Question

我正在使用SAML 2.0断言发送请求的服务运行集成测试：ReadAssertion(XmlReader reader) System.IdentityModel.Tokens.Saml2SecurityTokenHandler方法正在抛出Element is an invalid XmlNodeType消息的异常。

试图对此进行调查我发现这种情况正在发生，因为该方法期望在签名位置读取结束元素，如果我删除此节点，此方法工作正常，但我得到另一个异常ID4152: The Saml2SecurityToken cannot be validated because the IssuerToken property is not set. Unsigned SAML2:Assertions cannot be validated.

任何人都可以帮我解决问题所在吗？或者是正确格式的请求签名。从我的测试应用程序开始，签名始终是第一位的，我没有这个问题。这是他们寄给我的。

Answer 1

断言的XML中节点的顺序是错误的，并且不符合SAML2。浏览一下saml2-core，特别注意第5节。

Answer 2

感谢您的回答Andy K.我联系了客户，他们确认他们发送的SAML订单错误。

签名出现在AttributeStatement（.Net 4.5）旁边时出现SAML 2.0错误
