My questions are: 我的问题是：
- Why is/are the JSON strings getting changed on each iteration? 为什么每次迭代都更改JSON字符串？
- Is there a way to simply make the inbound JSON string as generic programmatically in order to get this thing working? 是否有一种方法可以简单地以编程方式使入站JSON字符串通用，以使此功能正常工作？
- If there is a way, what is it or are there examples (which I am unable to find) out there that can assist? 如果有办法，那是什么？有没有可以帮助您的例子（我找不到）？

Found a workaround. 找到了解决方法。 Apparently, I was trying to hard to get this accomplished by over complicating the issue. 显然，我试图通过使问题变得过于复杂来努力实现这一目标。
