Java中的URCPonnection編碼

我試圖連接到google的趨勢並解析他們的迴應。我有這樣的代碼。Java中的URCPonnection編碼

String urlstr = "http://www.google.com/trends/fetchComponent?q=seattle&cid=TIMESERIES_GRAPH_0&export=3"; 

    URL url; 

    String responsestr = null; 
    try { 
     url = new URL(urlstr); 
     //Reader reader = new InputStreamReader(url.openStream(),"UTF-8"); 
     URLConnection connection = url.openConnection(); 
     connection.setRequestProperty("Accept-Charset", "UTF-8"); 
     InputStream response = connection.getInputStream(); 
     Reader reader = new InputStreamReader(response); 
    }catch(Exception e){}

可以確認網址是否正確，只需複製粘貼網址到瀏覽器，不過，雖然我的代碼通過，並且與谷歌的連接，這對谷歌的話說，一邊返回一個錯誤，它可以不處理我的請求。我在編碼或URL中做錯了什麼，或者我如何設置URLConnection。任何幫助，將不勝感激！

你的代碼是我的系統上正常工作。你得到什麼異常？ – 2014-11-25 04:58:35

我剛剛發現谷歌放在查詢的數量上限，如果查詢超過閾值，阻止你的IP地址......我想這是沒有好的解決方案:( – wasabi 2014-11-25 05:14:44

我可能嵌入了可嵌入版本的代碼到一個網站來解決這個問題？ – wasabi 2014-11-25 05:15:29

獲得如下響應。

public static void main(String[] args) { 
     String urlstr = "http://www.google.com/trends/fetchComponent?q=seattle&cid=TIMESERIES_GRAPH_0&export=3"; 
     URL url; 
     try { 
      url = new URL(urlstr); 
      // Reader reader = new InputStreamReader(url.openStream(),"UTF-8"); 
      URLConnection connection = url.openConnection(); 
      connection.setRequestProperty("Accept-Charset", "UTF-8"); 
      BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream())); 
      String inputLine; 
      while ((inputLine = in.readLine()) != null) 
       System.out.println(inputLine); 
      in.close(); 
     } catch (Exception e) { 
      System.out.println(e); 
     } 
    }
