Azure Automation在Hybrid Worker上调用内部应用程序Rest API，返回400错误

Question

我正在尝试构建Azure自动化Runbook来解锁本地AD帐户。解锁帐户后，我想向具有API的ITSM应用程序提交票证。我能够在Windows PowerShell中在服务器上创建调用，并获得200的返回代码。

但是，当我从Azure自动化运行它时，我收到错误代码400错误请求。有关为什么我可以使用Windows PowerShell在服务器上进行调用而不在混合工作者上使用Azure自动化进行调用的任何想法？

Custom_ITSM_API_Module的模块是一个自行开发的模块，可以在我尝试过的每个地方工作。它适用于我的开发计算机（Windows PowerShell）和混合工作服务器（Windows PowerShell），但不适用于使用Azure自动化。

码：

Param
([object]$WebhookData) #this parameter name needs to be called WebHookData otherwise the webhook does not work as expected.
$VerbosePreference = 'continue'

Import-Module ActiveDirectory
Import-Module "Custom_ITSM_API_Module"

#region Verify if Runbook is started from Webhook.

# If runbook was called from Webhook, WebhookData will not be null.
if ($WebHookData){

# Collect properties of WebhookData
$WebhookName     =     $WebHookData.WebhookName
$WebhookHeaders  =     $WebHookData.RequestHeader
$WebhookBody     =     $WebHookData.RequestBody

# Collect individual headers. Input converted from JSON.
$From = $WebhookHeaders.From
$RequestData = (ConvertFrom-Json -InputObject $WebhookBody)
Write-Output -InputObject ('Input: {0}' -f $RequestData )
Write-Output ('WebhookBody: {0}' -f $WebhookBody)
Write-Output -InputObject ('Runbook started from webhook {0} by {1}.' -f $WebhookName, $From)

$User = Get-ADUser $RequestData.SamAccountName -Properties *
If($User.SamAccountName.count -ne 1 ){
throw "Found $($User.SamAccountName.count) user(s). Please make sure this user is unique"
}
else{
    Write-Output "Unlocking User"
    Unlock-ADAccount -Identity $User

    $RanByEmployeeID = $RequestData.RanByEmployeeID
    $Runby = Get-ADUser -Filter {EmployeeID -eq $RanByEmployeeID} -Properties EmployeeID
    $Description = "User Unlcoked<br>EmployeeID: $($User.EmployeeID)<br>SamAccountName: $($User.SamAccountName)<br>Unlocked at: $((Get-Date).ToString())"
    Write-Custom_ITSM_API_ModuleTicket -Title "Unlocked User $($User.Name)"-Description $Description

  }
}
else{
   Write-Error -Message 'Runbook was not started from Webhook' -ErrorAction stop
}

我遇到的问题实际上是我们的防火墙和代理问题。这些服务器无法与建议的所有Azure / O365 URL进行通信。一旦我们将所有URL列入白名单，我就能够与我的内部应用程序通信。
