Anybody can please help in Android + Twitter Integration using OAuth.

我已经在http://github.com/brione/Brion-Learns-OAuth 并收到下面列出的错误，当我发布状态更新时...

I already worked on http://github.com/brione/Brion-Learns-OAuth and getting the error listed below, when I am posting status update...

我成功通过 OAuth 身份验证并获取 user_secret 和 user_token 并存储在首选项中...

I succeed with OAuth Authentication and getting user_secret and user_token and stored in preferences...

所以问题在于使用 OAuth 标头进行 http 发布...

So the issue is with http posting using OAuth header...

而我的 Http Post 方法如下:

and My Http Post Method is as :

private class PostTask extends AsyncTask<String, Void, JSONObject> {

  ProgressDialog postDialog;

  @Override
  protected void onPreExecute() {
   postDialog = ProgressDialog.show(BLOA.this,
     getText(R.string.tweet_progress_title),
     getText(R.string.tweet_progress_text), true, // indeterminate
                 // duration
     false); // not cancel-able
  }

  @Override
  protected JSONObject doInBackground(String... params) {

   JSONObject jso = null;
   try {
    HttpPost post = new HttpPost(
      "http://twitter.com/statuses/update.json");
    LinkedList<BasicNameValuePair> out = new LinkedList<BasicNameValuePair>();
    out.add(new BasicNameValuePair("status", params[0]));
    post.setEntity(new UrlEncodedFormEntity(out, HTTP.UTF_8));
    post.setParams(getParams());
    // sign the request to authenticate
    mConsumer.sign(post);
    String response = mClient.execute(post,
      new BasicResponseHandler());
    jso = new JSONObject(response);
   } catch (UnsupportedEncodingException e) {
    e.printStackTrace();
   } catch (OAuthMessageSignerException e) {
    e.printStackTrace();
   } catch (OAuthExpectationFailedException e) {
    e.printStackTrace();
   } catch (OAuthCommunicationException e) {
    e.printStackTrace();
   } catch (ClientProtocolException e) {
    e.printStackTrace();
   } catch (IOException e) {
    e.printStackTrace();
   } catch (JSONException e) {
    e.printStackTrace();
   } finally {

   }
   return jso;
  }

  // This is in the UI thread, so we can mess with the UI
  protected void onPostExecute(JSONObject jso) {
   postDialog.dismiss();
   if (jso != null) { // authorization succeeded, the json object
     // contains the user information
    mEditor.setText("");
    mLast.setText(getCurrentTweet(jso));
   } else {
    mLast.setText(getText(R.string.tweet_error));
   }
  }
 }

推荐答案

请描述您使用的是什么 Client/Consumer/Provider，它们必须是 DefaultHttpClient/CommonsHttpOAuthConsumer/CommonsHttpOAuthProvider 肯定能正常工作.

Please describe what Client/Consumer/Provider you are using, they must be DefaultHttpClient/CommonsHttpOAuthConsumer/CommonsHttpOAuthProvider to work properly for sure.

确保在调用此代码之前调用 consumer.setTokenWithSecret(oToken, oTokenSecret);.

Ensure you call consumer.setTokenWithSecret(oToken, oTokenSecret); before calling this code.

此外，post.getParams().setBooleanParameter(CoreProtocolPNames.USE_EXPECT_CONTINUE, false); 是否存在于您的帖子参数中?

Also, is post.getParams().setBooleanParameter(CoreProtocolPNames.USE_EXPECT_CONTINUE, false); exists in your post params?

使用空的 BasicResponseHandler 的原因是什么，我想它什么都不处理，并且可以在 execute 调用中省略.

What's the reason for using empty BasicResponseHandler, it handles nothing and it can be omitted in execute call, I suppose.

而且，可能是一个愚蠢的问题，可能是您在 setEntity(...)

And, may be a dumb question, may be you are overwriting params when calling setParams(...) after setEntity(...)
