我正在开发一个asp.net mvc 3.0应用程序,它具有简单的身份验证过程.用户填写一个表单,该表单通过ajax调用发送到服务器并获得响应,但这里的问题是使用以下方法:
FormsAuthentication.SetAuthCookie(person.LoginName,false);
是不足以填充’HttpContext.Current.User’,它需要运行以下方法:
FormsAuthentication.RedirectFromLoginPage("...");
问题在于,正如我所提到的,loggin表单使用ajax表单,并使用json获取响应,因此无法重定向.
我怎么能填写’HttpContext.Current.User’?
谢谢.
更新:
这是注册方法:
[HttpPost]
public ActionResult Register(Person person)
{
var q = da.Persons.Where(x => x.LoginName == person.LoginName.ToLower()).FirstOrDefault();
if (q != null)
{
ModelState.AddModelError("","Username is repettive,try other one");
return Json(new object[] { false,this.RenderPartialViewToString("RegisterControl",person) });
}
else
{
if (person.LoginName.ToLower() == "admin")
{
person.IsAdmin = true;
person.IsActive = true;
}
da.Persons.Add(person);
da.SaveChanges();
FormsAuthentication.SetAuthCookie(person.LoginName,false);
return Json(new object[] { true,"You have registered successfully!" });
}
}
这是我最终使用的版本,它基于@ AdamTuliper-MSFT的答案.它只能在登录后立即使用,但在重定向之前,允许其他代码访问HttpContext.User.

在调用SetAuthCookie()后调用此方法,如下所示:
// in login function
FormsAuthentication.SetAuthCookie(model.UserName,model.RememberMe);
AuthenticateThisRequest();
private void AuthenticateThisRequest()
{
//NOTE: if the user is already logged in (e.g. under a different user account)
// then this will NOT reset the identity information. Be aware of this if
// you allow already-logged in users to "re-login" as different accounts
// without first logging out.
if (HttpContext.User.Identity.IsAuthenticated) return;
var name = FormsAuthentication.FormsCookieName;
var cookie = Response.Cookies[name];
if (cookie != null)
{
var ticket = FormsAuthentication.Decrypt(cookie.Value);
if (ticket != null && !ticket.Expired)
{
string[] roles = (ticket.UserData as string ?? "").Split(',');
HttpContext.User = new GenericPrincipal(new FormsIdentity(ticket),roles);
}
}
}
编辑:删除对Request.Cookies的调用,如@ AdamTuplier-MSFT所述.
