MVC里的GZIP压缩

利用GZIP将数据压缩

先写个类：

public class CompressFilterAttribute : ActionFilterAttribute
    {
        public override void OnResultExecuting(ResultExecutingContext filterContext)
        {
            string acceptEncoding = filterContext.HttpContext.Request.Headers["Accept-Encoding"];
            if (String.IsNullOrEmpty(acceptEncoding)) return;
            var response = filterContext.HttpContext.Response;
            acceptEncoding = acceptEncoding.ToUpperInvariant();
            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);
            }
        }
    }

在控制器里加个：

        [CompressFilter]
        public ActionResult QJMap()
        {
            return View();
        }
