我需要编写一个简单的 LogicApp，它连接到 http 端点，接收一些 JSON，循环遍历 JSON 消息，并根据消息中的值将其分块提交到不同的 http 端点。
在这样做时，我得出的结论是，For Each 循环内的条件始终评估循环之前的条件并执行与循环之前的结果匹配的路径，即使结果应该已经更改，因为一些变量已在循环。
我已经成功地用下面的例子来说明这个问题。

我希望下面的 LogicApp 执行循环三次，每次评估条件并仅执行一次数组插入，其中 TestArray 包含一个条目
{
"key":"value1"
}
字符串 TestStr 的值为“not”
但实际结果似乎有所不同 - TestArray 包含 FullArray 中的所有三个条目，而 TestStr 是“XXXX”
我在这里缺少什么？有什么解决方法吗？
