如何引用HttpContext.Current。用户在MVC中的Application_PostAuthenticateRequest之后?

So here's a break down of my issue in steps:

下面是我的问题的分解步骤:

1. The user logs in with Google.
2. 用户使用谷歌登录。
3. On the login callback, information about the user is gathered
4. 在登录回调中，将收集关于用户的信息
5. Roles are assigned based on the user
6. 角色是根据用户分配的
7. A FormsAuthenticationTicket is created which passes the user/roles to the Application_PostAuthenticateRequest in Global.asax
8. 创建一个FormsAuthenticationTicket，它将用户/角色传递给Global.asax中的Application_PostAuthenticateRequest
9. In that request a GenericPrinciple is created from the authentication ticket and roles
10. 在该请求中，从身份验证票据和角色创建一个通用原则
11. HttpContext.Current.User is set to the above variable
12. HttpContext.Current。User设置为上述变量

Now my question is, now that I set who the current user is that is using the website, how can I reference them? After the post authenticate complete, I check the current user and it's null. Should I be setting the principle to a different variable other than HttpContext.Current.User?

现在我的问题是，既然我设置了使用网站的当前用户是谁，我如何引用他们?完成post验证后，我检查当前用户，它为null。我应该将原则设置为HttpContext.Current.User之外的其他变量吗?

Callback

回调

public async Task<ActionResult> ExternalLoginCallback(string returnUrl)
{
...
// Get roles for current user
string roles = "bob,adminbob,cthulu";

FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(
   1,
   loginInfo.Email,
   DateTime.Now,
   DateTime.Now.AddMinutes(30), // value of time out property
   false,
   roles,
   FormsAuthentication.FormsCookiePath);

HttpCookie authCookie = new HttpCookie(FormsAuthentication.FormsCookieName, FormsAuthentication.Encrypt(ticket));
Response.Cookies.Add(authCookie);
...
}

Post Authenticate in Global.asax

后验证Global.asax

protected void Application_PostAuthenticateRequest(Object sender, EventArgs e) {
    HttpCookie authCookie = Context.Request.Cookies[FormsAuthentication.FormsCookieName];

   if (authCookie != null) {
      FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);
      string[] userRoles = authTicket.UserData.Split(new Char[] { ',' });
      GenericPrincipal userPrincipal = new GenericPrincipal(new GenericIdentity(authTicket.Name), userRoles);
      HttpContext.Current.User = userPrincipal; //How do I reference this in the program?
   }
}

Nevermind I figured out why it was returning blank. When I was calling the method to check the Name, the Identity wasn't authenticated yet. If you try to get the name without it being authenticated, it returns blank.

没关系，我弄明白了为什么它是空白的。当我调用这个方法来检查名称时，身份还没有被验证。如果您试图在未经身份验证的情况下获取该名称，它将返回空。

So I just simply checked with:

所以我只是检查一下

HttpContext.Current.User.Identity.IsAuthenticated
