如何在asp.netMVC?

以下是我使用的(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);
        }
    }
}

控制器中的用法:

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

还有其他的变体,但效果很好。(顺便说一句,我在BaseController上使用[Compress]属性来保存整个项目的复制,而上面的方法是逐个控制器地进行。

[编辑] [Compress] 因此,默认情况下,每个继承的子控制器都访问功能:

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

看一看 this article 它概述了一个巧妙的方法,利用行动过滤器。

例如:

[CompressFilter]
public void Category(string name, int? page)

作为额外的好处,它还包括一个缓存过滤器。

对于.NETCore2.1,有一个新的包可以使用(Microsoft.AspNetCore.ResponseCompression文件)

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();
    }
}
