InputStreamReader in = new InputStreamReader(connection.getInputStream())获取不到值

[qq443125744]

try {
String strURL = "http://localhost:8080/ARCloudServer-0.1.0/advertise/";
URL url = new URL(strURL);

HttpURLConnection urlConn = (HttpURLConnection) url.openConnection();
InputStreamReader in = new InputStreamReader(urlConn.getInputStream());
BufferedReader bufferReader = new BufferedReader(in);
String result = "";
String readLine = null;
while ((readLine = bufferReader.readLine())!=null){
result +=readLine;
}
in.close();
urlConn.disconnect();

} catch (IOException e) {
e.printStackTrace();
}
如代码所示：在HttpURLConnection转换为字符流的时候得到的是一个空值，怎么解决啊？

先用正常方法试一下能不能得到需要的内容, 然后再用 InputStreamReader .
