         //Open connection to URL for reading.
        
            BufferedReader reader=new BufferedReader(new InputStreamReader(url.openStream())); 
            //Read page into buffer.
            String line; 
            StringBuffer pageBuffer = new StringBuffer(); 
            while ((line = reader.readLine()) != null) { 
                 pageBuffer.append(line); 
            }

        } catch (Exception e) {
         log.error("connect url "+curl+" failure:"+e.getMessage());
