上面的写法虽然能获取到数据，但思路不是很清晰，下面是推荐的写法:

java.nei.HttpURLConnection类是另外一种访问HTTP资源的方式。HTTPURLConnection类具有完全的访问能力，可以取代HttpGet和HttpHost类。

 1 private String getData(){
 2         String t="";
 3         try
 4         {
 5             InputStream is = getNetInputStream(myurl);
 6             InputStreamReader isr = new InputStreamReader(is, "utf-8");
 7             BufferedReader br = new BufferedReader(isr);
 8             String s = null;
 9             while ((s = br.readLine()) != null)
10             {
11                 String[] data = s.split(">");
12                 if (data.length > 1)
13                 {
