亚马逊MWS开发套路演示
MWS是商城网络服务的缩写，具体介绍看这里http://docs.developer.amazonservices.com/zh_CN/dev_guide/DG_IfNew.html。MWS就是一组API，提供给开发者调用，实现卖家的数据上传、获取报告、库存、订单等。上面的贴出来的链接里有关于MWS开发者的详细说明，建议先好好通读下“程序员开发指南”，先了解下需要怎么去拼接请求地址和必传参数，否则会走很多弯路。
在构造一个请求MWS的url之前，你必须得有一个卖家ID（merchantId），如果你自己就是卖家，那么就拿你的卖家ID去注册一个开发者账号，亚马逊会给你一个开发者ID、一个访问秘钥ID（accessKeyId）和一个访问秘钥（secretAccessKey），我们只需要用到3个信息：merchantId、accessKeyId和secretAccessKey。如果卖家是你的朋友，那么同上，由他去注册开发者账号，把这3个信息给你即可。如果是第三方开发者（他已经自己注册了开发者账号），那么卖家需要拿第三方开发者的账号进行授权，授权他能访问卖家账号，这种情况需要把授权令牌（sellerDevAuthToken）拼接到请求地址中。最后作为开发者，你还得知道卖家的MWS究竟是在哪个国家开的，是在美国，欧洲，还是中国？每个地方对应不同的链接地址。
亚马逊 MWS 文档 » 程序开发员指南 » 亚马逊 MWS Scratchpad（测试工具），点开之后有不同国家MWS对应测试链接，可以要求把对应的参数输进去，看下API返回信息对不对。假设我的店开在中国区，那么就到https://developer.amazonservices.com.cn/这里去点开“导航 -> 亚马逊 MWS Scratchpad（测试工具）”。如果是国外的MWS会慢一些，毕竟传输路径比较长嘛。假如我现在是在北美注册的卖家账号，那么点开https://developer.amazonservices.com（等待n秒） -> Amazon MWS Scratchpad -> SellerId填merchantId、AWSAccessKeyId填accessKeyId、Secret Key填secretAccessKey -> 最后选对应API操作后，点击提交即可。
如果你想下载客户端代码，直接点开“API与文档 -> 报告（随便点开一个接口即可）-> Java客户端（选择你想要的语言）-> download”。下好了代码直接就拿来主义好了，改改上面的请求字段就可以跑起来了，看一下获取报告条数的API：
