ASP.NET MVC Gzip 压缩

原作者地址

写一个ActionFilter来实现GZIP：

CompressFilterAttribute.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.IO;
using System.IO.Compression;

namespace MyMVC.ActionFilters
{
    public classCompressFilterAttribute:ActionFilterAttribute
    {
       public override void OnResultExecuting(ResultExecutingContextfilterContext)
       {
           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controller文件中

       [CompressFilter]
       public ActionResult Compress()
       {
           return this.View();
       }
