Gzip 压缩不起作用 ASP.net MVC5
Gzip compression not working ASP.net MVC5
我想用 Gzip 压缩我的 Web 应用程序,我正在使用以下 class
压缩过滤器
public class CompressFilter : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
HttpRequestBase request = filterContext.HttpContext.Request;
string acceptEncoding = request.Headers["Accept-Encoding"];
if (string.IsNullOrEmpty(acceptEncoding)) return;
acceptEncoding = acceptEncoding.ToUpperInvariant();
HttpResponseBase 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);
}
}
}
缓存过滤器
public class CacheFilterAttribute : ActionFilterAttribute
{
public int Duration
{
get;
set;
}
public CacheFilterAttribute()
{
Duration = 1;
}
public override void OnActionExecuted(ActionExecutedContext filterContext)
{
if (Duration <= 0) return;
HttpCachePolicyBase cache = filterContext.HttpContext.Response.Cache;
TimeSpan cacheDuration = TimeSpan.FromMinutes(Duration);
cache.SetCacheability(HttpCacheability.Public);
cache.SetExpires(DateTime.Now.Add(cacheDuration));
cache.SetMaxAge(cacheDuration);
cache.AppendCacheExtension("must-revalidate, proxy-revalidate");
}
}
控制器
[CompressFilter]
[CacheFilter(Duration = 60)]
public ActionResult Index()
{}
并将此 class 应用于 Controller 中的 Action。但是在 firebug 它仍然显示 "Transfer-Encoding: chunked" ,但它应该是 "Transfer-Encoding: gzip".
我正在本地主机上测试它。
请告诉我我做错了什么?感谢致敬。
更新 缓存过滤器工作正常,但仍然没有 gzip 压缩,下面是 chrome.
中的响应 header

有什么方法可以让我完成这项工作,我真的需要帮助,谢谢
如果压缩配置正确,请检查您的本地 IIS。请参考以下 link 以正确配置 IIS 以进行 HTTP 压缩。
http://www.iis.net/configreference/system.webserver/httpcompression
如果您无法控制 IIS,只需将此添加到您的 Global.ASCX。在 Android、iPhone 和大多数 PC 浏览器上进行了测试。
protected void Application_BeginRequest(object sender, EventArgs e)
{
// Implement HTTP compression
HttpApplication app = (HttpApplication)sender;
// Retrieve accepted encodings
string encodings = app.Request.Headers.Get("Accept-Encoding");
if (encodings != null)
{
// Check the browser accepts deflate or gzip (deflate takes preference)
encodings = encodings.ToLower();
if (encodings.Contains("deflate"))
{
app.Response.Filter = new DeflateStream(app.Response.Filter, CompressionMode.Compress);
app.Response.AppendHeader("Content-Encoding", "deflate");
}
else if (encodings.Contains("gzip"))
{
app.Response.Filter = new GZipStream(app.Response.Filter, CompressionMode.Compress);
app.Response.AppendHeader("Content-Encoding", "gzip");
}
