问题描述

大家好，

Hi everyone,

 public ActionResult Login(LoginModel model, string returnUrl)
        {
 if (User.Identity.IsAuthenticated)//this is get always false
            {
string user = User.Identity.Name;//here i need username
            }
  
            if (ModelState.IsValid && WebSecurity.Login(model.UserName, model.Password,     persistCookie: model.RememberMe))
            {
                return RedirectToLocal(returnUrl);
            }

            // If we got this far, something failed, redisplay form
            ModelState.AddModelError("", "The user name or password provided is incorrect.");
            return View(model);
        }

User.Identity.IsAuthenticated always return false so userid comes always -1, I am not even able to short out my mistake, what mistake am doing and how can i overcome with this, please help me.. 

推荐答案

User.Identity.IsAuthenticated在调用FormsAuthentication.SetAuthCookie（）之后，在下一个请求之前不会设置为true。



请参阅http://msdn.microsoft.com/en-us/ library / twk5762b.aspx



SetAuthCookie方法将一个表单身份验证票证添加到cookie集合，或者如果CookiesSupported为false，则添加到URL。表单身份验证票证将表单身份验证信息提供给浏览器发出的下一个请求。

User.Identity.IsAuthenticated won't be set to true until the next request after calling FormsAuthentication.SetAuthCookie().

See http://msdn.microsoft.com/en-us/library/twk5762b.aspx

The SetAuthCookie method adds a forms-authentication ticket to either the cookies collection, or to the URL if CookiesSupported is false. The forms-authentication ticket supplies forms-authentication information to the next request made by the browser.
