HttpWebResponse 获取网页乱码

1.  StreamReader获取字符串使用 Encoding.Default.
2.  检查HttpWebResponse.ContentEncoding是否包含恶心的 "GZIP"字符,如果是那么要多一步操作

3. string html = "";
   string url = "http://www.stats.gov.cn/tjsj/tjbz/tjyqhdmhcxhfdm/2018/11/1101.html";
   HttpWebRequest myReq = (HttpWebRequest)HttpWebRequest.Create(url);
   myReq.Timeout = 5000;//5s
   using (HttpWebResponse httpWResp = (HttpWebResponse)myReq.GetResponse())
   {
   Stream myStream = httpWResp.GetResponseStream();
   //如果包含GZIP,需要解压
   if (!string.IsNullOrEmpty(httpWResp.ContentEncoding) && httpWResp.ContentEncoding.ToUpper().IndexOf("GZIP") > -1)
   {
   System.IO.StreamReader sr =
   new System.IO.StreamReader(new GZipStream(myStream, CompressionMode.Decompress), Encoding.Default);
   html = sr.ReadToEnd();
   sr.Close();
   }
   else
   {
   StreamReader sr = new StreamReader(myStream, Encoding.Default);
   html = sr.ReadToEnd();
   sr.Close();
   }
   myStream.Close();
   httpWResp.Close();
