在MVC5中使用OAuth时，无限循环返回到身份验证页面 [英] infinite loop going back to authentication page when using OAuth in MVC5

问题描述

我编写了一个使用MVC5和OAuth来利用Google/Facebook身份验证的网页.

I have written a webpage that takes advantage of Google/Facebook auth using MVC5 and OAuth.

有时候，我可以使用Facebook或Google进行很好的身份验证.效果很好.

Sometimes, I'm able to auth very well using either Facebook or Google. It works quite well.

然而，经常发生的是:

1. 导航到登录页面.
2. 选择Google或Facebook.
3. 提供帐户信息，以获取必要的重定向.
4. 重定向回登录页面，但未登录.

我没有收到(或没有在正确的位置查看)任何提示我的错误-我在Azure上使用SSL进行托管.

I'm not receiving (or not looking in the right place) any errors that clue me in - I am using SSL on Azure for hosting.

有人有提示为什么有时起作用，有时却不起作用的提示吗?感觉好像是cookie的事，还是服务器端的配置问题?我不知道为什么它有时会起作用，有时会不起作用.

Does anyone have tips for why it sometimes works, and sometimes does not? This feels like it could be a cookie thing, or maybe a server side configuration problem? I can't figure out why it would sometimes work and sometimes wouldn't work.

我尝试过:

• 使用另一台从未登录过的计算机( 出Cookie)，同样的问题.
• 清除我的cookie缓存，同样的问题.

• Using a second machine, one that has never logged in before (to rule out cookies), same problem.
• Clearing my cookie cache, same problem.

我的配置方式:

public void ConfigureAuth(IAppBuilder app)
{
    // Enable the application to use a cookie to store information for the signed in user
    app.UseCookieAuthentication(new CookieAuthenticationOptions
    {
        AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
        LoginPath = new PathString("/Account/Login")
    });
    // Use a cookie to temporarily store information about a user logging in with a third party login provider
    app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);

    // Uncomment the following lines to enable logging in with third party login providers
    //app.UseMicrosoftAccountAuthentication(
    //    clientId: "",
    //    clientSecret: "");

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

    app.UseFacebookAuthentication(
       appId: "abc",
       appSecret: "123");

    app.UseGoogleAuthentication();
}

我已经按照本教程在MVC5中使用OAuth:

I've followed this tutorial to use OAuth in MVC5: Create an ASP.NET MVC 5 App with Facebook, Twitter, LinkedIn and Google OAuth2 Sign-on (C#)

推荐答案

这是一个主要问题，您的应用程序将随机地开始进入无限循环，有时重新部署该应用程序使其可以工作，但只能是临时的.我发现解决此问题的快速方法是使用@cooper注释的nuget软件包kentor.owincookiesaver.您应该在owin启动类中的cookieauthentication调用之前调用此类，如下所示

this is a major issue where randomly your application will start going into an infinite loop and some times redeploying the application makes it work but only temporary. the quick way i found to address this issue is using nuget package kentor.owincookiesaver as commented by @cooper. you should make a call to this class before cookieauthentication call in the owin startup class as shown below

app.UseKentorOwinCookieSaver();

app.UseCookieAuthentication(new CookieAuthenticationOptions());

很明显，owin和katana中存在一个错误，您的cookie刚刚消失并且可以解决此问题.

Apparently there is a bug in owin and katana where your cookie just disappear and this fixes it.
