Why can not get weather like this to get the data.

 
public InputStream getInputStreamFromUrl (String urlStr) 
throws MalformedURLException, IOException {
url = new URL (urlStr); 
HttpURLConnection urlConn = (HttpURLConnection) url.openConnection (); 
urlConn.setConnectTimeout (15000); 
urlConn.setRequestMethod ("GET"); 
InputStream input = urlConn.getInputStream (); 
return input; 
} 

 
public String download (String urlStr) {
StringBuffer sb = new StringBuffer (); 
String line = null; 
BufferedReader buffer = null; 
InputStream input = null; 

try {
input = this.getInputStreamFromUrl (urlStr); 
buffer = new BufferedReader (new InputStreamReader (input)); 
while ((line = buffer.readLine ())! = null) {
sb.append (line); 
} 
} Catch (MalformedURLException e) {
e.printStackTrace (); 
} Catch (IOException e) {
e.printStackTrace (); 
} Finally {
try {
if (buffer! = null) {
buffer.close (); 
buffer = null; 
} 
if (input! = null) {
input.close (); 
input = null; 
} 
} Catch (IOException e) {
e.printStackTrace (); 
} 
} 

return sb.toString (); 
} 

download ("http://m.weather.com.cn/data/101190101.html");

A few days ago, no problems, now is get less data<-! Main posts under Banner (D4) -><-! Posts under the main text (D5) ->
Reply:
HttpURLConnection urlConn = (HttpURLConnection) url.openConnection ();
This place urlConn.connect (); This is not normally connected to the network can add?
