/**
-
数据形式:{"id":1,"isNo":false,"data":[{"id":1,"name":"张三"},{"id":2,"name":"李四"},{"id":2,"name":"王五"}]}

public static List<Map<String, String>> getJSONObject(String path) throws Exception {
List<Map<String, String>> list = new ArrayList<Map<String, String>>();
Map<String, String> map = null;
URL url = new URL(path);
// HttpURLConnection可以从网络中获取数据.
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
//
设置超时时间
conn.setConnectTimeout(5 1000);
conn.setRequestMethod("GET");//这个应该都知道是干嘛的,默认是GET
if (conn.getResponseCode() == 200) {// 判断请求码,不是200则为请求失败
InputStream is = conn.getInputStream(); // 获取输入流
byte[] data = readStream(is);
String json = new String(data);JSONObject jsonObject=new JSONObject(json); //返回的数据形式是一个Object类型 int total=jsonObject.getInt("id"); Boolean success=jsonObject.getBoolean("isNo"); JSONArray jsonArray = jsonObject.getJSONArray("data");//用getJSONArray获取数组 for (int i = 0; i < jsonArray.length(); i++) { JSONObject item = jsonArray.getJSONObject(i); int id = item.getInt("id"); String name = item.getString("name"); map = new HashMap<String, String>(); map.put("id", id + ""); map.put("name", name); list.add(map); } } return list;
}
此为{"id":1,"isNo":false,"data":[{"id":1,"name":"张三"},{"id":2,"name":"李四"},{"id":2,"name":"王五"}]}
类型的JSON,其他类型的都可以通过此方法获得,转换时举一反三就可以了。<p>版权声明:本文为博主原创文章,未经博主允许不得转载。</p>
