Here's what i use (as of this monent in time):
这是我使用的（截至目前）：
using System.IO.Compression;
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);
}
}
}
usage in controller:
在控制器中的用法：
[Compress]
public class BookingController : BaseController
{...}
there are other varients, but this works quite well. (btw, i use the [Compress] attribute on my BaseController to save duplication across the project, whereas the above is doing it on a controller by controller basis.
还有其他变体，但这很有效。（顺便说一句，我在我的 BaseController 上使用 [Compress] 属性来保存整个项目中的重复，而上述操作是在一个控制器一个控制器的基础上进行的。
[Edit]as mentioned in the para above. to simplify usage, you can also include [Compress]oneshot in the BaseController itself, thereby, every inherited child controller accesses the functionality by default:
[编辑]如上段所述。为了简化使用，您还可以[Compress]在 BaseController 本身中包含oneshot，从而默认情况下每个继承的子控制器都会访问该功能：
[Compress]
public class BaseController : Controller
{...}

Have a look at this articlewhich outlines a nifty method utilizing Action Filters.
看看这篇文章，它概述了一个利用动作过滤器的漂亮方法。
For example:
例如：
[CompressFilter]
public void Category(string name, int? page)
And as an added bonus, it also includes a CacheFilter.
作为额外的奖励，它还包括一个 CacheFilter。

For .NET Core 2.1 there is a new package that can be used ( Microsoft.AspNetCore.ResponseCompression )
对于 .NET Core 2.1，有一个可以使用的新包（ Microsoft.AspNetCore.ResponseCompression ）
Simple sample to get going, after installing the package:
安装软件包后，开始使用的简单示例：
public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddResponseCompression();
services.AddResponseCompression(options =>
{
options.Providers.Add<GzipCompressionProvider>();
options.EnableForHttps = true;
});
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
app.UseResponseCompression();
}
}
