HttpURLConnection响应的JSON 数据部全是怎么会事？在线等!!!!!

[hewei5894]

代码是这样的：
try{
String url= "http://m.qzone.qq.com/cgi-bin/new/msgb_output_page?uin=1234567&start=1&json=1&num=4";
URL login = new URL(url);
HttpURLConnection conn =null;

conn =(HttpURLConnection)login.openConnection();//openConnection();//打开链接
HttpURLConnection.setFollowRedirects(true);
// conn.setRequestProperty( "username ", "username ");
// conn.setRequestProperty( "password ", "userpwd ");

conn.setDoOutput(true);
conn.setRequestProperty("User-Agent","Mozilla/4.0 (compatible; MSIE 6.0; Windows 2000)");
conn.setRequestMethod( "GET"); //
BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String text ="";
while( null != br.readLine()){
text = text +br.readLine();
System.out.println(br.readLine());
}
}catch(Exception e){}
用浏览器 返回的数据就是正常的、

是我打印出来的内容 不全， 只有部分

String text2
while( (text2= br.readLine())!=null){
text = text +text2;

}
System.out.println(text);

实际上text一般是用stringbuffer或 stringbuilder的
