java - 线程 "main"com.restfb.exception.FacebookOAuthException : Received Facebook error response of type OAuthException 中出现异常

Question

我正在使用restFB API运行一个简单的代码，在我创建 token 访问后，程序正在运行，从我的Facebook帐户检索数据，但过了一会儿我收到了这条异常消息

Exception in thread "main" com.restfb.exception.FacebookOAuthException: Received Facebook error response of type OAuthException: Error validating access token: Session has expired at unix time 1376380800. The current unix time is 1376392638.

    at com.restfb.DefaultFacebookClient.fetchObject(DefaultFacebookClient.java:244)
    at Example.main(Example.java:19)

我运行的产生上述异常的代码如下:

public static void main(String[] args) {
    FacebookClient facebookClient = new DefaultFacebookClient("Token_Access_Code");

    User user = facebookClient.fetchObject("me", User.class);
    Page page = facebookClient.fetchObject("cocacola", Page.class);

    System.out.println("User name: " + user.getName());
    System.out.println("Page likes: " + page.getLikes());

}

以前有人遇到过这样的异常吗？

您需要重新生成访问 token 。即使根据 FB 文档，访问 token 应该持续 60 天，我也遇到了相同的错误。检查此链接:
