筆記紀錄一下

底下可以直接parse網頁成字串

再看要怎樣分析

                return;
            }
          
            BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String urlString = "";
            String current;
            while((current = in.readLine()) != null){

            }
            System.out.println(urlString);
        } catch (MalformedURLException ex) {
            System.out.println(ex.toString());
        } catch (IOException ex) {
            System.out.println(ex.toString());
        }

      
    }
