我正在用 Java [GWT] 开发基于 Web 的应用程序
我遇到了 TwitterException 问题。
我使用了有效的凭证。
推特 twitter = new Twitter(myTwitterId, myTwitterPwd);
当我调用 twitter.getFollowers() 方法时

我收到以下错误消息

我想在我的网站中显示我的关注者图片，但在调用此方法 twitter.getFollowers() 方法后抛出异常。所以无法获得我的追随者图片:(

请为我提供简单的解决方案

希望得到您最好的合作

提前致谢!!!

是的，您的身份验证无效，因为 Twitter 最近做了一些更改关于它如何让第 3 方代码进行身份验证。

• http://news.techworld.com/security/3237604/twitter-turns-on-oauth-api-authentication/
• http://www.networkworld.com/news/2010/083110-twitter-api-has-new-third.html?hpg1=bn
• http://www.wired.com/epicenter/2010/08/twitter-login-errors/
• http://groups.google.com/group/twitter-api-announce/browse_thread/thread/f71eb68600996af8

换句话说，API 的基本身份验证已关闭。

正如 Allain 提到的，oAuth 是必经之路。
