jd（按关键字搜索商品）API接口
为了进行电商平台 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jd应用注册一个应用程序键（App Key) 。
3）下载jdAPI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jd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jd API应用开发的关键流程，其中通过jd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。jd的API很多，不过都分为了好几个领域，慢慢就会了解深入了。
