使用JMeter从JSON响应中提取某些数据

我试图从SmallerList（进入列表或数组）中提取所有“现金”值，并将它们相互比较，然后在新的请求中使用最高值。使用JMeter从JSON响应中提取某些数据

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

请显示您到目前为止所尝试的内容。 JSON路径提取器可能是一个很好的方法。 http://jmeter-plugins.org/wiki/JSONPathExtractor/ – RaGe

不能比较数据与路径提取器。 – tipi

使用JSON Path Extractor。这是非常容易使用。

检查要使用的路径表达式的 this。（向下滚动到XPath和JSONPath之间的区别）

对于您的情况，$..cash将返回所有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

我这样做后，我怎么能得到小列表的索引。例如，如果我选择allcash_4我需要发送第四个列表的索引作为回应 – tipi
