VerifySignatureAttribute是Attribute，注入有几种办法，参考下面链接
https://www.andybutland.dev/2020/06/dependency-injection-in-aspnet-core-attributes.html

最简单的就是直接用ActionExecutingContext filterContext

var redisCacheService = filterContext.HttpContext.RequestServices.GetRequiredService<IRedisCacheService>();
var appSecretModel = await filterContext.HttpContext.RequestServices.GetRequiredService<IAppSecretService>().FirstAsync(x => x.IsDeleted == false && x.AppId == appId);

对于 TokenFilterAttribute.cs

    //private readonly IHttpContextAccessor _accessor = AutofacHelper.GetService<IHttpContextAccessor>();
    //private readonly ICurrentUser _currentUser = AutofacHelper.GetService<ICurrentUser>();
    public override async Task OnActionExecuting(ActionExecutingContext context)
    {
        try
        {
            var accessor = context.HttpContext.RequestServices.GetRequiredService<IHttpContextAccessor>();
            var currentUser = context.HttpContext.RequestServices.GetRequiredService<ICurrentUser>();

下面基于TypeFilterAttribute的定义技巧我觉得也不错，这样将过滤器用于给定的控制器或操作方法不过于冗长
对这个感兴趣，可以阅读下文中的链接。

public class AddRandomNumberHeader2Attribute : TypeFilterAttribute
    {
        public AddRandomNumberHeader2Attribute() : base(typeof(AddRandomNumberHeader2Filter))
        {
        }

        private class AddRandomNumberHeader2Filter : IResultFilter
        {
            private readonly IRandomNumberService _randomNumberService;

            public AddRandomNumberHeader2Filter(IRandomNumberService randomNumberService)
            {
                _randomNumberService = randomNumberService;
            }

            public void OnResultExecuted(ResultExecutedContext context)
            {
            }

            public void OnResultExecuting(ResultExecutingContext context)
            {
                context.HttpContext.Response.Headers.Add("X_Random_Number_3", _randomNumberService.GetRandomInteger().ToString());
            }
        }
    }

        [AddRandomNumberHeader2]
        public IActionResult Index()
        {
            return Content("Hello world.");
        }
