Power Shell Web Scraping SSL/TSL問題

Question

我想在服務器上運行Web抓取腳本。

當前腳本收集指定頁面上的html。

$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 

這在一個典型的網頁上正常工作。不過，我想在服務器管理頁面上運行它，當然這需要登錄。

我想在我嘗試登錄之前，我會嘗試和颳去服務器的登錄頁面。運行上面的腳本，我得到以下結果。

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 

如何來解決這個問題，或者是如果你能指出我不同的方向，所以我可以颳去的服務器的管理員HTML頁面元素的任何想法。

謝謝！

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

錯誤將在此之後被忽略被執行。

使用this brilliant answer：

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);
