C # create an https request and use a pfx Certificate

The code for creating a Web request and obtaining the request data is as follows:

WebRequest req = WebRequest. Create (url );

Req. Time out = 15000;

WebResponse result = req. GetResponse ();

Stream ReceiveStream = result. GetResponseStream ();

To add a certificate to the Code, use the HttpWebRequest object for the request. The Code is as follows:

// Add the callback method for the Verification Certificate

ServicePointManager. ServerCertificateValidationCallback = new RemoteCertificateValidationCallback (ValidateServerCertificate );

HttpWebRequest httpRequest = (HttpWebRequest) HttpWebRequest. Create (strQueryURL );

X509Certificate cerCaiShang = new X509Certificate (System. Web. HttpContext. Current. Server. MapPath (setting. PfxFile), setting. key );

HttpRequest. ClientCertificates. Add (cerCaiShang );

HttpWebResponse httpResponse = (HttpWebResponse) httpRequest. GetResponse ();

Stream receiveStream = httpResponse. GetResponseStream ();

// Callback Method

Public static bool ValidateServerCertificate (object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)

{

If (sslPolicyErrors = SslPolicyErrors. None)

Return true;

Return false;

}
