在进行依赖注入的时候，添加进去：
```csharp
            // 过滤器
            services.AddControllers(options =>
            {
                options.Filters.Add<WebGlobalExceptionFilter>();
                options.Filters.Add<ActionInvalidModelFilter>();
                options.Filters.Add<ResourceFilter>();
            })
