另一种选择是使用一个单独的授权过滤器，但删除内部报价。

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

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)]

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;
        }
    }
}

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。

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();
}

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;
    }
}

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)]

Intent promptInstall = new Intent(android.content.Intent.ACTION_VIEW);
promptInstall.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
promptInstall.setDataAndType(Uri.parse("http://10.0.2.2:8081/MyAPPStore/apk/Teflouki.apk"), "application/vnd.android.package-archive" );

startActivity(promptInstall);

您可以使用授权策略 在Startup.cs

    services.AddAuthorization(options =>
    {
        options.AddPolicy("admin", policy => policy.RequireRole("SuperAdmin","Admin"));
        options.AddPolicy("teacher", policy => policy.RequireRole("SuperAdmin", "Admin", "Teacher"));
    });

在控制器文件中:

 [Authorize(Policy = "teacher")]
 [HttpGet("stats/{id}")]
 public async Task<IActionResult> getStudentStats(int id)
 { ... }

“教师”政策接受3个角色。

[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

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。
