登录的代码都是用网上找的代码改的，以前孔网是http，程序一直运行正常，不知道什么时候改成https了，然后就不能登录
在网上查了很多文章，又用周公的博客里提供他写的相应HttpWebRequest访问类也是不行，同样的代码登录百度就能成功
参数是用httpWatch跟踪的，请高手指点，代码可直接试，我建的测试帐户是：用户名：mytestbook 密码：testbook
调用代码：
string url = "https://user.kongfz.com/member/login.php";
string postData = "username=mytestbook&password=testbook&act=login&returnUrl=http%3A%2F%2Fwww.kongfz.com&sb=%E7%99%BB%E5%BD%95";
string retStr = HttpWebResponseUtility.CreatePostHttpResponse(url, postData, null, null, null, null);
这是周公博客上的HTTP请求辅助类，我改了下返回值
/// <summary>
/// /// 有关HTTP请求的辅助类
/// </summary>
public class HttpWebResponseUtility
{
private static readonly string DefaultUserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)";
public static string CreatePostHttpResponse(string url, string postData, int? timeout, string userAgent, Encoding requestEncoding, CookieCollection cookies)
{
if (string.IsNullOrEmpty(url))
{
throw new ArgumentNullException("url");
}
if (requestEncoding == null)
{
requestEncoding = Encoding.UTF8;
}
HttpWebRequest request = null; //如果是发送HTTPS请求
if (url.StartsWith("https", StringComparison.OrdinalIgnoreCase))
{
ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(CheckValidationResult);
request = WebRequest.Create(url) as HttpWebRequest;
request.ProtocolVersion = HttpVersion.Version10;
}
else
{
request = WebRequest.Create(url) as HttpWebRequest;
}
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
if (!string.IsNullOrEmpty(userAgent))
{
request.UserAgent = userAgent;
}
else
{
request.UserAgent = DefaultUserAgent;
}
if (timeout.HasValue)
{
request.Timeout = timeout.Value;
}
if (cookies != null)
{
request.CookieContainer = new CookieContainer();
request.CookieContainer.Add(cookies);
}
byte[] data = requestEncoding.GetBytes(postData);
using (Stream stream = request.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
HttpWebResponse httpWebResponse = (HttpWebResponse)request.GetResponse();
Stream responseStream = httpWebResponse.GetResponseStream();
StreamReader streamReader = new StreamReader(responseStream, requestEncoding == null ? Encoding.UTF8 : requestEncoding);
string html = streamReader.ReadToEnd();
streamReader.Close();
responseStream.Close();
request.Abort();
httpWebResponse.Close();
return html;
}
private static bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)

}
}
