当密钥未知时，如何从jmeter中的json中提取值？

假定您具有以下格式的响应：

{  "data": {    "assets": {      "sadsad12dwqqwe": "asda1212312",      "asdasd1213123": "asdas2131231"    }  }}

您可以使用JSR223PostProcessor
和以下代码提取键名称：

new groovy.json.JsonSlurper().parse(prev.getResponseData()).data.assets.eachWithIndex{ def node, int idx ->    log.info('Key ' + idx + '=' + node.getKey())    vars.put('key_' + idx, node.getKey())}

It will print key names into jmeter.log file and create JMeter Variables
like:

- `${key_1}`- `${key_2}`- etc.

holding the required “key” values.
