Question

我正在努力实现自定义FormsAuthenticationProvider，并且我遇到了中间件转换错误。

No conversion available between System.Func`2[System.Collections.Generic.IDictionary`2
[System.String,System.Object],System.Threading.Tasks.Task] and Microsoft.Owin.OwinMiddleware
Parameter name: signature

我的筹码包括

Owin
卡塔纳
南西

我的具体问题是关于在哪里寻找有关如何实施自定义FormsAuthenticationProvider的示例的任何建议？除非有人能发现我的问题。

我的实现如下：

Startup.cs

app.UseFormsAuthentication(new FormsAuthenticationOptions
            {
                LoginPath = "/login",
                LogoutPath = "/logout",
                CookieHttpOnly = true,
                AuthenticationType = Constants.ChainLinkAuthType,
                CookieName = "chainlink.id",
                ExpireTimeSpan = TimeSpan.FromDays(30),
                Provider = kernel.Get<IFormsAuthenticationProvider>()
            });

如果我删除app.UseFormsAuthentication(...)应用程序运行没有错误。

您是否可以尝试将Microsoft.Owin.Host.SystemWeb软件包的版本更新到最新的RC并尝试？你在rc中拥有所有其他Owin * dll但是这是1.0.0。可能导致问题。另请使用Microsoft.Owin.Security.Cookies而不是Microsoft.Owin.Security.Forms。 Forms包现已重命名为Cookies。

使用Owin，Katana和Nancy实现自定义FormsAuthenticationProvider
