openid - 如何在 DotNetOpenAuth 上添加我的声明

Question

如何使用 DotNetOpenAuth 作为 OpenID 提供程序将我自己的声明添加到用户断言中？

我需要向 ClaimsRequest 和 ClaimsResponse 添加一些属性，例如“UserID”。我在类 ClaimsRequest.cs 和 ClaimsResponse.cs 中都添加了这个属性，当我用这个更改构建 DotNetOpenAuth 时，它在 VS 2010 中运行良好，但是当我在 iis 7.5 上发布时它抛出这个异常:

Server Error in '/OpenID' Application.

Could not load file or assembly 'DotNetOpenAuth.Contracts' or one of its dependencies. Strong name signature could not be verified. The assembly may have been tampered with, or it was delay signed but not fully signed with the correct private key.

WRN: Assembly binding logging is turned OFF. To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging. To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

您不应该向 ClaimsRequest 添加属性或 ClaimsResponse类，因为它是简单注册扩展，并且有一组固定的属性。

相反，您应该使用属性交换扩展，它允许您在不重新编译库的情况下设置和检索其上的任意属性(声明)。在 DotNetOpenAuth 中，这意味着使用 FetchRequest和 FetchResponse类来承载您的自定义声明。

您从 IIS 收到的错误是因为您对 DotNetOpenAuth 的构建进行了不正确的“签名”。但是，如果您按照这些说明进行操作，则不需要自己构建它，因此我将放弃有关如何正确构建的说明。
