java – Google Reader API身份验证

RestTemplate restTemplate = new RestTemplate();
List<HttpMessageConverter<?>> converters =
   new ArrayList<HttpMessageConverter<?>> restTemplate.getMessageConverters());
converters.add(new PropertiesHttpMessageConverter());
restTemplate.setMessageConverters(converters);

Properties result = preparePostTo(AUTHENTICATION_URL)
                .using(restTemplate)
                .expecting(Properties.class)
                .withParam("accountType","HOSTED_OR_GOOGLE")
                .withParam("Email",email)
                .withParam("Passwd",password)
                .withParam("service","reader")
                .withParam("source","google-like-filter")
                .execute();
String token = (String) result.get("Auth");

现在我有令牌像：DQAAAI … kz6Ol8Kb56_afnFc(超过100个字符长度)并尝试获取网址：

URL url = new URL(LIKERS_URL + "?i=" + id);
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.addRequestProperty("Authorization","GoogleLogin Auth=" + token);
return url;

但是当我使用此URL获取内容时,我得到401客户端错误异常.它能是什么？

根据这个问题Google Reader Authentication problem一切都应该没问题.

我可以将内容简单地粘贴到浏览器中.
