问题描述

每当我将以下行添加到Startup类中时，都会出现以下异常.这是一个从mono(Ubuntu)运行的自托管exe.在Windows中工作正常.我将其范围缩小到UseCookieAuthentication调用.我可以实例化这些选项，而不会出现任何问题.知道这里发生了什么吗?我可以使用aspnet Identity和EF6/MySql.

When ever I add the line below to my Startup class I get the exception below. This is a self hosted exe running from mono (Ubuntu). It works fine in windows. I've narrowed it down the UseCookieAuthentication call. I can instantiate the options without any issue. Any idea what is going on here? I have aspnet Identity working and EF6/MySql.

app.UseCookieAuthentication(new CookieAuthenticationOptions());

推荐答案

发生这种情况的原因是，OWIN默认使用DpapiDataProtector，而DPAPI是Windows API(数据保护API)，因此不能单声道运行.幸运的是，您可以在Cookie选项中覆盖默认值.下面是一个示例，其中AesDataProtectorProvider是我在此处找到的自定义IDataProtector:在多个应用程序中使用Oauth票证服务?

Okay this is happening because OWIN uses DpapiDataProtector by default and DPAPI is a windows API (Data Protection API) and does not work in mono. Luckily you can override the default in your cookie options. Below is an example where AesDataProtectorProvider is a custom IDataProtector that I found here: Using Oauth tickets across several services?

        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            TicketDataFormat =
                new SecureDataFormat<AuthenticationTicket>(DataSerializers.Ticket,
                    new AesDataProtectorProvider("testing"), TextEncodings.Base64)
        });

使用此代码，我的项目再次从Mono开始.

With this code my project starts in Mono again.

更新:

您还可以拥有一个自定义IDataProtectionProvider，并让所有owin都使用它:

You can also have a custom IDataProtectionProvider and have all of owin use that with this:

app.SetDataProtectionProvider(new CustomIDataProtectionProvider());
