调用 API 时出现问题

Question

我们有两个 API 执行 POST 和 GET 请求。他们两个过去都工作得很好，但是 POST 的 API 开始出错：

Invoke-WebRequest : The underlying connection was: An unexpected error occurred on a receive.`

几天来我一直在努力研究，所有知识库都指向某种 SSL/TLS 并添加了这段代码：

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

但我从一开始就已经有了这段代码。但是，我找不到解决问题的方法。

OS : 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，这种情况一直持续到上周。

Answer 1

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

Answer 2

我正在处理从 API 检索数据的类似请求，我发现我将我的函数调用为 funName -val1 1234 val2 9999，而我的 seconda 参数中缺少“-”。一旦我修复它再次开始工作 funName -val1 1234 -val2 9999 。感谢 Whosebug 社区对此的帮助。
