namespace Chirag\HelloWorld\Controller\Index;

class Index extends \Magento\Framework\App\Action\Action
{
    /**
     * Show Contact Us page
     *
     * @return void
     */
    public function execute()
    {
        $this->_view->loadLayout();
        $this->_view->getLayout()->getBlock('helloworld');
        $this->_view->renderLayout();
    }
}

块 - magento2/app/code/Chirag/HelloWorld/Block/Question.php

<?php
/**
 * Copyright © 2015 Magento. All rights reserved.
 * See COPYING.txt for license details.
 */
namespace Chirag\HelloWorld\Block;

use Magento\Framework\View\Element\Template;

/**
 * Main contact form block
 */
class Question extends Template
{
    /**
     * @param Template\Context $context
     * @param array $data
     */
    public function __construct(Template\Context $context, array $data = [])
    {
        parent::__construct($context, $data);
        $this->_isScopePrivate = true;
    }
}

布局文件 - magento2/app/code/Chirag/HelloWorld/view/frontend/layout/helloworld_index_index.xml

<?xml version="1.0"?>
<!--
/**
 * Copyright © 2015 Magento. All rights reserved.
 * See COPYING.txt for license details.
 */
-->
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd">
    <body>
        <referenceContainer name="content">
            <block class="Chirag\HelloWorld\Block\Question" name="helloworld" template="Chirag_HelloWorld::helloworld.phtml">
            </block>
        </referenceContainer>
    </body>
</page>

查看模板 - magento2/app/code/Chirag/HelloWorld/view/frontend/templates/helloworld.phtml

<?php echo 'helloworld view'; ?>
<h1> Hello World </h1>

首先，重命名route.xml为routes.xml

应用程序/代码/Chirag/HelloWorld/etc/frontend/routes.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
    <router id="standard">
        <route id="helloworld" frontName="helloworld">
            <module name="Chirag_HelloWorld" />
        </route>
    </router>
</config>

索引控制器 - app/code/Chirag/HelloWorld/Controller/Index/Index.php

您不能__construct在方法内部使用execute，这两者应该分开。

<?php
/**
 *
 * Copyright © 2015 Magento. All rights reserved.
 * See COPYING.txt for license details.
 */

namespace Chirag\HelloWorld\Controller\Index;

use Magento\Framework\App\Action\Action;

class Index extends Action
{
    /**
     * @var \Magento\Framework\View\Result\PageFactory
     */
    protected $resultPageFactory;

    /**
     * @param \Magento\Framework\App\Action\Context $context
     * @param \Magento\Framework\View\Result\PageFactory $resultPageFactory
     */
    public function __construct(
        \Magento\Framework\App\Action\Context      $context,
        \Magento\Framework\View\Result\PageFactory $resultPageFactory
    )
    {
        parent::__construct($context);
        $this->resultPageFactory = $resultPageFactory;
    }

    /**
     * @return mixed
     */
    public function execute()
    {
        return $this->resultPageFactory->create();
    }
}

在布局 xml 中调用模板时，应使用以下格式。

例如：Chirag_HelloWorld::helloworld.phtml

app/code/Chirag/HelloWorld/view/frontend/layout/helloworld_index_index.xml

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd">
    <body>
        <referenceContainer name="content">
            <block class="Chirag\HelloWorld\Block\HelloWorld" name="helloworld" template="Chirag_HelloWorld::helloworld.phtml" />
        </referenceContainer>
    </body>
</page>

应用程序/代码/Chirag/HelloWorld/Block/HelloWorld.php

<?php
namespace Chirag\HelloWorld\Block;

class HelloWorld extends \Magento\Framework\View\Element\Template
{
    public function getHelloWorldText()
    {
        return __('Hello World');
    }
}

应用程序/代码/Chirag/HelloWorld/view/frontend/templates/helloworld.phtml

<?= /* @noEscape */ $block->getHelloWorldText() ?>

完成后运行以下命令以应用更改。

bin/magento setup:upgrade
bin/magento setup:static-content:deploy -f
bin/magento c:f

-f如果您处于开发人员模式，请用作参数。

用于bin/magento deploy:mode:show检查模式。

编码快乐！！
