Jmeter BeanShell PostProcessor提取json数据

需求：提取sample返回json数据中所有name字段值，返回的json格式如下： 
{“body”:{“apps”:[{“name”:”111”},{“name”:”222”}]}} 
jmeter中添加后置处理器BeanShell PostProcessor 
 

import org.json.*;

String response_data = prev.getResponseDataAsString();
JSONObject data_obj = new JSONObject(response_data);
String apps_str = data_obj.get("body").get("apps").toString();
JSONArray apps_array = new JSONArray(apps_str);
String[] result = new String[apps_array.length()];
for(int i=0;i<apps_array.length();i++){
    JSONObject app_obj = new JSONObject(apps_array.get(i).toString());
    String name = app_obj.get("name").toString();
    result[i] = name;
}
vars.put("result", Arrays.toString(result));
