在 JMeter 中捕获值的正则表达式

Question

在Jmeter中，想要从下面的json响应代码中捕获POD的id。尝试 $..result[*].id 并显示所有 ID，包括 Value1、Value2 中的一次。但我的要求只是捕获PODID，以便可以在下一个请求中传递它。 是否可以将 PODID 保存在数组中并在下一个请求中发送它们？

Answer 1

您正在使用

..

operator，这意味着“深度扫描”，因此它将返回所有

id

属性值，无论它们位于何处。

您需要将

id

属性的提取限制为仅

result

JSON 数组 的直接子级。比如：

result.*.id
