如何在asp.net MVC中gzip内容？

Question

如何压缩asp.net mvc应用程序发送的输出？

Answer 1

这是我使用的(在这个时间段):

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
{...}

还有其他的变化,但这很有效.(顺便说一下,我使用BaseController上的[Compress]属性来保存项目中的重复,而上面的操作是在控制器的基础上进行的.

[编辑]如上文所述.为了简化使用,您还可以[Compress]在BaseController本身中包含oneshot,从而每个继承的子控制器默认访问该功能:

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