Windows 调用API时出现的问题

我们有两个API来执行POST和GET请求。它们过去都工作得很好，但进行POST的API开始出现错误：

Invoke WebRequest:基础连接为：接收时发生意外错误`

我已经尝试研究了几天，所有KBs都指向某种SSL/TLS，并添加了以下代码：

[Net.ServicePointManager]::SecurityProtocol = "SystemDefault,Tls12, Tls11, Tls, Ssl3"

但是我从一开始就已经有了这个代码。然而，我找不到解决我问题的办法

操作系统：Windows 2012
PowerShell版本：4.0

function funName ($Val1, $Val2) {
    [Net.ServicePointManager]::SecurityProtocol = "SystemDefault,Tls12, Tls11, Tls, Ssl3"
    #[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
    #[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls -bor [Net.SecurityProtocolType]::Tls11 -bor [Net.SecurityProtocolType]::Tls12

    $url = "https://someAPI/post.request/do-something"
    $user = "username"
    $pass = "password"
    $pair = "$($user):$($pass)"
    $encodedCreds = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes($pair))
    $basicAuthValue = "Basic $encodedCreds "

    $Headers = @{
        "Accept"="application/json"
        Authorization = $basicAuthValue
    }

    $Body = @{
        '@type' ='x'
        parm1 = $Val1
        parm2 = $Val2
    }

    #[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12 
    Invoke-WebRequest -Uri $url -Headers $Headers -Method Post -Body $Body  | Out-Null
}

## Deactivation Request ffffffff##
funName -RequestID Val1 adID Val2

如前所述，这在上周之前一直有效。

将其设置为脚本的顶部：

Add-Type @"
    using System.Net;
    using System.Security.Cryptography.X509Certificates;

    namespace myTrust
    {
        public class TrustAllCertsPolicy : ICertificatePolicy 
        {
            public bool CheckValidationResult( ServicePoint srvPoint, X509Certificate certificate, WebRequest request, int certificateProblem) 
            {
                return true;
            }
        }
    }
"@

$AllProtocols = [System.Net.SecurityProtocolType]'Ssl3,Tls,Tls11,Tls12'
[System.Net.ServicePointManager]::SecurityProtocol = $AllProtocols
[System.Net.ServicePointManager]::CertificatePolicy = New-Object myTrust.TrustAllCertsPolicy

我正在处理一个类似的请求，以从API检索数据，我发现我正在调用我的函数，在我的第二个a参数中，我的名字是

funName-val1 1234 val2 9999

where is missing“-”。一旦我确定它重新开始工作

funName-val1 1234-val2 9999

。感谢Stackoverflow社区在此方面提供的帮助。

这可能是一个愚蠢的问题，但您是否验证了证书未过期？否。证书未过期
