Magento 2矩阵费率结帐问题（找不到使用这种方法的运营商：matrixrate_5334）

我注意到，由于在计算运费时，结帐会话报价$this->getShippingMethod()设置不正确/为空，因此发生了此错误。

magento/codepool/vendor/magento/module-quote/Model/Quote/Address.php
public function requestShippingRates(AbstractItem $item = null)
Line 1080: if ($this->getShippingMethod() == $rate->getCode()) {

错误：

{"message":"Carrier with such method not found: %1,%2","parameters":["matrixrate","matrixrate_2"]}

解决方案：

我可以通过覆盖\WebShopApps\MatrixRate\Model\Carrier\Matrixrate collectRates()方法来解决该问题，并在结帐报价送货地址中设置送货方式。

// set quote shipping method
$shippingMethod = $method->getCarrier().'_'.$method->getMethod();
$this->checkoutSession->getQuote()->getShippingAddress()->setShippingMethod($shippingMethod);

========================================== >

Vendor/MatrixRate/etc/di.xml

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="WebShopApps\MatrixRate\Model\Carrier\Matrixrate" type="Vendor\MatrixRate\Model\Carrier\Matrixrate"/>
</config>

覆盖Vendor\MatrixRate\Model\Carrier\Matrixrate.php

将\Magento\Checkout\Model\Session $checkoutSession注入到__construct

public function collectRates(RateRequest $request)
    {
        if (!$this->getConfigFlag('active')) {
            return false;
