基于角色的ASP.NET MVC登录和重定向 [英] ASP.NET MVC Login and Redirect Based On Role

问题描述

我正在使用ASP.NET MVC生成的默认Login方法，并希望对其进行更改，以便它将根据用户角色重定向到指定的View.我已经检查过该用户是否在该角色中.我在SignInStatus成功块内进行了重定向，但未成功.

I am using the default Login method generated by ASP.NET MVC and wanted to change it so that it will redirect to a specified View based on the user's role. I have checked that the user is in that role. I made the redirect inside the SignInStatus success block with no success.

我在其他代码块中使用 User.IsInRole()，并且工作正常.我认为执行if语句时用户尚未完全登录.我认为是这种情况，但是我不确定我可以实施哪些解决方案.

I use the User.IsInRole() in other blocks of code and works fine. I think the user is not fully logged in when the if statements are executed. I think this is the case, but I am not sure what work around I can implement.

这是我的下面的代码.

// POST: /Account/Login
[HttpPost]
[AllowAnonymous]
[ValidateCustomAntiForgeryTokenAttribute]
public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
{
    if (!ModelState.IsValid)
    {
        return View(model);
    }

    // This doesn't count login failures towards account lockout
    // To enable password failures to trigger account lockout, change to shouldLockout: true
    var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false);
    switch (result)
    {
        case SignInStatus.Success:
            if (User.IsInRole("Customer"))
            {
                return RedirectToAction("Customer", "Home");
            }
            else if (User.IsInRole("Requestor"))
            {
                return RedirectToAction("Caterer", "Home");
            }
            else if (User.IsInRole("Admin"))
            {
                return RedirectToAction("Admin", "Home");
            }
            else
            {
                return RedirectToLocal(returnUrl);
            }
        case SignInStatus.LockedOut:
            return View("Lockout");
        case SignInStatus.RequiresVerification:
            return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe });
        case SignInStatus.Failure:
        default:
            ModelState.AddModelError("", "Invalid login attempt.");
            return View(model);
    }
}

推荐答案

感谢@ stephen.vakil的链接，我通过更改SignInStatus.Success案例中的代码块使它能够正常工作.

Thanks to @stephen.vakil's link I managed to get it to work by changing the block of code inside the SignInStatus.Success case.

            case SignInStatus.Success:
                var user = await UserManager.FindAsync(model.Email, model.Password);
                var roles = await UserManager.GetRolesAsync(user.Id);

                if (roles.Contains("Customer"))
                {
                    return RedirectToAction("Customer", "Home");
                }
                else if (roles.Contains("Requestor"))
                {
                    return RedirectToAction("Caterer", "Home");
                }
                else if (roles.Contains("Admin"))
                {
                    return RedirectToAction("Admin", "Home");
                }
                else
                {
                    return RedirectToLocal(returnUrl);
                }
                ......
