现在我像这样装饰一个方法,以允许“成员”访问我的控制器动作

[Authorize(Roles="members")]

如何允许多个角色?例如,下面的不工作,但它显示了我正在尝试做什么(允许“成员”和“管理员”访问):

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

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;
    }
}

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

对于MVC4,使用枚举(UserRoles)与我的角色,我使用自定义AuthorizeAttribute。

在我的控制行动中,我做到了:

[CustomAuthorize(UserRoles.Admin, UserRoles.User)]
public ActionResult ChangePassword()
{
    return View();
}

我使用一个自定义的AuthorizeAttribute,像这样:

[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]
public class CustomAuthorize : AuthorizeAttribute
{
    private string[] UserProfilesRequired { get; set; }

    public CustomAuthorize(params object[] userProfilesRequired)
    {
        if (userProfilesRequired.Any(p => p.GetType().BaseType != typeof(Enum)))
            throw new ArgumentException("userProfilesRequired");

        this.UserProfilesRequired = userProfilesRequired.Select(p => Enum.GetName(p.GetType(), p)).ToArray();
    }

    public override void OnAuthorization(AuthorizationContext context)
    {
        bool authorized = false;

        foreach (var role in this.UserProfilesRequired)
            if (HttpContext.Current.User.IsInRole(role))
            {
                authorized = true;
                break;
            }

        if (!authorized)
        {
            var url = new UrlHelper(context.RequestContext);
            var logonUrl = url.Action("Http", "Error", new { Id = 401, Area = "" });
            context.Result = new RedirectResult(logonUrl);

            return;
        }
    }
}
