急！搞了我一夜还是不行！GetResponseStream()返回乱码！怎么修改encoding都不成！求老师们帮帮忙！

using System;

using System.Collections.Generic;

using System.Text;

using System.IO;

using System.Net;

namespace alvvtest

{

    class Program

    {

        static void Main(string[] args)

        {

            string postzf = "pageindex=1";

            string url = "http://www.alivv.com/ajax/Alivv.AjaxRun.WebSiteAjax,Alivv.AjaxRun.ashx?_method=BuyerWebSiteList&_session=r";



            

                HttpWebRequest newqq = null;

                HttpWebResponse newfh = null;

             



                    System.Net.ServicePointManager.Expect100Continue = false;

                    Uri newurl = new Uri(url);

                    newqq = (HttpWebRequest)WebRequest.Create(newurl);

                    string data = postzf;

                    newqq.Host = "www.alivv.com";

                    newqq.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; GTB6; .NET CLR 2.0.50727; CIBA)";

                    newqq.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";

                    newqq.Headers.Add("Accept-Language", "zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3");

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

                    newqq.Headers.Add("DNT", "1");

                    newqq.ContentType = "text/plain; charset=UTF-8";



                    newqq.Referer = "http://www.alivv.com/links_gd.html";



                    newqq.CookieContainer = new CookieContainer() ;

                    newqq.Accept = "*/*";

                    newqq.Method = "POST";

                    newqq.Timeout = 60000;

                    //newqq.KeepAlive = true;  



                    //newqqt.AllowAutoRedirect = true;

                    byte[] byteArray = Encoding.UTF8.GetBytes(data);

                    Stream stream = newqq.GetRequestStream();



                    stream.Write(byteArray, 0, byteArray.Length);

                    stream.Close();

                    newfh = (HttpWebResponse)newqq.GetResponse();

                    StreamReader sr = new StreamReader(newfh.GetResponseStream(), Encoding.UTF8);

                    string fanhuizhi = sr.ReadToEnd();



                

            

        }

    }

}

最后的fanhuizhi是乱码不管怎么修改encoding都不行

目前我发现在头协议当中有一句：

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

难道说信息流通过压缩了？

还有就是post部分的代码是否正确呢？希望老师们帮我看一下，被这个问题搞死了！

附上正常返回的值：

    Stream responseStream = responseStream = WebResponse.GetResponseStream();
    if (WebResponse.ContentEncoding.ToLower().Contains("gzip"))
        responseStream = new GZipStream(responseStream, CompressionMode.Decompress);
    else if (WebResponse.ContentEncoding.ToLower().Contains("deflate"))
        responseStream = new DeflateStream(responseStream, CompressionMode.Decompress);

    StreamReader Reader = new StreamReader(responseStream, Encoding.Default);

    string Html = Reader.ReadToEnd();

request.AutomaticDecompression = DecompressionMethods.GZip Or DecompressionMethods.Deflate

引用 2 楼的回复:

HttpWebResponse WebResponse = (HttpWebResponse)Http.GetResponse();

Stream responseStream = responseStream = WebResponse.GetResponseStream();
if (WebResponse.ContentEncoding.ToLower().Con……

正解！ StreamReader Reader = new StreamReader(responseStream, Encoding.Default);后的Encoding是关键

补充：.NET技术 ,  C#
