核心代码：

JSONObject jsonObject = new JSONObject(msg);int status = jsonObject.getInt("status");String msg2 = jsonObject.getString("msg");Log.e("TAG", status + "  " + msg2);JSONObject data = jsonObject.getJSONObject("data");String title = data.getString("title");String author = data.getString("author"); String content = data.getString("content");Log.e("TAG", "标题：" + title + "，作者：" + author + "，内容:" + content);
