c# – MVC 4 – GZIP压缩JSON ajax动作结果

问题

我在IIS 7.5上运行的MVC 4应用程序上有一个Telerik MVC UI网格,可以通过AJAX潜在地返回大量的JSON数据,在极端情况下为800kb或更多.由于有效载荷可能很大,我想要GZIP它.对于我的生活,我不能让它工作.

控制器的动作是：

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

   return Json(result);
}

fiddler报告：

已经尝试了

我已经确保在IIS中启用动态和静态压缩：

App 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>

我确定了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" />

我已经尝试了serverRuntime频繁HitThreshold需要修改的suggestion here.

有没有我失踪的东西？

解决方法

好吧,我似乎也需要在我的控制器里做一些事情：

根据以下提取自：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);
        }
    }

控制器中的使用：

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