WCF - 自定义凭据和安全令牌

我对 WCF 开发相当陌生，在学习该框架时遇到了一些问题。我有一个必须支持 REST 和 SOAP 的服务 API。到目前为止，这很容易实现，尤其是使用 WCF4 和路由。

我目前正在研究授权，并通过创建两个新的管理器类来扩展 AuthorizationManager：“ApiKeyAuthorizationManager”和“ApiKeyAndTokenAuthorizationManager”

我的大多数服务都需要 ApiKey 和令牌 (GUIDS)；初始身份验证时，您只需要有效的 ApiKey 和密码即可接收 Token。

到目前为止，REST 工作得很好，因为授权管理器会通过查询字符串来获取 ApiKey 和/或令牌。

例如，服务 uri 如下所示： *http://api.domain.com/Service/Operation/ http://api.domain.com/Service/Operation/{someVariableValue}？ApiKey=GUID&Token=GUID

我现在的问题是授权 SOAP 服务调用。我做了一些研究，并得出了一些结论，我想在实施之前验证其正确性。

为了使用自定义凭据授权 SOAP，我应该：

1. 创建自定义服务令牌（MSDN http://msdn.microsoft.com/en-us/library/ms731872.aspx)
2. 通过创建自定义 SecurityTokenProvider、SecurityTokenAuthenticator 和 SecurityTokenSerializer 来扩展 WCF（MSDN http://msdn.microsoft.com/en-us/library/ms730868.aspx)
3. 通过创建自定义授权策略来扩展 WCF (MSDN http://msdn.microsoft.com/en-us/library/ms751416.aspx)

我是否走在正确的道路上？所有这些步骤都需要适合我的场景吗？似乎只是为了验证由两个 GUID 组成的凭证而进行了如此多的定制。

Thanks!

这是一项非常艰巨的任务。自定义凭证和安全令牌几乎没有记录。事实证明，找到高质量的博客文章本身几乎是不可能的。我一直在努力，很快就找到了可行的解决方案。我什至遇到了与中描述的相同的障碍这个帖子 https://stackoverflow.com/questions/563037/wcf-authentication-with-custom-clientcredentials-what-is-the-clientcredentialtyp.

当我尝试访问我的服务以发现 wsdl 或 mex 时，我收到此错误：

The service encountered an error.

我建议您关注 Windows Identity Foundation，并朝着基于声明的安全/联合的方向发展。该模型更好地支持自定义凭据，因为它们只是一组不同的声明。
