Jmeter提取复杂json字符串

 1 import com.alibaba.fastjson.*;
 2 
 3 //获取从上一个请求返回的数据
 4 String rspData = prev.getResponseDataAsString();
 5 //把从结果中得到的json数据转成json对象
 6 JSONObject dataObj = JSONObject.parseObject(rspData);
 7 
 8 //因为 loanList 是在data中，所以还要得到data对象
 9 JSONObject jsonData = dataObj.getJSONObject("data");
10 
11 //data对象的loanList转成json 数组
12 JSONArray loanLists = jsonData.getJSONArray("loanList");
13 
14 //通过for循环得到数组的中的对象，然后根据属性得到相应的值
15 JSONObject loanObject;
16 String loanNo = null ;
17 String loanState = null;
18 String loanAmt= null;
19 for (int i = 0; i < loanLists.size(); i++) {
20     loanObject = (JSONObject) loanLists.get(i);
21     loanState = loanObject.getString("loanState");
22     if (loanState.equals("RP")) {
23         loanNo = loanObject.getString("loanNo");
24         loanAmt = loanObject.getString("loanAmt");
25         break;
26     }
27 }
28 //log.info("----------------------------------------" + loanNo);        
29 vars.put("RPLoanNo",loanNo);
30 vars.put("RPLoanAmt",loanAmt);
