我正在关注此博文http://prasadtissera.blogspot.com/2014/04/login-with-facebook-for-wso2-identity.html以使用Facebook联合身份验证执行SAML SSO。一切正常，直到Facebook在身份验证后将请求重定向回webapp。在那一点上，控制台提供以下异常，

答案 0 :(得分：1)

WSO2Identity Server 5.0.0中的Facebook身份验证器旨在与Graph API 1.0一起使用，但目前Facebook支持v2.0，这就是为什么可能发生这个问题的原因。因此，您可以编写新的Facebook身份验证器并插入Identity Server。请查看org.wso2.carbon.identity.application.authenticator.facebook以获取实现细节。
