解析json格式的数据

假设服务器端返回的json格式数据是：

{
	deptId:'1', 
	deptName:'dept1', 
	branch:{
		branchId:'25', 
		branchName:'GuangFen'
	}, 
	users:[
		{
			userId:'1001', 
			userName:'user1'
		}, 
		{
			userId:'1002', 
			userName:'user2'
		}
	]
}

 

获取服务器端数据并解析：

//http请求的URL地址
String url = "http://10.193.16.40:7777/android_web/testServlet";

String result = HttpClientUtils.handlerGet(url);

if(StringUtils.isNotEmpty(result)){
	//将json格式的字符串转成json对象
	JSONObject dept = new JSONObject(result);
	
	//取单个属性值
	System.out.println("deptId = " + dept.getString("deptId"));
	System.out.println("deptName = " + dept.getString("deptName"));
	
	//取json对象
	JSONObject branch = dept.getJSONObject("branch");
	System.out.println("branchId = " + branch.getString("branchId"));
	System.out.println("branchName = " + branch.getString("branchName"));
	
	//取json数组
	JSONArray users = dept.getJSONArray("users");
	for(int i=0;i<users.length();i++){
		JSONObject user = users.getJSONObject(i);
		System.out.println("userId = " + user.getString("userId"));
		System.out.println("userName = " + user.getString("userName"));
	}
}
