我正在尝试阅读 oktaData.signIn.statetoken 和 okta_key。我正在使用 JMeter 和 JSR233 后处理器（Groovy）。为了评估性能，我还想在 K6/Java Script 中读取上述值。

使用下面的代码，我可以在 Java Script (K6) 中成功读取值

 let body = response.body;
 let rawDataAfterConversion = unicodetochar(body.match(/oktaData = (.*);/)[1]);
 let oktaData = eval('(' + rawDataAfterConversion + ')');
 let oktaStatetoken = oktaData.signIn.statetoken;
 let okta_key_param = 'okta_key=';
 let okta_key = oktaData.signIn.relayState.substring(oktaData.signIn.relayState.indexOf(okta_key_param) + okta_key_param.length);

但是，我在 JMeter 中读取相同值时遇到问题。

以下是我尝试过的几件事。

def responseBody = prev.getResponseDataAsstring()
def match = responseBody =~ /oktaData = (.*);/

if (match.find()) {
    def value = match.group(0)
    log.info('------------------')
    log.info('a value=' + value) 
    log.info('------------------')
}
else
{
    vars.put('rawData',"ERROR")
}


vars.put('oktaData',(prev.getResponseDataAsstring() =~ /oktakey=(\w+);//)[0][1])

不幸的是，一切都不是很好。
