PowerShell 中 Power BI Rest API 的错误处理

Question

我正在尝试为我的 PowerBI 休息 API 在 PowerShell 中遇到错误时创建一个自动电子邮件系统。基本上，我的 PowerBI RestAPI 有时会出现以下错误：

每当出现此错误时，我希望我的 PowerShell 脚本给我发送一封电子邮件。我目前正在测试以下代码，但它根本不起作用。理想情况下，当以下代码发生错误时，它应该打印 "Error"。相反，它只是打印错误并停止。我想知道是否有人有使用 PowerBI rest API 进行错误处理的经验。

$User = "email@hotmail.com"
$PW = "mypw"

$SecPasswd = ConvertTo-SecureString $PW -AsPlainText -Force
$myCred = New-Object System.Management.Automation.PSCredential($User,$SecPasswd)

Connect-PowerBIServiceAccount -Credential $myCred

# 2. Refresh Dataset
try{
Invoke-PowerBIRestMethod -Url "datasets/2-cdaf123fa5/refreshes" -Method Post -Body '{"notifyOption": "MailOnFailure"}'
}

# 3. Check if there is an error
catch {
            $emailSmtpServer = "smtp.gmail.com"
            $emailSmtpServerPort = "587"
            $emailSmtpUser = "email@gmail.com"
            $emailSmtpPass = "password"

            $emailFrom = "email@gmail.com"
            $emailTo = "email@gmail.com"

            $emailMessage = New-Object System.Net.Mail.MailMessage( $emailFrom , $emailTo )
            $emailMessage.Subject = "subject" 
            $emailMessage.Body = "body"

            $SMTPClient = New-Object System.Net.Mail.SmtpClient( $emailSmtpServer , $emailSmtpServerPort )
            $SMTPClient.EnableSsl = $True
            $SMTPClient.Credentials = New-Object System.Net.NetworkCredential( $emailSmtpUser , $emailSmtpPass );
            $SMTPClient.Send( $emailMessage )
    }

处理这个问题的方法很少。你有一个非终止错误。如果我的解决方案不符合您的需求，您可以返回上面的 link 并搜索下面的问题。

Try/Catch/Finally The Try/Catch/Finally statements, added in PowerShell 2.0, are the preferred way of handling terminating errors. They cannot be used to handle non-terminating errors, unless you force those errors to become terminating errors with ErrorAction or $ErrorActionPreference set to Stop.

A value of Stop causes non-terminating errors to be treated as terminating errors instead, immediately halting the Cmdlet’s execution. This also enables you to intercept those errors in a Try/Catch or Trap statement, as described later in this section.

在脚本顶部添加

$ErrorActionPreference = "Stop"

希望对您有所帮助。
