HttpWebRequest乱码问题

Atai-Lu 2008-04-24 10:38:03



public static string getWebContent(string Url, string referer, string ch)

        {

            string strResult = "";

            try

            {

                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);

                request.Timeout = 30000;//设置连接超时时间

                request.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2; ccdotnet ; .NET CLR 1.1.4322; .NET CLR 2.0.50727)";

                request.Referer = referer;//设置标头

                request.AllowAutoRedirect = true;

                //不用缓存

                //request.Headers.Set("Pragma", "no-cache");//不用缓存的话，对方服务器返回500错误

                HttpWebResponse response = (HttpWebResponse)request.GetResponse();

                Stream streamReceive = response.GetResponseStream();

                Encoding encoding = Encoding.GetEncoding(ch);

                StreamReader streamReader = new StreamReader(streamReceive, encoding);

                strResult = streamReader.ReadToEnd();

            }

            catch (Exception ex) { HttpContext.Current.Response.Write(ex.ToString()); }

            return strResult;

        }

//编码设置为gb2312，目标网址编码也是gb2312，但是返回结果是乱码，有什么解决的办法没？

Encoding encoding = Encoding.GetEncoding("GBK");

byte[] data = encoding.GetBytes("xml=" + content);

HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(url);

myRequest.Method = "POST";

myRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2; .NET CLR 1.1.4322; .NET CLR 2.0.50727)";

myRequest.ContentType = "application/x-www-form-urlencoded;charset=utf-8";

myRequest.ContentLength = data.Length;

Stream newStream = myRequest.GetRequestStream();

newStream.Write(data, 0, data.Length);

newStream.Close();

HttpWebResponse response = (HttpWebResponse)myRequest.GetResponse();

switch (response.CharacterSet.ToLower())
{
case "utf-8":
encoding = System.Text.Encoding.GetEncoding("utf-8");
break;
case "gb2312":
encoding = System.Text.Encoding.GetEncoding("gb2312");
break;
default:
encoding = System.Text.Encoding.GetEncoding("utf-8");
break;
}

StreamReader sr = new StreamReader(response.GetResponseStream(), encoding);

s = sr.ReadToEnd();

response.Close();

这个乱码问题很是复杂,我也是,做一个网站,只有点击找回密码时,那张页面就出现乱码,其它页面都好好的.这个问题很是头痛,网站和空间的权限也是有关系的.
