如果要在将HTML发送到客户端时压缩HTML,请应用此压缩过滤器以获取最快的包交付速度。
ActionFilters\CompressFilter.cs
public class CompressFilter : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
bool allowCompression = false;
bool.TryParse(ConfigurationManager.AppSettings["Compression"], out allowCompression);
if (allowCompression)
{
HttpRequestBase request = filterContext.HttpContext.Request;
string acceptEncoding = request.Headers["Accept-Encoding"];
if (string.IsNullOrEmpty(acceptEncoding)) return;
acceptEncoding = acceptEncoding.ToUpperInvariant();
HttpResponseBase response = filterContext.HttpContext.Response;
if (acceptEncoding.Contains("GZIP"))
{
response.AppendHeader("Content-encoding", "gzip");
response.Filter = new GZipStream(response.Filter, CompressionMode.Compress);
}
else if (acceptEncoding.Contains("DEFLATE"))
{
response.AppendHeader("Content-encoding", "deflate");
response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress);
}
}
}
}
