在调用Tumblr post reblog api时获得401（未授权）

Question

我在调用Tumblr post reblog api时获得401状态，其他tumblr api工作正常。

我遵循了一些Stackoverflow链接但无法搭乘它。

constantly-getting-401-when-trying-to-post-to-tumblr-blog

tumblr-oauth-image-post-gives-me-401-invalid-oauth-credentials

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);

错误输出：

10-21 21:48:31.851: W/DefaultRequestDirector(30729):
Authentication error: Unable to respond to any of these challenges: {}
