急救，有关http post的问题

[ 2006/12/9 15:03:49 | By: 玻璃杯中的花生壳 ]

我现在向一个站点模拟一个POST请求，其实就是模拟登录这个站点。用户名跟密码是绝对没问题的，在IE上登录都可以，但用POST模拟发送出现问题了。代码如下：string postData = "uUsername=abc&uPassword=ccc";byte[] data = System.Text.Encoding.GetEncoding("GB2312").GetBytes(postData) ;string postUrl = "http://wwww.aaa.com"; // 准备请求...HttpWebRequest req = (HttpWebRequest)WebRequest.Create(postUrl); try{req.Method = "post" ;req.ContentType ="application/x-www-form-urlencoded";req.ContentLength = data.Length;Stream stream = req.GetRequestStream() ; // 发送数据stream.Write (data ,0 ,data.Length ) ;stream.Close () ; HttpWebResponse rep = (HttpWebResponse)req.GetResponse();Stream receiveStream = rep.GetResponseStream();Encoding encode = System.Text.Encoding.GetEncoding("GB2312");StreamReader readStream = new StreamReader( receiveStream, encode ); Char[] read = new Char[256];int count = readStream.Read( read, 0, 256 );StringBuilder sb = new StringBuilder("") ;while (count > 0) {String readstr = new String(read, 0, count);sb.Append (readstr) ;count = readStream.Read(read, 0, 256);}rep.Close();readStream.Close();Response.Write(sb.ToString()); Response.Write("Login success!");return true;}catch(Exception ex){Response.Write("Login error:"+ex.Message.ToString());return false;}返回：远程服务器返回错误: (403) 已禁止。所以，我在本地建了一个接收POST地址的URL，部份代码如下：string uUsername = Request.Form["uUsername"];string uPassword = Request.Form["uPassword"];if (uUsername!=null && uUsername !=""){Response.Write("post data:uUsername"+uUsername+",uPassword:"+uPassword);}else{Response.Write("post data null!");}都接收成功，就在就纳闷了。按理来说，我的模拟POST请求的代码应该是没问题的。但POST服务器上就是有错误，望高手指点！http://community.csdn.net/Expert/topic/4887/4887171.xml
