json生成、解析

这是用org.json解析json的一个测试类，需要引入对应的两个包
import org.json.JSONArray;
import org.json.JSONObject;

例子中的json字符串有点长，是一个数组原型

		try {
			StringBuffer jsonString = new StringBuffer();
			 			 jsonString.append("[{'subdepts': [{'subdepts': [], 'name': '总经理', 'members': [{'loginname': 'songguangbin', 'sex': '男', 'phone': ['2357.0'], 'wechat': '', 'password': '123qwe', 'qq': 0,
