Asp.Net MVC 5 Owin Twitter Auth 抛出 401 异常

我使用 Owin 中间件设置了 OAuth 身份验证，基于使用个人帐户"身份验证启动新 Web 项目时创建的默认项目.

I have set up OAuth authentication using the Owin middleware based off the default project that gets created when starting a new Web project using "Individual accounts" authentication.

我对其进行了一些调整，但 Facebook 和 Google 运行良好，但是，当我单击twitter"按钮发出挑战时，它会抛出 500 http 异常并显示错误消息:

I've tweaked it a bit, but Facebook and Google are working great, however, when I click on the "twitter" button to issue the challenge, it's throwing a 500 http exception with the error message:

响应状态码不表示成功:401(未授权).

Response status code does not indicate success: 401 (Unauthorized).

这只出现在 Twitter 上.这是我的身份验证配置:

This only comes up with Twitter. Here is my auth config:

// Just a configuration section that reads from the web.config
var configuration = new OwinCookieConfigurationSection("owinCookieConfiguration");
app.UseCookieAuthentication(GetCookieAuthenticationOptions(configuration));
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);

app.UseTwitterAuthentication(
    consumerKey: "XXX",
    consumerSecret: "XXX"
);

app.UseFacebookAuthentication(
    appId: "XXX",
    appSecret: "XXX"
);

app.UseGoogleAuthentication();

这绝对是一个 500 错误，而不是它所指示的 401 错误，我已经确认它从未使它通过原始帖子挑战到 Twitter.堆栈跟踪似乎显示 Twitter 没有从获取请求令牌调用返回成功代码:

It's definitely a 500 error, not a 401 error as it indicates and I have confirmed it never makes it passed the original post challenge to Twitter. The stack trace appears to show Twitter is not returning a success code from the ObtainRequestToken call:

有什么想法吗?
