我正试图在我的Windows XP机器上使用 Spring Integration with Twitter 和一个独立程序向我的Twitter帐户发布消息。但我收到以下错误 - 

WARNING: POST request for "https://api.twitter.com/1/statuses/update.json" resulted in 401 (Unauthorized); invoking error handler

这是我的代码 -

仅供参考 - 我用twitter4j测试了我的推特令牌和密钥，似乎成功将消息发布到推特上。

这是我的twitter4j代码 -

OAuthSetup.java 

package com.skilledmonster.spring.integration.twitter;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.Calendar;

import twitter4j.Status;
import twitter4j.Twitter;
import twitter4j.TwitterException;
import twitter4j.TwitterFactory;
import twitter4j.auth.AccessToken;
import twitter4j.auth.RequestToken;
public class OAuthSetup {
  /**
   * @param args
   */
  public static void main(String args[]) throws Exception {
      // The factory instance is re-useable and thread safe.
      Twitter twitter = new TwitterFactory().getInstance();

//insert the appropriate consumer key and consumer secret here

      twitter.setOAuthConsumer("onj5cG1P9pe7n9qA8UI4EA", 
          "2l7hqMafKYaTkVBW3YfuBfGdzCtmICOJwjOOCEeQ");
      RequestToken requestToken = twitter.getOAuthRequestToken();
      AccessToken accessToken = null;
      BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
      while (null == accessToken) {
        System.out.println("Open the following URL and grant access to your account:");
        System.out.println(requestToken.getAuthorizationURL());
        System.out.print("Enter the PIN(if aviailable) or just hit enter.[PIN]:");
        String pin = br.readLine();
        try{
           if(pin.length() > 0){
             accessToken = twitter.getOAuthAccessToken(requestToken, pin);
           }else{
             accessToken = twitter.getOAuthAccessToken();
           }
        } catch (TwitterException te) {
          if(401 == te.getStatusCode()){
            System.out.println("Unable to get the access token.");
          }else{
            te.printStackTrace();
          }
        }
      }
      //persist to the accessToken for future reference.
      System.out.println(twitter.verifyCredentials().getId());
      System.out.println("token : " + accessToken.getToken());
      System.out.println("tokenSecret : " + accessToken.getTokenSecret());
      //storeAccessToken(twitter.verifyCredentials().getId() , accessToken);
      Status status = twitter.updateStatus("Testing new Twitter samples for springintegration # "+Calendar.getInstance().getTimeInMillis());
      System.out.println("Successfully updated the status to [" + status.getText() + "].");
      System.exit(0);
    }
}

有谁能告诉我这里出了什么问题？

2 个答案:

答案 0 :(得分：0)

您用于访问Twitter的令牌已被撤销，或者可能对您正在使用的使用者ID /应用程序ID无效。

org.springframework.social.RevokedAuthorizationException: The authorization has been revoked

您需要执行新的授权以获取与您的应用程序一起使用的令牌和机密，或者，您可以在Twitter应用程序配置页面（https://dev.twitter.com/apps/）上生成专门用于个人用途的令牌。这对于方便地测试应用程序非常有用，而无需执行OAuth。

答案 1 :(得分：0)

我认为问题在于属性文件中键值的空格： - ）

我的博客上有full example。
