Question

我有一些实施最新PHP SDK和OAuth2的大错误，因此我将其分解为使用提供的示例来演示我遇到的问题。

我正在使用此代码。我收到OAuthException＆＃39;必须使用活动访问令牌来查询有关当前用户的信息。＆＃39;当我点击登录Facebook链接时，我继续收到此错误，我没有连接。请注意，这通常在所有cookie和会话都已清除时起作用，但是如果我返回它几个小时后就不再有效了。

我很感激有任何帮助。

另请注意，这不在画布页面上。

Answer 1

Facebook已经提出并接受了最新SDK的错误。我建议从2011年早些时候降级到一个。它解决了我的问题。

Answer 2

好像你很亲密。在facebook的php配置下面，我提供了一个if GET查询来检测用户是否已注销。当他们注销时，条件中的代码会触发

unset($_COOKIE['fbsr_' . $config['appId']]);

而不是

unset($_COOKIE['fbsr_' . $this->getAppId()]);

这似乎是一种魅力。
