【背景】
折腾：
过程中，想要试试ResponseGroup的Variations。
【折腾过程】
1.有了：
【整理】C#版的AWS的ResponseGroup的VariationSummary示例代码
的经验后，就可以直接去获取产品的Variation的parent的ASIN，然后直接去获得其中的所有的，全部的variations的信息了。
2. 完整代码如下：

很明显，其中的Variations下面：
通过TotalVariations知道有4个variation；
对应的4个Item，每个都有：
ASIN
SmallImage/MediumImage/LargeImage
等等详细的信息。
【总结】
给定某个产品ASIN：
如果是child的ASIN：则需要先去获得对应的ParentASIN；
如果本身是parent的ASIN，则可以直接其获得：所有的variation的详细的信息；
更多信息可参考：
