jmeter如何取出id，id在一个json的，对像里包含对像，再包含一个数组，数组里再包含一个对像
比如说我们要取以下json里的evaluateTaskId，怎么办呢？如果这个evaluateTaskId，有多个，不至一个，怎么办？
1，首先要分析这个json的构成
2，再根据这个组成，一步一步去取这个id
3，先写好这个接口的http请求，
4，在这个请求上加一个后置处理器
5，再写上beanshell就ok

jmeter截图如下：
beanshell代码如下：
/*JMETER,BEANSHELL循环遍历值，随机取数组当中一个值*/

import java.util.List;

String response_data = prev.getResponseDataAsString();
String request_data = prev.getQueryString();
String tname = prev.getThreadName();
log.info("==========="+ response_data);
JSONObject data_obj = new JSONObject(response_data);
//得到数组records，并转成字符串
String apps_str = data_obj.get("result").get("list").toString();
log.info("=======数组的值为： "+ apps_str);
JSONArray apps_array = new JSONArray(apps_str);
for(int i=0;i
String interfaceId = app_obj.get("interfaceId").toString();
log.info("=============循环打印interfaceId的值为" + interfaceId );
}
/*随机得到数组内的一个值，并把值传到下个接口*/
int ranLen = apps_array.length();
Random r=new Random();
int i1=r.nextInt(ranLen); //生成[0, apps_array.length()]区间的整数
log.info(">>>>>>>" + i1+"" );
JSONObject app_obj = new JSONObject(apps_array.get(i1).toString());
//从app_obj这个对像中获得coinChange,转化成字符串
String interfaceId = app_obj.get("interfaceId").toString();
vars.put("interfaceId",interfaceId);
log.info("随机得到的值为：" + interfaceId );
