Jmeter_Beanshell 返回值中提取參數值

Jmeter_Beanshell  返回值中提取參數值
【准備環境】:
　　①Jmeter版本：5.1，JDK：1.8
　　②前置條件：將json.jar包置於..\apache-jmeter-5.1\lib\下，並將該jar包添加到測試計划的Library中；否則會報：Typed variable declaration : Class: JSONObject not found in namespace的錯誤；
　　③處理器：Beanshell處理器，import      org.json.*;(一般習慣使用到什么import什么，如：import     org.json.JSONObject、import org.json.JSONAarry;)

 

 

【思路】
　　①獲取請求的返回值，即Json響應；
        String response_data = prev.getResponseDataAsString();      //注意此處獲取到的是String類型；
　　②利用上一步獲取的字符串形式的JSON，結合Java處理Json的方法，將需要的鍵值提取出來；
    　　需要利用JSONObject或者JSONArray構造JSON對象。
    　　JSONObject JsonData = new JSONObject(StrData);
　　③替換某些需要變更的字段值，再將新的JSON處理為Jmeter的參數，用於下一個請求的參數化值；
    　　JsonData.put("status", "CLOSED");
    　　String NewData = JsonData.toString();
    　　vars.put("NewStrData",NewData);

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

 

 

 

 【示例2-----JSONArray對象】

　　①需要提取返回值中，每一個對象數組中的每一個 uuid 及 id 的鍵值：獲取JSON對象，再提取data數組內容並獲取data數組長度，最后循環提取每一個 uuid 及 id 的鍵值；備注：1個客服同時與10個客戶聊天，在聊天開始之前，需要撈取到這10個客戶的uuid(uuid)及conversationId(id)；

 

 

 

 

代碼如下

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

/*
 * 本腳本實現，jmeter從返回值中提取值，並傳給參數
 * 返回是json
 * 返回是Array
*/
