Question

我使用HttpWebRequest / HttpWebResponse获取html文档，代码跟随运行但我无法将收到的流编码为html字符串：

        string uri = "https://myfavoritesite.come";
        HttpWebRequest webrequest = (HttpWebRequest)WebRequest.Create(uri);
        webrequest.KeepAlive = true;
        webrequest.Method = "GET";
        webrequest.ContentType = "text/html";
        webrequest.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
        //webrequest.Connection = "keep-alive";
        webrequest.Host = "cat.sabresonicweb.com";
        webrequest.Headers.Add("Accept-Encoding", "gzip, deflate");
        webrequest.Headers.Add("Accept-Language", "en-US,en;q=0.5");
        webrequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1; rv:18.0) Gecko/20100101 Firefox/18.0";

        HttpWebResponse webresponse = (HttpWebResponse)webrequest.GetResponse();

        Console.Write(webresponse.StatusCode);
        Stream receiveStream = webresponse.GetResponseStream();


        Encoding enc = System.Text.Encoding.GetEncoding(1252);//1252
        StreamReader loResponseStream = new
          StreamReader(receiveStream, enc);

        string Response = loResponseStream.ReadToEnd();

        loResponseStream.Close();
        webresponse.Close();

        Console.Write(Response);

所以，我使用下面的代码行来测试是否有成功的请求。

         Console.Write(webresponse.StatusCode);

屏幕上的结果还可以，这意味着发送了请求，但屏幕上显示的响应字符串不是html格式，这是如此奇怪：@ 32u％＆amp; $ ＆amp; ;（@ *＃Eeeuw

通过使用webrequest.Headers.Add("Accept-Encoding", "gzip, deflate");，您告诉服务器您了解压缩响应。删除该标头并使用正常的UTF8编码而不是您正在使用的1252。然后你应该得到正确的字符串。您可以使用System.Text.Encoding.UTF8。
