Script:

Answer 1

1. Exception setting "SecurityProtocol":
   "Cannot convert null to type "System.Net.SecurityProtocolType"
   due to enumeration values that are not valid.
   Specify one of the following enumeration values and try again.
   The possible enumeration values are "SystemDefault,Ssl3,Tls,Tls11,Tls12"."
   

   使用

   [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]"tls12, tls11, tls"
   

   或者只是

   [Net.ServicePointManager]::SecurityProtocol = "tls12, tls11, tls"
   

   我得到以下错误

   There is no Runspace available to run scripts in this thread.
   
   You can provide one in the DefaultRunspace property
   of the System.Management.Automation.Runspaces.Runspace type.
   
   The script block you attempted to invoke was: $true
   

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

   add-type @"
       using System.Net;
       using System.Security.Cryptography.X509Certificates;
       public class TrustAllCertsPolicy : ICertificatePolicy {
           public bool CheckValidationResult(
               ServicePoint srvPoint, X509Certificate certificate,
               WebRequest request, int certificateProblem) {
               return true;
           }
       }
   "@
   [System.Net.ServicePointManager]::CertificatePolicy = New-Object TrustAllCertsPolicy
