Question

在我的方案中，用户无法注册，会有管理员，管理员将使用默认密码创建用户，以后可以更改。

我正在审查复数视频，根据这些视频，我应该将[授权]标签放在动作方法中。

我做了以下操作，但是一旦我这样做了，我就无法在http://localhost/Account/Register上看到任何内容，也无法作为登录用户。

角色管理员已存在。
登录用户还与UserInRoles表中的该角色相关联。

如果我删除[Authorize]属性，那么我可以访问注册页面。

// GET: /Account/Register
    [HttpPost]
    [Authorize(Roles = "admin")]
    public ActionResult Register()
    {
        return View();
    }

    //
    // POST: /Account/Register

    [HttpPost]
    [Authorize(Roles="admin")]
    public ActionResult Register(RegisterModel model)
    {
        if (ModelState.IsValid)
        {
            // Attempt to register the user
            MembershipCreateStatus createStatus;
            Membership.CreateUser(model.UserName, model.Password, model.Email, null, null, true, null, out createStatus);

            if (createStatus == MembershipCreateStatus.Success)
            {
                FormsAuthentication.SetAuthCookie(model.UserName, false /* createPersistentCookie */);
                return RedirectToAction("Index", "Home");
            }
            else
            {
                ModelState.AddModelError("", ErrorCodeToString(createStatus));
            }
        }

        // If we got this far, something failed, redisplay form
        return View(model);
    }

登录部分是：

@if(Request.IsAuthenticated) {
    <text>Welcome <strong>@User.Identity.Name</strong>!
    [ @Html.ActionLink("Register", "Register", "Account") ]
    [ @Html.ActionLink("Log Off", "LogOff", "Account") ]
    [ @Html.ActionLink("Change Password", "ChangePassword", "Account") ]
    [ @Html.ActionLink("Position", "Position", "Position") ]
    [ @Html.ActionLink("User Position", "Position", "UserPositionPosition") ]
    </text>
}
else {
    @:[ @Html.ActionLink("Log On", "LogOn", "Account") ]
}

Answer 1

这个问题是在web.config中默认情况下将rolemanager设置为false而不是true。

很抱歉，很容易解决，但从未想过它会被禁用。！

Answer 2

那应该有用。

我会说你在尝试不同的事情时已经做了别的事。

EG：您确定控制器上没有其他的Authorize属性吗？例如：

[Authorize(Roles="ADifferentRole")]

管理员角色拼写是否正确（例如，确定它不是管理而不是管理员）？

你确定你没有注册，然后没注意到你没有以管理员身份登录，而是以最近创建的用户身份登录（见下文，你的代码中存在各种错误）

抱歉，我无法提供更多帮助，但您所展示的内容应该有效。

错误：

您的注册HttpPost操作中有一个错误，它是您想要的用途。如果您有另一个用户创建登录，那么当该用户成功注册某人时，您的代码将设置身份验证cookie为新用户的身份。

这可能是您遇到问题的原因。执行此操作的代码是：

if (createStatus == MembershipCreateStatus.Success)
            {
                FormsAuthentication.SetAuthCookie(model.UserName, false /* createPersistentCookie */);
                return RedirectToAction("Index", "Home");
            }

您需要用以下内容替换该块：

if (createStatus == MembershipCreateStatus.Success)
            {
                return RedirectToAction("Index", "Home"); // or wherever you want to go...
            }

仅允许在ASP.NET MVC中将用户注册到管理员
