如何在JMeter中使用groovy将JSON响应从http请求传递到jsr223断言？

Question

我有一个API返回以下结果：

{"success":true,
  "error":null,
  "data": {"EmpId":444,"ProfileNo":0,"ProfileName":"xya","Rank":0,"ScoreValue":0,"CompanyEmpID":"A25842"}}

import groovy.json.JsonSlurper;
JsonSlurper JSON = new JsonSlurper ();

def expected = new groovy.json.JsonSlurper().parseText(vars.get('Employee 
data'))
def actual = new 
groovy.json.JsonSlurper().parse(prev.getResponseData({"success":true,
"error":null,
"data":

{"EmpId":444,
 "ProfileNo":0,
 "ProfileName":"xya","Rank":0,"ScoreValue":0,"CompanyEmpID":"A25842"}})

 if (expected != actual) {
 AssertionResult.setFailure(true)
 AssertionResult.setFailureMessage('Mismatch between expected and actual 
 JSON')
  }

断言错误：true断言失败：false断言失败消息：javax.script.scriptexception:org.codehaus.groovy.control.multipleCompilationerrorsexception:startup failed:script20.groovy:10:预期“}”，发现“：”@第10行，第81.rev.getResponseData（{“success”：true,^

1错误

正确的代码如下所示：

def expected = new groovy.json.JsonSlurper().parseText('{"success":true,\n' +
        '  "error":null,\n' +
        '  "data": {"EmpId":444,"ProfileNo":0,"ProfileName":"xya","Rank":0,"ScoreValue":0,"CompanyEmpID":"A25842"}}')

def actual = new groovy.json.JsonSlurper().parse(prev.getResponseData())

if (expected != actual) {
    AssertionResult.setFailure(true)
    AssertionResult.setFailureMessage('Mismatch between expected and actual JSON ')
}

但是，如果使用这种方法比较嵌套的JSON对象，它只适用于第一级值--您将得到假阳性结果，因此最好选择执行“深度扫描”的Jackson或JSONAssert库，请查看使用JMeter比较REST API响应的最简单方法文章了解更多细节。
