Jmeter提取复杂json字符串

 设置：

 设置：

import com.alibaba.fastjson.*;

//获取从上一个请求返回的数据
String rspData = prev.getResponseDataAsString();
//把从结果中得到的json数据转成json对象
JSONObject dataObj = JSONObject.parseObject(rspData);

//因为 loanList 是在data中，所以还要得到data对象
JSONObject jsonData = dataObj.getJSONObject("data");

//data对象的loanList转成json 数组
JSONArray loanLists = jsonData.getJSONArray("loanList");

//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
JSONObject loanObject;
String loanNo = null ;
String loanState = null;
String loanAmt= null;
for (int i = 0; i < loanLists.size(); i++) {
    loanObject = (JSONObject) loanLists.get(i);
    loanState = loanObject.getString("loanState");
    if (loanState.equals("RP")) {
        loanNo = loanObject.getString("loanNo");
        loanAmt = loanObject.getString("loanAmt");
        break;
    }
}
//log.info("----------------------------------------" + loanNo);        
vars.put("RPLoanNo",loanNo);
vars.put("RPLoanAmt",loanAmt);
