.NET MVC 简单实现GZIP

打算用GZIP来做压缩，之前在IIS6上做过，这个项目用MVC做，发现在.NET MVC下有更简单好用的办法来解决：写一个ActionFilter来实现GZIP，优点大家用了就知道，呵呵

    public class CompressAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            var acceptEncoding = filterContext.HttpContext.Request.Headers["Accept-Encoding"];
            if (!string.IsNullOrEmpty(acceptEncoding))
            {
                acceptEncoding = acceptEncoding.ToLower();
                var response = filterContext.HttpContext.Response;
                if (acceptEncoding.Contains("gzip"))
                {
                    response.AppendHeader("Content-encoding", "gzip");
                    response.Filter = new GZipStream(response.Filter, CompressionMode.Compress);
                }
                else if (acceptEncoding.Contains("deflate"))
                {
                    response.AppendHeader("Content-encoding", "deflate");
                    response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress);
                }
            }
        }
    }

用法：

        [Longin]
        [Compress]
        public ActionResult Index()
        {
            
                return View();
        }

只要在打算用GZIP压缩的Action上写上[Compress]就OK了，是不是很简单，呵呵～
