Cart API: cart.data.data.cart_amount没有正确计算.我认为

Question

1. 增加了一个产品到购物车使用API价格是29美元
2. GET /v3/carts/cartId saw cart_amount是正确的
3. 将产品价格改为100美元
4. GET /v3/carts/cartId认为cart_amount错了--它没有看到产品价格发生了变化。

我是不是做错什么了。你需要更多的信息来帮助我吗？

bc.add_to_cart = (data,next) => {
    let payload = {
        line_items: data.line_items,
        option_selections: data.option_selections,
        gift_certificatesL: null
    }
    return bc_v3.post(`/carts/${data.cartId}/items`, payload).then(data => {
        return data; // data only show initial product cost
    }).catch(next);
};

编辑

下面我张贴的GET carts/id u的结果，将看到lineItem (id: 125)显示原始价格，29.95。在得到购物车后，我立即向GET /catalog/products/125提出了一个请求--该请求显示了更新的价格。

GET: carts/${cartId}

Answer 1

更新控制面板中项目的价格或使用API不会更改现有购物车中的价格。如果您创建了一个新的购物车，那么价格将反映所做的更改。

原来的购物车line_item是25美元，税金也包括在内，cart_amount是29.12美元

        "base_amount": 25,
        "discount_amount": 0,
        "cart_amount": 29.12,
        "coupons": [],
        "line_items": {
            "physical_items": [
                {
                    "id": "1e08875e-bf6f-4f1f-b8ba-b2e3cee10394",

        "updated_time": "2018-08-24T14:41:17+00:00"
    },
    "meta": {}
}

更新line_item价格/{store_hash}/v3/carts/{cartId}/items/{itemId}

{
    "line_item":
        {
            "list_price": 30,
            "quantity": 1,
            "product_id": 192
        }
}

响应-- base_amount现在为30，cart_amount也更新为34.96。这只会改变购物车的价格，而不会改变产品的价格。
