我有这段代码可以从 URL 获取页面 HTML，但是响应内容看起来是经过编码的。

代码：

    HttpWebRequest xhr = (HttpWebRequest) WebRequest.Create(new Uri("https://www.youtube.com/watch?v=_Ewh75YGIGQ"));
        xhr.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
        //xhr.CookieContainer = request.Account.CookieContainer;
        xhr.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
        xhr.Headers["Accept-Encoding"] = "gzip, deflate, br";
        xhr.Headers["Accept-Language"] = "en-US,en;q=0.5";
        xhr.Headers["Upgrade-Insecure-Requests"] = "1";
        xhr.KeepAlive = true;
        xhr.UserAgent = "Mozilla/4.0 (compatible; MSIE 9.0; Windows NT 6.1)";
        xhr.Host = "www.youtube.com";
        xhr.Referer = "https://www.youtube.com/watch?v=6aCpYxzRkf4";
        var response = xhr.GetResponse();
        string html;
        using (StreamReader reader = new StreamReader(response.GetResponseStream()))
        {
            html = reader.ReadToEnd();
        }

这些是响应标头：
