MVC 4 - JSON ajax 操作结果的 GZIP 压缩

MVC 4 - GZIP compression of JSON ajax action result

问题

我在 IIS 7.5 上的 MVC 4 应用程序 运行 上有一个 Telerik MVC UI 网格,它可能 return 大量 JSON 数据通过 AJAX,在极端情况下为 800kb 或更多。由于有效负载可能很大,我想对其进行 GZIP 压缩。对于我的一生,我无法让它工作。

控制器动作是:

public ActionResult _CustomBinding([DataSourceRequest] DataSourceRequest request, SearchMemberModel search)
{
    //Do some stuff

   return Json(result);
}

Fiddler 报告:

已经尝试过的

我已确保在 IIS 中启用了动态和静态压缩:

应用Web.Config修改:

  <system.webServer>
    <serverRuntime frequentHitThreshold="1" frequentHitTimePeriod="10:00:00" />

    <validation validateIntegratedModeConfiguration="false" />
    <modules runAllManagedModulesForAllRequests="false">
      <remove name="FormsAuthentication" />
    </modules>

    <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">

      <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" staticCompressionLevel="9"  />
      <dynamicTypes>
        <add mimeType="text/*" enabled="true" />
        <add mimeType="message/*" enabled="true" />
        <add mimeType="application/x-javascript" enabled="true" />
        <add mimeType="application/json" enabled="true" />
        <add mimeType="*/*" enabled="false" />
      </dynamicTypes>
      <staticTypes>
        <add mimeType="text/*" enabled="true" />
        <add mimeType="message/*" enabled="true" />
        <add mimeType="application/x-javascript" enabled="true" />
        <add mimeType="application/atom+xml" enabled="true" />
        <add mimeType="application/xaml+xml" enabled="true" />
        <add mimeType="*/*" enabled="false" />
      </staticTypes>
    </httpCompression>

    <urlCompression doStaticCompression="true" doDynamicCompression="true" />

  </system.webServer>

我已经确定ApplicationHost file has the right mime types

    <add mimeType="application/json" enabled="true" />
    <add mimeType="application/json; charset=utf-8" enabled="true" />
    <add mimeType="application/json;charset=utf-8" enabled="true" />

我试过 suggestion here serverRuntime frequentHitThreshold 需要修改。

有什么我遗漏的吗?

好的,看来我还需要在我的控制器中做一些事情:

根据以下摘自:how to gzip content in asp.net MVC?

public class CompressAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {

        var encodingsAccepted = filterContext.HttpContext.Request.Headers["Accept-Encoding"];
        if (string.IsNullOrEmpty(encodingsAccepted)) return;

        encodingsAccepted = encodingsAccepted.ToLowerInvariant();
        var response = filterContext.HttpContext.Response;

        if (encodingsAccepted.Contains("deflate"))
        {
            response.AppendHeader("Content-encoding", "deflate");
            response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress);
        }
        else if (encodingsAccepted.Contains("gzip"))
        {
            response.AppendHeader("Content-encoding", "gzip");
            response.Filter = new GZipStream(response.Filter, CompressionMode.Compress);
        }
    }

在控制器中的用法:

[Compress]
public class BookingController : BaseController
{...}
