将Magento 1.9的运输扩展迁移到Magento 2.2

问题描述：

我正尝试将一个自定义magento 1.9扩展迁移到magento 2.2。我做了很多搜索，找不到我正在尝试迁移的用例的相关信息。我最初遵循this tutorial的1.9扩展。我知道有一种工具可以帮助端口扩展，但我正在尝试手动执行此操作，因为我无法让该工具为我工作。将Magento 1.9的运输扩展迁移到Magento 2.2

每次更新购物车以计算自定义运费时，都会运行自定义送货延期。我们的目标是在magento 2.2中重新创建此扩展，以便每次购物车打开或更新时，它都会运行并计算运输成本，然后通过结帐流程进行传播。

下面是对magento 1.9扩展的概述。有关如何将其转换为magento 2.2的建议？

答

您可以在checkout_cart_add_product_complete事件创建一个事件观察者执行逻辑更新运费。

namespace MyCompany\MyModule\Observer; 

use Magento\Framework\Event\ObserverInterface; 

class MyObserver implements ObserverInterface 
{ 
    public function __construct() 
    { 
    //Observer initialization code... 
    //You can use dependency injection to get any class this observer may need. 
    } 

    public function execute(\Magento\Framework\Event\Observer $observer) 
    { 
    //Observer execution code... 
    } 
}

订阅事件events.xml：

<?xml version="1.0"?> 
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd"> 
    <event name="my_module_event_before"> 
     <observer name="myObserverName" instance="MyCompany\MyModule\Observer\MyObserver" /> 
    </event> 
    <event name="my_module_event_after"> 
     <observer name="myObserverName" instance="MyCompany\MyModule\Observer\AnotherObserver" /> 
    </event> 
</config>
