授权角色不工作

这是我在控制器中的Sign Up和Login操作方法:
public ActionResult SignUp()
{
return View();
}
[HttpPost]
public ActionResult SignUp(User _user)
{
_user.Authorize = CustomRoles.RegisteredUser;
int lastuserid = entities.Users.Last().UserID;
_user.UserID = lastuserid + 1;
if (ModelState.IsValid)
{
Roles.AddUserToRole(_user.UserName, CustomRoles.RegisteredUser);
entities.Users.Add(_user);
entities.SaveChanges();
RedirectToAction("Index");
}
return View(_user);
}
public ActionResult Login()
{
LoginViewModel LVM = new LoginViewModel();
HttpCookie existingCookie = Request.Cookies["UserName"];
if (existingCookie != null)
{
LVM.UserName = existingCookie.Value;
}
return View(LVM);
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Login(LoginViewModel u)
{
if (ModelState.IsValid)
{
if (u.RememberMe==true)
{
HttpCookie existingCookie = Request.Cookies["UserName"];
if (existingCookie != null)
{
existingCookie.Value = u.UserName;
existingCookie.Expires = DateTime.Now.AddHours(-20);
}
HttpCookie newCookie = new HttpCookie("UserName", u.UserName);
newCookie.Expires = DateTime.Today.AddMonths(12);
Response.Cookies.Add(newCookie);
}
var v = entities.Users.Where(a => a.UserName.Equals(u.UserName) && a.Password.Equals(u.Password)).FirstOrDefault();
if (v != null)
{
System.Web.HttpContext.Current.Session["UserName"] = u.UserName;
return RedirectToAction("Index");
}
}
return View(u);
}
这里是它们应该去的动作方法的示例,其中一些在不同的控制器中但它们的结果是相同的:
[Authorize(Roles = CustomRoles.RegisteredUser)]
public ActionResult Orders(User U)
{
return View();
}
[Authorize(Roles = CustomRoles.Manager)]
public ActionResult Stock()
{
return View(entities.Cars.ToList());
}
发生的是我被重定向回Login方法,这是应该发生的如果用户没有登录,但用户登录了,它仍然发生
您正在尝试实现表单授权,但我认为您忘记了使用HttpContext.User.IsInRole方法来检测用户是否可以访问操作的授权属性。要解决这个问题,您可以通过web配置表单授权。或者你手动分配你的HttpContext。用户通过HttpModule或在Global.asax.cs中使用应用程序事件,例如:
protected void Application_PostAuthenticateRequest(Object sender, EventArgs e)
{
HttpContext context = ((HttpApplication)sender).Context;
HttpCookie existingCookie = Request.Cookies["UserName"];
if (existingCookie != null) {
context = new new GenericPrincipal(new GenericIdentity(existingCookie.Value), new string[]{"Admin", "Manager"});
}
}
