.NET Core ActionFilterAttribute自定义响应输出

在.Net Core 中使用ActionFilterAttribute重写OnResultExecuting来实现对返回接口自定义输出：

1、创建 ResultFilter ，继承自 ActionFilterAttribute

public class ResultFilter : ActionFilterAttribute
    {

  /// <summary>
        /// 接口返回前验证
        /// </summary>
        /// <param name="context"></param>
        public override void OnResultExecuting(ResultExecutingContext context)
        {

if (context.Result is ObjectResult)
            {
                var objectResult = context.Result as ObjectResult;
                if (objectResult.StatusCode == 203)
                {
                    context.Result = new ObjectResult(new
                    {
                        code = objectResult.StatusCode,
                        msg = new { 
ip = $"{context.HttpContext.Connection.RemoteIpAddress}", 
info = objectResult.Value, 
date = DateTime.Now.ToString("G"), url = requestUrl 
},
                        result = obj
                    });
                }
if (context.Result is ContentResult)
            {
                context.Result = new ObjectResult(new { code = 200, msg = new { ip = $"{context.HttpContext.Connection.RemoteIpAddress}", info = "OK", date = DateTime.Now.ToString("G"), url = requestUrl }, result = (context.Result as ContentResult).Content });
            }
       }

   }
}

2、添加MVC服务配置过滤器

  public void ConfigureServices(IServiceCollection services)
        {


            services.AddControllers();

            services.AddMvc(options =>
            {
                options.Filters.Add(typeof(ResultFilter));
            });


        }

自定义响应优雅方式参考 .NET Core AutoWrapper 自定义响应输出
