在C#中从httpwebrequest中获取垃圾内容

Question

                HttpWebRequest requestTransaction;
                Uri uriTransact = new Uri(Url);
                requestTransaction = (HttpWebRequest)WebRequest.Create(uriTransact);
                requestTransaction.ContentType = "application/x-www-form-urlencoded";
                requestTransaction.Method = "Post";
                requestTransaction.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8";
                requestTransaction.KeepAlive = true;
                requestTransaction.Headers.Add("Cache-Control", "no-cache");
                requestTransaction.CookieContainer = cookies;
                requestTransaction.Headers.Add("Upgrade-Insecure-Requests", "1");
                requestTransaction.Headers.Add("Accept-Encoding", "gzip, deflate, br");
                requestTransaction.Headers.Add("Accept-Language", "en-US,en;q=0.9");
                requestTransaction.Host = host;
                requestTransaction.Headers.Add("Origin", requestOrigin);
                requestTransaction.Referer = requestReferer
                requestTransaction.UserAgent = "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36";


                byte[] sentData2 = Encoding.UTF8.GetBytes(postData2);
                requestTransaction.ContentLength = sentData2.Length;
                using (System.IO.Stream sendStream = requestTransaction.GetRequestStream())
                {
                    sendStream.Write(sentData2, 0, sentData2.Length);
                    sendStream.Close();
                }
                 using (var response = requestTransaction.GetResponse() as HttpWebResponse)
                {
                    var doc = new HtmlAgilityPack.HtmlDocument();
                    doc.Load(response.GetResponseStream());
                }

我也有同样的问题，结果是响应被压缩了。您可以移除

requestTransaction.Headers.Add("Accept-Encoding", "gzip, deflate, br");

不太确定br或者你可以添加

webRequest.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;

到您的HttpWebRequest，顾名思义，它将自动解压缩响应。
