asp.net-mvc - WebApp-WebAPI-OpenIDConnect-DotNet 未部署在 azure 上

Question

我已经创建了WebApp-WebAPI-OpenIDConnect-DotNet的示例项目。引用项目可在 git 上找到。 .

我按照 git repo 上描述的所有步骤进行操作。我的示例项目在本地主机上正常运行。但是当我在 Azure 上部署项目时，出现以下错误。

请检查下面的堆栈跟踪。

我正在处理一个相同的案例。我的项目正在开发环境上工作，并在将其发布到生产环境后在同一行上获取 NullRefenceException 。经过研究后，我发现 Request.Current 没问题，但 Request.Current.Session 为空。所以，我将代码更改为这样:

public void Load()
    {
        lock (FileLock)
        {
            if (HttpContext.Current != null && HttpContext.Current.Session != null)
            {

                if (HttpContext.Current.Session[CacheId] == null)
                    throw new System.NullReferenceException("CacheId is null");

                Deserialize((byte[]) HttpContext.Current.Session[CacheId]);
            }
        }
    }

之后，它给我 WebExcetpion 400(错误请求)，这是在创建 session 之前发生的。

为了处理这种错误，我更改了 Startup.Auth.cs:

                Notifications = new OpenIdConnectAuthenticationNotifications()
                {
                    AuthenticationFailed = OnAuthenticationFailed,
                    ...
                }

然后:

   private Task OnAuthenticationFailed(AuthenticationFailedNotification<OpenIdConnectMessage, OpenIdConnectAuthenticationOptions> notification)
    {
        UtilLogger.PublishException(notification.Exception);

        notification.HandleResponse();
        notification.Response.Redirect($"{postLogoutRedirectUri}?message={notification.Exception.Message}");
        return Task.FromResult(0);
    }
