如何获取JMeter响应的给定键的特定JSON值？
我想提取一些数据并将其存储为先前采样器响应的JMeter变量。在我的回答中，有许多所谓的属性，它们具有formulaName，definitionId和id。我想通过formulaName找到一个特定的属性（＆＃34; formulaName＆＃34;：＆＃34; F1＆＃34 ;;已定义的是用户定义的变量）并获取它的definitionId和id并将它们存储在一个变量，如attributeF1DefinitionId和attributeF1Id。 在问题的底部可以找到完整的JSON响应，但没有缩短它以更好地描述我的问题。
{

我们赞赏任何方法，我可以在下一步中自动完成此提取。我真正想要做的是提取几乎所有属性的definitionIds和id（通过其formulaName找到）并为它们生成使用定义的变量。公式名称保存在＆＃34;用户定义的变量＆＃34; - Set和我找到了一种用groovy迭代它的方法。
我的方法是在请求采样器中使用JSR223 - groovy后处理器，它加载数据并具有上面的响应。 但我卡住了，过滤了我特定的formulaName。
import groovy.json.*;
import org.apache.jmeter.threads.JMeterVariables;
def response = prev.getResponseDataAsString();
def json = new JsonSlurper().parseText(response)
def allAttributes = json.results.data.actionData.tabs.dynamicLayout.attributes;
完成JSON响应：

2 个答案:
答案 0 :(得分：0)
我相信你可以使用JSON Extractor轻松完成，例如你可以获得id属性＆＃34; formulaName＆＃34;是＆＃34; F1＆＃34;使用以下简单的JSON路径查询：
$..[?(@.formulaName == 'F1')].id
类似于definitionId，只需更改上面的JSON Path查询以匹配它：
$..[?(@.formulaName == 'F1')].definitionId
参考文献：
Groovy方法：
import groovy.json.JsonSlurper
def response = prev.getResponseDataAsString()
def json = new JsonSlurper().parseText(response)
def allAttributes = json.results.data.actionData.headerLayout.tabs[0].dynamicLayout.attributes
allAttributes.each { attribute ->
attribute.each { k, v -> log.info("${k}:${v}") }
}
答案 1 :(得分：0)
getJsonResponseString()返回一个字符串，其中包含问题中指定的json响应数据（“完整的json响应”），下面的groovy代码：
import groovy.json.*;
def data = getJsonResponseString()
def json = new JsonSlurper().parseText(data)
def attribute = json.results.data.actionData.tabs.dynamicLayout.attributes.first().find { attribute ->
attribute.formulaName == "F1"
}
if (!attribute) {
println "No attribute with formulaName F1 found!"
} else {
println "Results for 'F1': "
println " definitionId: ${attribute.definitionId}"
println " id: ${attribute.id}"
}
打印：
Results for 'F1':
definitionId: 1dc065a6-f071-4547-835b-603aff165754
id: ca25c1bc-5528-4730-8cc5-3a3c2ca4428b
上面代码中的json对象应该等同于示例代码中的json对象。
