FederatedAuthentication.WSFederationAuthenticationModule在运行时为null

Question

我试图在Application_Start()中订阅RedirectingToIdentityProvider事件,但是FederatedAuthentication.WSFederationAuthenticationModule为null

码

protected void Application_Start()
{
 FederatedAuthentication.WSFederationAuthenticationModule.RedirectingToIdentityProvider += WSFederationAuthenticationModule_RedirectingToIdentityProvider;
}

Answer 1

尝试这样做 - 适合我.

void Application_Start()
{
    FederatedAuthentication.ServiceConfigurationCreated += OnServiceConfigurationCreated;
}


void OnServiceConfigurationCreated(object sender, ServiceConfigurationCreatedEventArgs e)
{
    FederatedAuthentication.WSFederationAuthenticationModule.RedirectingToIdentityProvider += WSFederationAuthenticationModule_RedirectingToIdentityProvider;
} 

Answer 2

听起来您WSFederationAuthenticationModule的配置中可能缺少 。确保你有这个system.webServer\modules：

<add name="WSFederationAuthenticationModule" type="Microsoft.IdentityModel.Web.WSFederationAuthenticationModule, Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" preCondition="managedHandler" />

这在system.web\httpModules：

<add name="WSFederationAuthenticationModule" type="Microsoft.IdentityModel.Web.WSFederationAuthenticationModule, Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
