AI-generated summary

Authorization Filters handle authentication and authorization, Action Filters run before and after executing Action methods, Result Filters run after executing Action methods and generating results, and Exception Filters handle exceptions. Authorization Filters can be added globally in the ConfigureServices method, while they can also be added locally in controller classes or action methods using the [Authorize] attribute.

Authorization Filters：身份验证和鉴权
Action Filters：执行 Action 方法前、后
Result Filters：执行 Action 方法并生成结果之后
Exception Filters：处理异常

public void ConfigureServices(IServiceCollection services)

            .RequireAuthenticatedUser()
            .Build();
        config.Filters.Add(new AuthorizeFilter(policy));
    });
}
