        string documentName;

        public ActionDesc(string documentName)
        {
            this.documentName = documentName;
        }

        public void Apply(OpenApiOperation operation, OperationFilterContext context)
        {
            //过滤处理
            //context.ApiDescription.ActionDescriptor.FilterDescriptors;
            var attrs = context.MethodInfo.GetCustomAttributes(true);
            //context.ApiDescription.ActionDescriptor.DisplayName += "helloworld";
            if (attrs != null && attrs.Length > 0)
            {
                if (attrs.Any(f => f.GetType() == typeof(HttpGetAttribute)))
                {
                    //添加需要的注释
                    operation.Description += " This is a GET method action";
                }
            }
        }
    }
