asp.net - GetExternalLoginInfoAsync() loginInfo 返回 null - 但仅在几个小时后

Question

我使用 Strava 作为我的外部登录提供商(我假设这与 Strava 无关，也可能是 google 或 facebook)运行几个小时/天甚至几周后 GetExternalLoginInfoAsync 返回 null。我读过很多其他有同样问题的问题，但没有找到解决方案。我发布了整个ConfigureAuth方法，以防万一我的订单出了问题。

如果您有 Strava 帐户，您可能会遇到此问题:fartslek.no/Account/Login

    public void ConfigureAuth(IAppBuilder app)
    {
        // Configure the db context, user manager and signin manager to use a single instance per request
        app.CreatePerOwinContext(ApplicationDbContext.Create);
        app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
        app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);

        // Enable the application to use a cookie to store information for the signed in user
        // and to use a cookie to temporarily store information about a user logging in with a third party login provider
        // Configure the sign in cookie
        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
            LoginPath = new PathString("/Account/Login"),
            Provider = new CookieAuthenticationProvider
            {
                // Enables the application to validate the security stamp when the user logs in.
                // This is a security feature which is used when you change a password or add an external login to your account.  
                OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
                    validateInterval: TimeSpan.FromMinutes(30),
                    regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
            },
            CookieManager = new SystemWebCookieManager()
        });            
        app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);

        app.UseTwoFactorSignInCookie(DefaultAuthenticationTypes.TwoFactorCookie, TimeSpan.FromMinutes(5));

        app.UseTwoFactorRememberBrowserCookie(DefaultAuthenticationTypes.TwoFactorRememberBrowserCookie);


        app.UseStravaAuthentication( new StravaAuthenticationOptions{
              ClientId="XXX",
              ClientSecret= "FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF",

        });
    }

我正在使用这个https://github.com/Johnny2Shoes/Owin.Security.Strava获取 StravaAuth。

当它停止工作时，天蓝色重置是不够的，但如果我进行新的部署，一切都会工作一段时间。

我正在使用 Owin 3.0.1 和 Mvc 5.2.3

Answer 1

我也遇到了同样的问题。经过一番谷歌搜索后，我发现这是 Owin 中的一个已知错误，因为他们处理 cookie 的方式。

This issue已提交给 Katana Team，但看起来他们根本不会修复它。有很多解决方法，但这是我能找到的最简单的方法:

    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public ActionResult ExternalLogin(string provider, string returnUrl)
    {
        ControllerContext.HttpContext.Session.RemoveAll();

        // Request a redirect to the external login provider
        return new ChallengeResult(provider, Url.Action("ExternalLoginCallback", "Account", new { ReturnUrl = returnUrl }));
    }
