由Beanshell在jmeter中从response rest服务获取第一个json对象

我从我的web服务获得此JSON响应：

[
    {
        "type": "022",
        "sendDate": "2020-11-09 12:43:07",
        "message": "test1",
        "id": 8035,
    },
    {
        "notificationType": "023",
        "sendDate": "2020-11-09 11:40:02",
        "message": "test2 ",
        "id": 8034,
    },...
]

现在，通过JMeter中的Beanshell，我想将第一个id传递到新请求中，因此在JSR223后处理器中，我编写了如下简单打印：

import com.eclipsesource.json.*;
String jsonString = prev.getResponseDataAsString();
log.info("value=" + jsonString);
JsonArray inbox =  Json.parse(jsonString).asArray();
//String id_BSH = ((JSONObject) storeArray.get(0)).getAsString("id");
//vars.put("id_BSH", pickup);

但我有一个错误：

我听说，您可以使用Groovy的类将第一个ID存储到一个变量中，并使用以下一行代码：

vars.put("id_BSH", new groovy.json.JsonSlurper().parse(prev.getResponseData()).get(0).id as String)

您是否将最小json jar添加到JMeter类路径？是的，我将

最小json

添加到lib JMeter@user7294900Jar不在lib folder中我必须放置的文件夹是什么@user7294900

自JMeter 3.1以来，我们建议从BeanShell切换到JSR223测试元素

。我使用的是JSR223@dmitri您使用的是带有BeanShell语言的JSR223测试元素，您应该使用groovy
