【拼多多API 开发系列】百亿补贴商品详情接口，代码封装

为了进行电商平台 PDD 的API开发，首先我们需要做下面几件事情。
1）开发者注册一个账号
2）然后为每个 PDD 应用注册一个应用程序键（App Key) 。
3）下载 PDD API的SDK并掌握基本的API基础知识和调用
4）利用SDK接口和对象，传入AppKey或者必要的时候获取并传入SessionKey来进行程序开发。
5）利用PDD平台的文档中心和API测试工具，对接口进行测试。从而了解返回信息，方便程序获取。
以上是一般 PDD API应用开发的关键流程，其中通过 PDD文档中心和API测试工具，进行概念了解和接口信息查询很重要。因为这些数据就是我们需要在逐步显示出来的。 PDD 的API很多，不过都分为了好几个领域，慢慢就会了解深入了。

 item_get-根据ID取商品详情接口
通过代码封装该接口可以拿到商品标题，商品价格，商品促销信息，商品优惠价，商品库存，sku属性，商品图片，desc图片，desc描述，sku图片，sku描述，商品规格，商品销量，商品重量，商品尺寸，商品列表，店铺所有商品，商品详情属性描述等页面上有的参数均可以拿到。
