Question

我使用该身份为用户分配角色。现在我想根据用户的角色将用户重定向到某些页面。例如，具有角色的用户＆＃34; user＆＃34;登录后重定向到一个页面说＆＃34;你好用户＆＃34;。不同于管理员等等。我已经创建了每个页面并验证了授权。但是我应该在登录后重定向到哪里？

您只需更改登录发布操作即可检查用户并重定向到正确的视图。

为普通用户创建单独的视图。

NormalUser.cshtml

@{
    ViewBag.Title = "Normal User";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Hello User!</h2>

控制器内部

[Authorize(Roles = "user")]
    public ActionResult NormalUser()
    {
        ViewBag.Message = "Hello normal user.";

        return View();
    }

然后登录发布操作

// POST: /Account/Login
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    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:
                var user = await UserManager.FindByEmailAsync(model.Email);
                var userRole = await UserManager.GetRolesAsync(user.Id);

                if (userRole.Any(role => role == "user"))
                {
                    RedirectToAction("NormalUser", "Home");
                }
                else
                {
                    RedirectToAction("Index", "Home");
                }

                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);
        }
    }
