MVC 5 - 角色 - 的isUserInRole和添加用户角色 [英] MVC 5 - Roles - IsUserInRole and Adding user to role

问题描述

在MVC4我曾经Roles.IsUserInRole检查，如果给定用户在一定的作用。然而，随着MVC5我不能这样做了......

In MVC4 i used Roles.IsUserInRole to check if a given user is in some role. However, with MVC5 i can't do it anymore...

首先，它让我在web.config中启用RoleManager但后来我发现，微软搬离Web.Security客场Microsoft.AspNet.Identity。

At first, it asked me to enable RoleManager at the web.config but then i discovered that microsoft moved away from Web.Security to Microsoft.AspNet.Identity.

我现在的问题是，随着Microsoft.AspNet.Identity我该怎么做类似Roles.IsUserInRole的行动？
和/或创建角色和用户之间的关系。

My question now is, with Microsoft.AspNet.Identity how do i do an action similar to Roles.IsUserInRole? And/or create a relation between the Role and the User.

顺便说一句，我仍然试图理解新的身份验证方法（ClaimsIdentity？）。

By the way, i'm still trying to understand the new authentication methods (ClaimsIdentity?).

There's also a complete demo project to get you started: https://github.com/TypecastException/AspNet-Identity-2-With-Integer-Keys

如果你把这个作为你的身份基础的基础，你会像这样结束：

If you take this as the basis for your Identity foundation you'll end up with something like this:

var userManager = HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>();
const string name = "YourUsername"
const string roleName = "Admin";

var user = userManager.FindByName(name);
//check for user roles
var rolesForUser = userManager.GetRoles(user.Id);
//if user is not in role, add him to it
if (!rolesForUser.Contains(role.Name)) 
{
    userManager.AddToRole(user.Id, role.Name);
}
