是什么让FederatedAuthentication.SessionAuthenticationModule返回NULL？ [英] What makes the FederatedAuthentication.SessionAuthenticationModule return NULL?

问题描述

我不知道为什么，但我FederatedAuthentication.SessionAuthenticationModule被解析为NULL，并撞毁我的应用程序，当我尝试运行我的ClaimsTransformer（）模块：

I'm not sure why but my FederatedAuthentication.SessionAuthenticationModule is resolving as NULL and crashing my app when I try to run my ClaimsTransformer() module:

    public void EstablishSession(ClaimsPrincipal principal)
    {
        var sessionToken = new SessionSecurityToken(principal, TimeSpan.FromHours(8))
        {
            IsPersistent = false, // make persistent
            IsReferenceMode = true // cache on server
        };


        FederatedAuthentication.SessionAuthenticationModule.WriteSessionTokenToCookie(sessionToken);
       // FederatedAuthentication.SessionAuthenticationModule == null and I throw an error :(
    }

下面是什么在我的web.config：

Here's what's in my web.config:

<configSections>
  <section name="system.identityModel" type="System.IdentityModel.Configuration.SystemIdentityModelSection, System.IdentityModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" />
  <section name="system.identityModel.services" type="System.IdentityModel.Services.Configuration.SystemIdentityModelServicesSection, System.IdentityModel.Services, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" />
</configSections>
<system.web>
  <authentication mode="None" />
</system.web>
<system.webServer>
  <modules runAllManagedModulesForAllRequests="true">
    <remove name="RoleManager" />
    <remove name="FormsAuthentication" />
    <remove name="SessionAuthenticationModule" />
    <add name="SessionAuthenticationModule" type="System.IdentityModel.Services.SessionAuthenticationModule, System.IdentityModel.Services, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
  </modules>
</system.webServer>
<system.identityModel>
  <identityConfiguration>
    <claimsAuthenticationManager type="Web.Infrastructure.Authentication.ClaimsTransformer, Web" />
  </identityConfiguration>
</system.identityModel>
<system.identityModel.services>
  <federationConfiguration>
    <cookieHandler requireSsl="false" />
  </federationConfiguration>
</system.identityModel.services>

这是推动我疯了，因为我有一个（概念验证）运行的代码项目没有任何问题，并出现是我需要得到这个功能的工作，但对于一些奇怪的原因，当我尝试在我们实际的项目实施，我FederatedAuthentication.SessionAuthenticationModule始终是NULL。

This is driving me crazy as I have the code running in a (proof of concept) project without any problems, and appears is all I need to get this functionality working, but for some strange reason, when I try to implement in our real project, my FederatedAuthentication.SessionAuthenticationModule is always NULL.

我缺少的是在这里吗？有任何想法吗？为什么不SessionAuthenticationModule正确初始化？

What am I missing here? Any Ideas? Why is the SessionAuthenticationModule not initializing correctly?

推荐答案

我在与已经工作的项目，几乎FederatedAuthentication.WSFederationAuthenticationModule相同的行为。

I'm having almost same behavior with already-working project and FederatedAuthentication.WSFederationAuthenticationModule.

问题解决了从IIS Express设为我切换到完整的IIS（对项目文件不良合并）。

Problem solved my switching from IIS Express to full IIS (bad merge of for project file).

你也可以尝试这个模块添加不仅一节，但是：

Also you can try to add this module not only to a section, but :

<system.web>
<httpModules>
<add name="SessionAuthenticationModule" type="System.IdentityModel.Services.SessionAuthenticationModule, System.IdentityModel.Services, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

您可以参考这个的为样本MSDN文章。
