1. 使用API将产品添加到购物车的价格为29美元
2. GET /v3/carts/cartId 锯 cart_amount
3. 将产品价格更改为100美元
4. 获取/v3/carts/cartId 购物车数量 错了,它没有看到产品价格有变化。

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);
};

GET carts/id 29.95 GET /catalog/products/125 那个显示了最新价格。

GET: carts/${cartId}
