netcore 下的policy授权自定义返回结果

目前一直在用policy做权限校验，但是好像组里需要将返回结果统一，之前用的都是直接继承AuthorizationHandler然后调用context.Fail()，但是这样会导致没办法自定义返回结果比如{code:403,msg:'未授权',data:null},

也百度了下https://q.cnblogs.com/q/120091/ 这里也说了3.0后就改掉了之前可以通过result来返回，但是现在不行了，之后又查了下资料无果，今天心血来潮直接用httpcontext来返回结果可以了。。。。。

直接上代码吧

public class ApiUrlPermissionHandler : AuthorizationHandler<ApiUrlPermissionRequirement> {     private readonly IHttpContextAccessor _accessor;     private readonly ILogger<ApiUrlPermissionHandler> _logger;     private readonly IPermissionWatchDog _permissionWatchDog;       public ApiUrlPermissionHandler(IHttpContextAccessor accessor,ILogger<ApiUrlPermissionHandler> logger, IPermissionWatchDog permissionWatchDog)     {         this._accessor = accessor;         this._logger = logger;         this._permissionWatchDog = permissionWatchDog;     }     protected override async Task HandleRequirementAsync(AuthorizationHandlerContext context, ApiUrlPermissionRequirement requirement)     {         var httpContext = _accessor.HttpContext;           var isAuthenticated = context.User.Identity.IsAuthenticated;         if (isAuthenticated)         {             var uid = httpContext.User.Claims.FirstOrDefault(s => s.Type == "uid")?.Value;             if (uid.IsNullOrWhiteSpace())             {                 context.Fail();                 return;             }             //判断是否有权限             var questUrl = httpContext.Request.Path.Value.ToLower();             if (!await _permissionWatchDog.PassApiPermAsync(uid, questUrl))             {                 context.Fail();                 return;             }             context.Succeed(requirement);         }         else         {             httpContext.Response.ContentType =  "application/json; charset=UTF-8";             await httpContext.Response.WriteAsync(JsonConvert.SerializeObject(new { a="123",b="435"}));             await httpContext.Response.Body.FlushAsync();             //context.Fail();         }     } }

　　有不对或者更好的方法希望园友提供指出谢谢
