我正在开发一个Shopware 6插件，并在其产品详细信息页面上设置产品的运费CustomsProductDetailRoute。
我制定了一个运送到法国的规则。现在，当我：

• 用我的ID登录Shopware商店。
• 将法国地址设置为默认送货地址。
• 我看到了到法国的运费。

这不应该发生。我想显示到销售渠道默认国家/地区的运费。

/**
     * @Entity("product")
     * @Route("/store-api/product/{productId}", name="store-api.detail", methods={"POST"})
     */
    public function load(string $productId, Request $request, SalesChannelContext $context, Criteria $criteria): ProductDetailRouteResponse
    {
        // We must call this function when using the decorator approach
        $productDetailResponse = $this->decorated->load($productId, $request, $context, $criteria);
        
        //Get the current Cart(CartService) and add a product as a new line item
        $cart = $this->cartService->getCart(self::DUMMY_TOKEN, $context);
//       dd($cart->getShippingCosts());
        
//        To avoid the cart from being persisted after the calculation, you can set a dummy value as token for the cart 
        $cart->setToken(self::DUMMY_TOKEN);
//        Get the default shipping address for the current sales channel from the SalesChannelContext
//        dd($context->getSalesChannel()->getCountryId());
        
//        Create a new lineItem of product
        $productLineItem = new LineItem($productId, LineItem::PRODUCT_LINE_ITEM_TYPE, $productId);
        
        $productLineItem->setGood(true);
        $productLineItem->setStackable(true);
        $productLineItem->setRemovable(true);
        
        $cart->add($productLineItem);
        
//        Setting the isRecalculation flag of CartBehavior should prevent cart to be persisted 
        $behaviorContext = new CartBehavior([], true, true);
        
        $cartLoaded = $this->cartRuleLoader->loadByCart($context, $cart, $behaviorContext)->getCart();
        
//        Access calculated shipping cost from the cart for the specific product
        $expectedShippingCosts = $cartLoaded->getShippingCosts();

//        Set the expected shipping cost to the extension of the $productDetailResponse's object variable
//        dd($productDetailResponse->getResult());
        $productDetailResponse->getProduct()->addExtension(
                'expectedShippingCosts', $expectedShippingCosts);
        
        return $productDetailResponse; 
    }

我正在尝试使用$context->getSalesChannel()->getCountryId()从SalesMailContext获取当前销售渠道的默认送货地址。我不确定如何将其与购物车关联。由于$cart没有设置送货国家/地区的方法。我如何修改代码以始终显示为销售渠道的默认国家/地区计算的运费？我希望它忽略用户的默认送货地址国家/地区。
问候，Lodhi
