使用AspNetCore 2。X，你必须走不同的路:

[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]
public class AuthorizeRoleAttribute : AuthorizeAttribute
{
    public AuthorizeRoleAttribute(params YourEnum[] roles)
    {
        Policy = string.Join(",", roles.Select(r => r.GetDescription()));
    }
}

就像这样使用它:

[Authorize(YourEnum.Role1, YourEnum.Role2)]

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

如果您发现自己经常应用这两个角色，您可以将它们包装在自己的Authorize中。这实际上是公认答案的延伸。

using System.Web.Mvc;

public class AuthorizeAdminOrMember : AuthorizeAttribute
{
    public AuthorizeAdminOrMember()
    {
        Roles = "members, admin";
    }
}

然后将新的授权应用到Action。我觉得这样看起来更干净，也更容易读。

public class MyController : Controller
{
    [AuthorizeAdminOrMember]
    public ActionResult MyAction()
    {
        return null;
    }
}

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。

使用AspNetCore 2。X，你必须走不同的路:

[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]
public class AuthorizeRoleAttribute : AuthorizeAttribute
{
    public AuthorizeRoleAttribute(params YourEnum[] roles)
    {
        Policy = string.Join(",", roles.Select(r => r.GetDescription()));
    }
}

就像这样使用它:

[Authorize(YourEnum.Role1, YourEnum.Role2)]

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)]
