执行 powershell 脚本时出错

Question

我正在尝试从 power shell 创建一个 Rest API，当我尝试运行脚本时出现以下错误。我不确定自己在犯什么错误。

我会把脚本和错误也放上去。请帮忙。

Script:
username = "admin"
password = "******"
authInfo = ("{0}:{1}" -f $username,$password)
authInfo = [System.text.Encoding]:: UTF8.GetByteCount($authInfo)
authInfo = [System.Convert]::ToBase64String($authInfo)
headers = @{Accept=("application/json");Contenttype=("appliaction/json");Authorization=("Basic {0}"-f $authInfo)}
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::"tls12, tls11, tls"
Invoke-WebRequest -Uri https://njidlsdsapp01/support

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

uri = "https://njidlsdsapp01/support"
body = "{'login':'admin','login_pwd':'*****','commands' :['create a new support file']}" 

标题

res = invoke-RestMethod -Uri $uri -Headers $headers -Method Post -Body $body
res

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"

1. 我收到以下错误

   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
   

这是一个已知的 PowerShell 问题，请尝试以下解决方法：Powershell v3 Invoke-WebRequest HTTPS error

替换

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

与

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
