Question

我正在创建一个MVC网站，其中应该有两种类型的用户。出于简单目的，用户是（用户，销售）。这是一个名为Steve的用户应该能够作为User或Sales作为单独的帐户存在。我如何使用asp.net身份进行建模，因为它只允许1个用户配置文件和注册/登录流程？我需要2个独立的网站吗？

我已经阅读了我想要做的是创建一个多租户应用程序，但我还没有看到asp.net mvc的任何一个很好的例子。理想情况下，我希望用户转到www.foo.com并消费＆＃34; stuff＆＃34;销售用户在www.foo.com/Sales上创建。用户将在www.foo.com注册并拥有自己的流程，用户将在www.foo.com/Sales注册并拥有自己的产品创建流程。

首先使用EF代码和ASP.net标识对此进行建模的最佳方法是什么？

我的想法：

2个单独的网站 - 但是我可以通过类库在每个网站上共享2个DBContext吗？

Answer 1

出于您的目的，您应使用自定义成员资格提供程序。这是关于它的文章的链接http://logcorner.wordpress.com/2013/08/29/how-to-configure-custom-membership-and-role-provider-using-asp-net-mvc4/。关于如何创建自定义成员资格提供程序

，还有How do I create a custom membership provider for ASP.NET MVC 2?

自定义成员资格提供程序的示例（请注意这是我的旧代码，因此您应该尝试对其进行优化）：

public class UsersProvider : RoleProvider
 {

     public override void AddUsersToRoles(string[] username, string[] roleName)
    {
        using (SmaCareEntities db = new SmaCareEntities())
        {
            List<int> ulist = (from u in db.Users
                               where username.Contains(u.UserName)
                               select u.RoleId).ToList();

            List<int> rlist = (from r in db.Roles
                               where roleName.Contains(r.Name)
                               select r.Id).ToList();


            var urlist = (from r in rlist
                          select new Role { Id = r }).FirstOrDefault();
            db.Roles.Attach(urlist);
            db.ObjectStateManager.ChangeObjectState(urlist, EntityState.Modified);
            db.SaveChanges();

        }
    }

    public override string ApplicationName
    {
        get
        {
            throw new NotImplementedException();
        }
        set
        {
            throw new NotImplementedException();
        }
    }

    public override void CreateRole(string roleName)
    {
        throw new NotImplementedException();
    }

    public override bool DeleteRole(string roleName, bool throwOnPopulatedRole)
    {
        throw new NotImplementedException();
    }

    public override string[] FindUsersInRole(string roleName, string usernameToMatch)
    {
        using (SmaCareEntities db = new SmaCareEntities())
        {

            User user = db.Users.FirstOrDefault(u => u.UserName.Equals(usernameToMatch, StringComparison.CurrentCultureIgnoreCase) || u.Email.Equals(usernameToMatch, StringComparison.InvariantCultureIgnoreCase));
            var roles = from r in db.Roles
                        where user.RoleId == r.Id
                        select r.Name;
            if (roles != null)
                return roles.ToArray();
            else return null;

        }

    }

    public override string[] GetAllRoles()
    {
        throw new NotImplementedException();
    }

    public override string[] GetRolesForUser(string username)
    {
        using (SmaCareEntities db = new SmaCareEntities())
        {

            User user = db.Users.FirstOrDefault(u => u.UserName.Equals(username, StringComparison.CurrentCultureIgnoreCase) || u.Email.Equals(username, StringComparison.InvariantCultureIgnoreCase));
            var roles = user.Role.Name;

            if (roles != null)
                return new string[] {roles};
            else
                return new string[] { };

        }
    }

    public override string[] GetUsersInRole(string roleName)
    {
        throw new NotImplementedException();
    }

    public override bool IsUserInRole(string username, string roleName)
    {
        using (SmaCareEntities db = new SmaCareEntities())
        {
            User user = db.Users.FirstOrDefault(u => u.UserName.Equals(username, StringComparison.CurrentCultureIgnoreCase) || u.Email.Equals(username, StringComparison.CurrentCultureIgnoreCase));
            if (user != null)
            {
                var roles = user.Role.Name;

                if (user != null)
                    return roles.Equals(roleName, StringComparison.CurrentCultureIgnoreCase);
                else
                {
                    return false;
                }
            }
            else
                return false;

        }
    }

    public override void RemoveUsersFromRoles(string[] usernames, string[] roleNames)
    {
        throw new NotImplementedException();
    }

    public override bool RoleExists(string roleName)
    {
        throw new NotImplementedException();
    }
}

用法示例：

    [Authorize(Roles = "Administrator")]   // this is the line where your membership provider checks if current user in "Administrator" role
    public ActionResult ProductList(string keyword, int? page)
    {
        return View(MainService.GetProducts(keyword, page));
    }

    [Authorize(Roles = "Administrator")]
    public ActionResult Delete(int id)
    {
        MainService.Delete(id);
        return RedirectToAction("ProductList");
    }

请勿忘记在web.config文件中添加此内容：

<roleManager enabled="true" defaultProvider="UsersProvider"> <providers> <clear/> <add name="UsersProvider" type="BusinessLogic.Users.UsersProvider" /> </providers>

此外，在您的数据库中，您应该有一个User表和一个{1}}表，其中包含1到N的关系（在Role表中使用foreign key - Id_role）< / p>
