使用了gson解析数据

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 {

JsonArray list = json.get("proxy").getAsJsonArray();

System.out.println("Port: " + String.valueOf(port));
}
} catch (JsonIOException e) {
e.printStackTrace();
}
}
