apiinterfacemagento2overrides

I need to override below two core file of vendor folder :

vendor/magento/module-quote/Api/Data/ShippingMethodInterface.php

vendor/magento/module-quote/Model/Cart/ShippingMethod.php

file to my code folder.

Best Answer

vendor/magento/module-quote/Api/Data/ShippingMethodInterface.php is already override magento quote model.

<preference for="Magento\Quote\Api\Data\ShippingMethodInterface" 
type="Magento\Quote\Model\Cart\ShippingMethod" />

So you should Override the class Magento\Quote\Model\Cart\ShippingMethod

Not ShippingMethodInterface.

Magento 2 Override – How to Override Core Interface and Model

Below solution worked for me.

As per MIKE suggested we can't directly override magento's core interfaces.

So than there's comes role of Extension Attributes.

etc/extension_attributes.xml

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Api/etc/extension_attributes.xsd">
 <extension_attributes for="Magento\Checkout\Api\Data\ShippingInformationInterface">
    <attribute code="custom_shipping_charge" type="string"/>
</extension_attributes>

<extension_attributes for="Magento\Customer\Api\Data\GroupInterface">
    <attribute code="custom_shipping_amount" type="string"/>
</extension_attributes>

</config>

Execute : php bin/magento setup:di:compile

After that your get and set method will generated under below path.

magento_root/generated/code/Magento/Customer/Api/Data/GroupExtensionInterface.php

Now you can use those methods.

$groups->getCustomShippingAmount();
$groups->setCustomShippingAmount();

Hope this will help you.
