另一个清晰的解决方案是使用常量来保持约定，并添加多个[Authorize]属性。看看这个:

public static class RolesConvention
{
    public const string Administrator = "Administrator";
    public const string Guest = "Guest";
}

然后在控制器中:

[Authorize(Roles = RolesConvention.Administrator )]
[Authorize(Roles = RolesConvention.Guest)]
[Produces("application/json")]
[Route("api/[controller]")]
public class MyController : Controller

如果你想使用自定义角色，你可以这样做:

CustomRoles类:

public static class CustomRoles
{
    public const string Administrator = "Administrador";
    public const string User = "Usuario";
}

使用

[Authorize(Roles = CustomRoles.Administrator +","+ CustomRoles.User)]

如果你的角色很少，也许你可以把它们结合起来(为了清晰起见):

public static class CustomRoles
{
     public const string Administrator = "Administrador";
     public const string User = "Usuario";
     public const string AdministratorOrUser = Administrator + "," + User;  
}

使用

[Authorize(Roles = CustomRoles.AdministratorOrUser)]

我把答案混在一起，提出了这个方法。

首先，我们为角色访问创建一个枚举。

public enum ERoleAccess
{
     [Description("Admin User")]
     Admin = 1,

     [Description("General User")]
     User = 2,

     [Description("Editor User")]
     Editor = 3,
}

其次，我们需要一个用于客户MVC授权的属性过滤器。

public class RolesAttribute:AuthorizeAttribute
{
   public RolesAttribute(params ERoleAccess[] roles)
   {
      Roles = string.Join(",", roles);
   }
}

最后，我们可以在控制器或动作上使用“RolesAttribute”。

[Roles(ERoleAccess.Admin, ERoleAccess.Editor, ERoleAccess.User)]

在这种方法中，我们使用可选字符串值的数量。 (1=管理员，2=用户，…)

它有助于减小令牌大小和比较性能。

一个可能的简化是子类AuthorizeAttribute:

public class RolesAttribute : AuthorizeAttribute
{
    public RolesAttribute(params string[] roles)
    {
        Roles = String.Join(",", roles);
    }
}

用法:

[Roles("members", "admin")]

从语义上看，它和Jim Schmehil的答案是一样的。

[Authorize(Roles="admin")]
[Authorize(Roles="members")]

将在需要AND时工作(由问题询问)，而此答案显示OR版本。 详见https://learn.microsoft.com/en-us/aspnet/core/security/authorization/roles?view=aspnetcore-6.0#adding-role-checks

添加子类AuthorizeRole.cs会更好

    [AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]
    class AuthorizeRoleAttribute : AuthorizeAttribute
    {
        public AuthorizeRoleAttribute(params Rolenames[] roles)
        {
            this.Roles = string.Join(",", roles.Select(r => Enum.GetName(r.GetType(), r)));
        }
        protected override void HandleUnauthorizedRequest(System.Web.Mvc.AuthorizationContext filterContext)
        {
            if (filterContext.HttpContext.Request.IsAuthenticated)
            {
                filterContext.Result = new RedirectToRouteResult(
                new RouteValueDictionary {
                  { "action", "Unauthorized" },
                  { "controller", "Home" },
                  { "area", "" }
                  }
              );
                //base.HandleUnauthorizedRequest(filterContext);
            }
            else
            {
                filterContext.Result = new RedirectToRouteResult(
                new RouteValueDictionary {
                  { "action", "Login" },
                  { "controller", "Account" },
                  { "area", "" },
                  { "returnUrl", HttpContext.Current.Request.Url }
                  }
              );
            }
        }
    }

如何使用这个

[AuthorizeRole(Rolenames.Admin,Rolenames.Member)]

public ActionResult Index()
{
return View();
}
