现在想在对象里再set进去俩个字段，两个字段都保存的固定的值，应该怎么写

Answer 1

1、首先这个JSONObject对象你是能获取到的对吧，假如是jsonObject
2、通过这个方法jsonObject.getJSONObject("emp_evn_rescue")获取到emp_evn_rescue的JSONObject对象，假如是jsonObject1
JSONObject jsonObject1=jsonObject.getJSONObject("emp_evn_rescue")
3、通过put的方法放进去你想要的两个字段，假如是user_id,user_name
jsonObject1.put("user_id",1);
jsonObject1.put("user_name","张三");
