C#调用WinHttp.WinHttpRequest.5.1 Get网页 乱码问题

[woshiklc]

            WinHttp winhttp = new WinHttp();
            string content = winhttp.Open("GET", "http://su.58.com/", false);
            winhttp.Post();

            object obj;
            obj = HttpObj.DoMethod("Open", new object[] { OpenMethod, URL, Async });
            if (obj != null)
            {
                _Active = false;
                return obj.ToString();
            }
            else

                    AdoStream.DoMethod("Write", new object[1] { HttpObj["ResponseBody"] });
                    AdoStream["Position"] = 0;
                    AdoStream["Type"] = 2;
                    AdoStream["Charset"] = "UTF-8";//这里的编码和网页上的一样
                    
//                     GZipStream g = new GZipStream((Stream)AdoStream, CompressionMode.Decompress);

AdoStream["Charset"] = "gb2312";

引用 1 楼 wawd74520 的回复:

AdoStream["Charset"] = "gb2312";

也是乱码。。。。我试了 是否需要GZIP解压缩呢？

public static string doGet(string Url)

            try
            {
                HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(Url.ToString());
                myRequest.ServicePoint.Expect100Continue = true;
                myRequest.Method = "GET";
                myRequest.Timeout = 6000;
                myRequest.KeepAlive = true;//modify by yang
                myRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0)";
                myRequest.ContentType = "application/x-www-form-urlencoded";
                HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();
                StreamReader reader = new StreamReader(myResponse.GetResponseStream(), Encoding.GetEncoding("utf-8"));
                string outdata = reader.ReadToEnd();
                reader.Close();
                return outdata;
            }
            catch (Exception ex)
            {
                return ex.Message;
            }
        }

try 也可以使用默认的 SetRequestHeader("Accept-Encoding", "gzip,deflate,sdch");这个不要试试

楼主你用这个Adodb.Stream 是ASP的产物。。是COM+组件研究这做啥。。基本没人用这东西了。
