HttpWebRequest请求：
string postData = "inputCode="+this.textBox3.Text;//验证码
postData += ("&configKey=ZJ2t2ofiM9Ikpv4JE8Dctg==");
request =
(HttpWebRequest)WebRequest.Create("http://www.10010.com/mall-web/OlympicActivityCaptcha/check");
Encoding encoding = Encoding.GetEncoding("utf-8");
byte[] data = encoding.GetBytes(postData.ToString());
request.ContentType = "text/html";
request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; rv:14.0) Gecko/20100101 Firefox/14.0.1";
request.ContentLength = data.Length;
request.Referer = "http://www.10010.com/mall-web/OlympicActivityCaptcha/input";
request.CookieContainer = cookie;
request.Host = "10010.com";
request.Timeout = 10000;
request.Accept = "zh-CN";
request.Method = "POST";
Stream newStream = request.GetRequestStream();
Application.DoEvents();
// Send the data.
newStream.Write(data, 0, data.Length);
newStream.Close();
response = (HttpWebResponse)request.GetResponse();//404错误
string url = response.ResponseUri.ToString();
StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding("utf-8"));
