使用URLConnection获取页面返回的xml数据

public static void main(String[] args) throws Exception {

String path="http://flash.weather.com.cn/wmaps/xml/hubei.xml";
URL url = new URL(path);//获得url对象
HttpURLConnection conn = (HttpURLConnection)url.openConnection();  //创建URLConnection连接
conn.setReadTimeout(5*1000);
conn.setRequestMethod("GET");
BufferedReader bufr=new BufferedReader(new InputStreamReader(conn.getInputStream(),"UTF-8"));//设置文件输入流的编码，和url的编码一致
String lines="";
String result="";
while ((lines=bufr.readLine())!=null) {
result+=lines;
}
System.out.println(result);
}

public static void main(String[] args) throws Exception {

String path="http://wthrcdn.etouch.cn/WeatherApi?citykey=101010100";
URL url = new URL(path);
HttpURLConnection conn = (HttpURLConnection)url.openConnection();
conn.setReadTimeout(5*1000);
conn.setRequestMethod("GET");
BufferedReader bufr=new BufferedReader(new InputStreamReader(new GZIPInputStream(conn.getInputStream()),"UTF-8"));//使用GZIPInputStream解压缩
String lines="";
String result="";
while ((lines=bufr.readLine())!=null) {
result+=lines;
}
System.out.println(result);
