public static String getHtml(String tempurl,String code){    

try{   
URL url = new URL(tempurl);    
HttpURLConnection conn = (HttpURLConnection)url.openConnection();    
conn.connect();   
InputStream is = conn.getInputStream();   
BufferedReader br = new BufferedReader(new InputStreamReader(is,code));   
String line="";   
StringBuffer resultBuffer = new StringBuffer();   

while((line = br.readLine())!=null){     

resultBuffer.append(line);    

}    

br.close();    

is.close();    

conn.disconnect();   

return resultBuffer.toString();  

}
