当加入会话cookie来ServiceStack nullreference例外 [英] nullreference exception when adding session cookie to ServiceStack

问题描述

这个问题依赖于相当多的问题/答案在这里：

This question relies quite a bit on the question/answer here:

<一个href=\"http://stackoverflow.com/questions/19160839/reconnecting-to-servicestack-session-in-an-asp-net-mvc4-application\">Reconnecting在一个asp.net应用MVC4 Servicestack会议

Reconnecting to Servicestack session in an asp.net MVC4 application

基本上，我有一个使用ServiceStack进行身份验证一个asp.net MVC应用程序。所建议在上述我加入会话cookie到响应，然后将它添加到jsonserviceclient饼干容器后述的问题。

Basically, I have an asp.net MVC application that is using ServiceStack for authentication. As suggested in the question mentioned above I am adding a session cookie to the response and then adding it to the jsonserviceclient cookie container later.

使用这个code在登录屏幕的用户进行身份验证：

Using this code to authenticate the user at the login screen:

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult login(UserModel user)
    {
        try
        {
            var AuthResponse = client.Post(new Auth
            {
                provider = "credentials",
                UserName = user.user_id,
                Password = user.password,
                RememberMe = true
            });

            if (AuthResponse.SessionId != null)
            {
                FormsAuthentication.SetAuthCookie(AuthResponse.UserName, true);
                var response = System.Web.HttpContext.Current.Response.ToResponse();
                response.Cookies.AddSessionCookie(
                    SessionFeature.PermanentSessionId, AuthResponse.SessionId); 

                return Redirect("/Default");
            }
        }
        catch (Exception ex)
        {
            FormsAuthentication.SignOut(); 
            return Redirect("/");
        }
        return View();
    }

不过，我正从线空裁判异常：

However, I am getting a null ref exception from the line:

response.Cookies.AddSessionCookie(SessionFeature.PermanentSessionId, AuthResponse.SessionId);

堆栈跟踪如下：

at ServiceStack.ServiceHost.Cookies.ToHttpCookie(Cookie cookie)
at ServiceStack.ServiceHost.Cookies.AddCookie(Cookie cookie)
at ServiceStack.ServiceHost.Cookies.AddSessionCookie(String cookieName, String cookieValue, Nullable`1 secureOnly)
at FmStoreScreenMvc3.Controllers.AuthController.login(UserModel user) in <project> 51

我想知道如果有什么似乎明显不对的配置。

I'm wondering if anything seems obviously wrong with this configuration.

更新/注意
我已经改变了违规线（凡nullref被抛出）为：

Update/note I have changed the offending line (Where the nullref is thrown) to:

response.Cookies.AddSessionCookie("foo", "bar", false); 

我仍然得到同样的错误。刚刚打猎什么为空，为什么

I still get the same error. Just hunting for what is null and why

推荐答案

而不是：

response.Cookies.AddSessionCookie(
  SessionFeature.PermanentSessionId, AuthResponse.SessionId);

尝试：

response.SetCookie(SessionFeature.PermanentSessionId, 
    AuthResponse.SessionId, TimeSpan.FromDays(14)));
