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。

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")]

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

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。

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();
}

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;
    }
}
