Jmeter_Beanshell 返回值中提取参数值

Jmeter_Beanshell  返回值中提取参数值
【准备环境】:
　　①Jmeter版本：5.1，JDK：1.8
　　②前置条件：将json.jar包置于..\apache-jmeter-5.1\lib\下，并将该jar包添加到测试计划的Library中；否则会报：Typed variable declaration : Class: JSONObject not found in namespace的错误；
　　③处理器：Beanshell处理器，import      org.json.*;(一般习惯使用到什么import什么，如：import     org.json.JSONObject、import org.json.JSONAarry;)

【思路】
　　①获取请求的返回值，即Json响应；
        String response_data = prev.getResponseDataAsString();      //注意此处获取到的是String类型；
　　②利用上一步获取的字符串形式的JSON，结合Java处理Json的方法，将需要的键值提取出来；
    　　需要利用JSONObject或者JSONArray构造JSON对象。
    　　JSONObject JsonData = new JSONObject(StrData);
　　③替换某些需要变更的字段值，再将新的JSON处理为Jmeter的参数，用于下一个请求的参数化值；
    　　JsonData.put("status", "CLOSED");
    　　String NewData = JsonData.toString();
    　　vars.put("NewStrData",NewData);

【示例1-----JSONObject对象】
　　①获取到JSON对象，需要提取其中的userid值；

【示例2-----JSONArray对象】

　　①需要提取返回值中，每一个对象数组中的每一个 uuid 及 id 的键值：获取JSON对象，再提取data数组内容并获取data数组长度，最后循环提取每一个 uuid 及 id 的键值；备注：1个客服同时与10个客户聊天，在聊天开始之前，需要捞取到这10个客户的uuid(uuid)及conversationId(id)；

代码如下

 import org.json.JSONObject;
 import org.json.JSONArray;

 /*
  * 本脚本实现，jmeter从返回值中提取值，并传给参数
  * 返回是json
  * 返回是Array
 */
