为什么Request.IsAuthenticated在MVC 4中始终返回False? [英] Why Request.IsAuthenticated return False always in MVC 4 ?

问题描述

第一次运行时，我的代码运行良好，但是第二次运行时，我的登录页面再次重定向到登录页面，但是无法重定向到主页.我跟踪此代码，并且在跟踪中我知道它(Request.IsAuthenticated)返回false.

这是我的模型代码:

In first run my code work good but for second run my login page redirect to login page again but that can not redirect to home page .I trace this code and in trace i knowed that it (Request.IsAuthenticated) return false .

This is my models code :

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Data.Entity;
using Portal.Models;
using System.Linq;
using System.Web.Http;

namespace Portal.Models

        [RegularExpression(".+@.+\\..+", ErrorMessage = "Please Enter Correct Email Address")]
        [Display(Name = "User name")]
        public string Username { get; set; }

        [Required(ErrorMessage = "Please Enter Password")]
        [StringLength(int.MaxValue, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
        [DataType(DataType.Password)]
        [Display(Name = "Password")]
        public string Password { get; set; }

        [Required(ErrorMessage = "Please Enter Confirm Password")]
        [DataType(DataType.Password)]

        [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
        public string ConfirmPassword { get; set; }

                    return false;
                }
            }
        }
    }

    public partial class WebSite_UserDB

        public string NationalCode { get; set; }
        public Nullable<int> CityID { get; set; }
    }
}

这是我的布局:

This is my layout :

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width" />
    <title>@ViewBag.Title</title>
    @Styles.Render("~/Content/css")
    @Scripts.Render("~/bundles/modernizr")
</head>
<body>
    <div style="width: auto; background-color: #728ea7;">
        @if (Request.IsAuthenticated) {
            @Html.Encode(User.Identity.Name)
            @Html.ActionLink("Sign Out", "Logout", "User")
        }
        else {
            @Html.ActionLink("Register", "Register", "User")
            <span> | </span>
            @Html.ActionLink("Sign In", "Login", "User")
        }
    </div>
 
    @RenderBody()
 
    @Scripts.Render("~/bundles/jquery")
    @RenderSection("scripts", required: false)
</body>
</html>

This is my Login:
@model Portal.Models.LoginWebSite_UserDB

@{
    ViewBag.Title = "Login";
    Layout = "~/Views/Shared/_Layout.cshtml";
}
@using (Html.BeginForm())
{
    @Html.ValidationSummary(true, "Login failed. Check your login details.");
    <div>
        <fieldset>
            <legend>Login</legend>
            <div class="editor-label">
                User name
            </div>
            <div class="editor-field">
                @Html.TextBoxFor(u => u.Username)
                @Html.ValidationMessageFor(u => u.Username)
            </div>
            <div class="editor-label">
                Password
            </div>
            <div class="editor-field">
                @Html.PasswordFor(u => u.Password)
                @Html.ValidationMessageFor(u => u.Password)
            </div>
            <input type="submit" value="Log In" />
        </fieldset>
    </div>
}

这是我的控制器:

This is my controller :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Security;
using Portal.Models;

namespace Portal.Controllers
{
    public class UserController : Controller
    {

        //
        // GET: /User/

        public ActionResult Index()
        {
            return View();
        }
        [HttpGet]
        public ActionResult Login()
        {
            return View();
        }

        [HttpPost]
        public ActionResult Login(Models.LoginWebSite_UserDB user)
        {
            
            if (ModelState.IsValid)
            {
                if (user.IsValid(user.Username, user.Password))
                {
                    return RedirectToAction("Index", "Home");
                }
                else
                {
                    ModelState.AddModelError("", "Login data is incorrect!");
                }
            }
            return View();
        }
        public ActionResult Logout()
        {
            FormsAuthentication.SignOut();
            return RedirectToAction("Index", "Home");
        }
        

        [HttpGet]
        public ActionResult Register()
        {
            return View();
        }
        
        [HttpPost]
        public ActionResult Register(Models.ViewUserDB mRegister)
        {
            Models.ViewUserDB wu = new Models.ViewUserDB();
            if (mRegister.ConfirmPassword != mRegister.Password)
            {
                TempData["UnSuccess"] = "Your register unsuccess";
                return View();
            }
            if (wu.AddRegister(mRegister.Username, mRegister.Firstname, mRegister.Lastname, mRegister.Password))
            {
                    ViewData["Success"] = "Your register success";
                    return View();
            }
            else
            {
                    TempData["UnSuccess"] = "This user name is exist";
                    return View();
            }
        }

    }
}

推荐答案

，您应该缺少身份验证Cookie设置程序

Thought you have missing the authentication cookie setter

System.Web.Security.FormsAuthentication.SetAuthCookie(user.Username, false);

在

if (user.IsValid(user.Username, user.Password))

之后.
但是应该在USER内部创建身份，并将身份验证类型设置为不保留为空的某个值.

This is a very late response.
But the identity inside the USER should be created with the authenticationtype set to some value not left empty.

这是一个很晚的响应.但我建议使用此链接:

This is a very late response. But I would recommend this link:
