这篇博客介绍了Shopify平台中购物车的工作原理，强调了后端并不直接处理购物车，而是在浏览器端进行操作。通过AjaxAPI，特别是`cart.add.js`接口，可以实现对用户购物车的添加商品功能。示例展示了添加商品后的JSON响应数据，包括商品详情、价格、数量等信息。`cart.js`则用于获取购物车当前状态。博客内容对于理解和操作Shopify购物车系统至关重要。
Shopify后端对个人用户推车一无所知,它们只存在于浏览器领域.我的错误,后端知道购物车,但你不能通过REST API编辑它们.
Here’s the Cart endpoint if you’re interested in getting carts.
要操纵用户的购物车,您需要使用店面的Ajax API.具体来说,this call将向购物车添加产品：
http://store.myshopify.com/cart.add.js?quantity=2&id=30104012
返回看起来像这样的json：
{
"handle": "amelia",
"line_price": 4000,
"requires_shipping": true,
"price": 2000,
"title": "amelia - medium",
"url": "/products/amelia",
"quantity": 2,
"id": 30104012,
"grams": 200,
"sku": "",
"vendor": "the candi factory",
"image": "http://static.shopify.com/s/files/1/0040/7092/products/2766315_da1b.png?1268045506",
"variant_id": 30104012
}
http://store.myshopify.com/cart.js
哪个会给你这个：
{
"items": [
{
"handle": "aquarius",
"line_price": 6000,
"requires_shipping": true,
"price": 2000,
"title": "aquarius - medium",
