Android 调用Tumblr post reblog api时获取401（未授权）

调用Tumblr post reblog api时，我得到了401状态，其他Tumblr api工作正常

我跟随了一些Stackoverflow链接，但没能骑上它

我的代码片段：

String url = String.format(REBLOG_URL, blogName);

HttpPost request = new HttpPost(url);

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("id", postId));
nameValuePairs.add(new BasicNameValuePair("reblog_key", reblogKey));
nameValuePairs.add(new BasicNameValuePair("comment", comment));
nameValuePairs.add(new BasicNameValuePair("api_key", consumerKey));

request.setEntity(new UrlEncodedFormEntity(nameValuePairs, "UTF-8"));

CommonsHttpOAuthConsumer consumer = new CommonsHttpOAuthConsumer(consumerKey, secretKey);
                                consumer.setTokenWithSecret(mDataStore.getAccessToken(mUserSequenceId),
                    mDataStore.getTokenSecret(mUserSequenceId));
consumer.sign(request);

String response = makePostRequest(request);

L.d(TAG, "postReblog Response : " + response);

提前谢谢
