SSL / TSL issue

Question

I want to run a web scraper script on a server.

The current script collects html on the specified page.

$url = "http://websms"
 [net.httpWebRequest] $request = [net.webRequest]::create($url)
 [net.httpWebResponse] $response = $request.getResponse()
 $responseStream = $response.getResponseStream()
 $sr = new-object IO.StreamReader($responseStream)
 $result = $sr.ReadToEnd()

 $result

This works well on a typical web page. However, I want to run it on the server administration page, which, of course, requires login.

I thought, before trying to log in, I will try to clear the server login page. Running the above script I get the following result.

   Exception calling "GetResponse" with "0" argument(s): "The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel."
At C:\temp\web3.ps1:3 char:56
+  [net.httpWebResponse] $response = $request.getResponse <<<< ()
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : DotNetMethodException

Any idea on how to get around this problem, or maybe if you can point me in a different direction so that I can clear the elements from the admin html page.

Thanks guys!

Answer 1

This one liner will ignore SSL certificate errors:

[System.Net.ServicePointManager]::ServerCertificateValidationCallback = {$true}

, .

Answer 2

:

public bool AcceptAllCertifications(object sender, System.Security.Cryptography.X509Certificates.X509Certificate certification, System.Security.Cryptography.X509Certificates.X509Chain chain, System.Net.Security.SslPolicyErrors sslPolicyErrors)
{
    return true;
}
ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications);
