htmlagilitypack gzip 加密异常

我遇到了异常，gzip is not support。这就是我用来加载页面的全部内容，关于如何允许 gzip 有什么想法吗？

        HtmlWeb hwObject = new HtmlWeb();
        HtmlAgilityPack.HtmlDocument htmldocObject = hwObject.Load(siteURL);

您可以自己下载该页面，即使用派生自的类WebClient（或手动制作WebRequest和设置AutomaticDecompression )

public class GZipWebClient : WebClient
{
    protected override WebRequest GetWebRequest(Uri address)
    {
        HttpWebRequest request = (HttpWebRequest)base.GetWebRequest(address);
        request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
        return request;
    }
}

鉴于此你可以这样做：

string html;
using(var wc = new GZipWebClient())
  html = wc.DownloadString(siteUrl);

var htmldocObject = new HtmlDocument();
htmldocObject.LoadHtml(html);
