我不知道该如何解决。 请帮助我，我是中国人， 所以我的英语不好，我希望你知道我的意思。 这是我的代码：

    try {
        final URL url = new URL(
                \"https://www.google.com/accounts/ClientLogin\");
        final URLConnection urlConn = url.openConnection();
        urlConn.setDoInput(true);
        urlConn.setDoOutput(true);
        urlConn.setUseCaches(false);
        urlConn.setRequestProperty(\"Content-type\",\"application/x-www-form-urlencoded\");

        final DataOutputStream cgiInput = new DataOutputStream(
                urlConn.getOutputStream());

        String content = null;
        content = \"accountType=\" + \"HOSTED\" + \"&Email=\" + email
                + \"&Passwd=\" + password + \"&service=\" + \"wise\" + \"&source=\"
                + applicationName;
        cgiInput.writeBytes(content);
        cgiInput.flush();
        cgiInput.close();

        if (urlConn instanceof HttpURLConnection) {
            final boolean status = ((HttpURLConnection) urlConn)
                    .getResponseCode() == 200;
            if (status) {
                System.out.println(\"i\'m in\");
                SpreadsheetService service = new 
                        SpreadsheetService(applicationName);
                URL metafeedUrl = new 
                        URL(\"https://spreadsheets.google.com/feeds/spreadsheets/private/full\");
                SpreadsheetFeed feed = service.getFeed(metafeedUrl,SpreadsheetFeed.class);

                List<SpreadsheetEntry> spreadsheets = feed.getEntries();
                for (int i = 0; i < spreadsheets.size(); i++) {
                  SpreadsheetEntry entry = spreadsheets.get(i);
                  System.out.println(\"\\t\" + entry.getTitle().getPlainText());
                }
            }
        }

    } catch (MalformedURLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (ServiceException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}
