使用 JMeter 从 JSON 响应中提取某些数据

Question

我正在尝试从 SmallerList 中提取所有 "cash" 值（放入列表或数组中）并将它们相互比较，然后在新请求中使用最高值。

我一直在尝试在 BeanShell PostProcessor 中编写脚本但失败了。有什么建议吗？谢谢

使用JSON Path Extractor。非常好用。

检查 this 以获取要使用的路径表达式。（向下滚动到部分 - XPath 和 JSONPath 之间的区别）

在您的情况下，$..cash 将 return 所有 cash，如下所示。 allcash 是我使用的变量。

allcash=["64,04 USD","64,04 USD","154,04 USD","624,04 USD"]
allcash_1=64,04 USD
allcash_2=64,04 USD
allcash_3=154,04 USD
allcash_4=624,04 USD
