使用了gson解析数据

package online.geekgalaxy.test;import java.io.BufferedReader;import java.io.InputStreamReader;import java.net.URL;import java.net.URLConnection;import com.google.gson.*;public class jsonAPI {    public static void main(String[] args) throws Exception {        //外接口路径        String urlStr="http://31f.cn/api/httpAll/";        //链接URL        URL url=new URL(urlStr);        //返回结果集        StringBuffer document = new StringBuffer();        //创建链接        URLConnection conn = url.openConnection();        //读取返回结果集        BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream(),"utf-8"));        String line = null;        while ((line = reader.readLine()) != null){            document.append(line);        }        reader.close();        System.out.println(document);        JsonParser parse =new JsonParser();  //创建json解析器        try {            JsonObject json=(JsonObject) parse.parse(document.toString());  //创建jsonObject对象            JsonArray list = json.get("proxy").getAsJsonArray();            for (JsonElement element:list) {                JsonObject childjson = (JsonObject) parse.parse(element.toString());                String ip = childjson.get("ip").getAsString();                Integer port = childjson.get("port").getAsInt();                System.out.println("IP: " + ip);                System.out.println("Port: " + String.valueOf(port));            }        } catch (JsonIOException e) {            e.printStackTrace();        }    }}
