问题描述
我正在使用httpwebrequest
和httpwebresonse
class访问网页,但是我面临一个问题.
问题:当我访问网页时,响应是,我得到的是具有SSL证书(https://Loginpage.)的登录页面,而不是要求的页面,它没有绕过登录页面.
我的代码在下面..
Hi ,
I am accessing web page by using httpwebrequest
and httpwebresonse
class''s, but i am facing one issue.
Issue : When i am accessing the web page, the response, i am getting for Login Page which has SSL certificate(https://Loginpage.) not for requsted page, it is not bypassing login page.
My code is below..
string strurl = "http://Requstedpage";
Uri uri = new Uri(strurl);
ServicePointManager.ServerCertificateValidationCallback +=
delegate(
object sender1,
X509Certificate certificate,
X509Chain chain,
SslPolicyErrors sslPolicyErrors)
{
return true;
};
HttpWebRequest request = HttpWebRequest.Create(uri) as HttpWebRequest;
request.ContentType = "application/x-www-form-urlencoded";
request.AllowAutoRedirect = true;
request.PreAuthenticate = true;
request.Credentials = CredentialCache.DefaultCredentials;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
string responseText = string.Empty;
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
responseText = reader.ReadToEnd();
response.Close();
string RespCookie = response.Cookies.ToString();
Response.Write(responseText);
推荐答案
public void ConfigureSSL()
{
ServicePointManager.ServerCertificateValidationCallback = CertChecker;
}
private bool CertChecker(object sender, X509Certificate certificate,
X509Chain chain, SslPolicyErrors errors)
{
return certificate.Subject == "Certificate SSL Subject for your site";//
}
在第一个请求之前调用ConfigureSSL()
方法.
Call ConfigureSSL()
method before the first request.
