Question

我有一个包含一些错误处理的Azure功能（PowerShell）。如果出现错误，我会执行几个简单的操作，然后我希望停止执行，但这不起作用; PowerShell忽略了exit 1命令并继续执行。

try{
    $metrics = Get-AzureMetrics -BearerToken $bearer_token -SubscriptionId $env:HC_SubscriptionId -ResourceGroup $env:HC_ResourceGroup -ResourceType $env:HC_ResourceType -ResourceName $env:HC_ResourceName
} catch {
    $failure = $_.Exception.Message
    Write-Output "[ERROR] Failed to GET metrics from Azure Monitor. $failure"
    Invoke-LogToSplunk -EventHost "bvt-processevnts" -Source $env:HealthCheckFunctionName -Message "Failed to GET metrics from Azure Monitor. $failure" -Severity "ERROR" -SplunkUri $env:SplunkUrl -AccessToken $env:SplunkToken | Out-Null
    exit 1
}

请注意，exit 1在本地测试时有效，只有在我将其作为Azure功能运行时才能看到此问题。我还试过了Return和Break，但这些命令也被忽略了。

我考虑用exit 1替换$error_occurred = $true，然后在if语句中嵌套进行命令（见下文）。但是，如果可能的话，我希望避免这种情况，因为从长远来看管理起来比较困难，而团队中可能需要查看/编辑Azure功能的其他人则不太清楚。< / p>

if ( ! ( $error_occurred ) ) {
    # Other commands
}

所以我的问题（希望）很简单;如何告诉Azure功能停止执行？

此解决方案可能不符合您的需求，但您可以尝试这样的事情吗？

Function Get-AzureMetricsOrFail ($bearer_token) {
    try{
        $metrics = Get-AzureMetrics -BearerToken $bearer_token -SubscriptionId $env:HC_SubscriptionId -ResourceGroup $env:HC_ResourceGroup -ResourceType $env:HC_ResourceType -ResourceName $env:HC_ResourceName
    } catch {
        $failure = $_.Exception.Message
        Write-Output "[ERROR] Failed to GET metrics from Azure Monitor. $failure"
        Invoke-LogToSplunk -EventHost "bvt-processevnts" -Source $env:HealthCheckFunctionName -Message "Failed to GET metrics from Azure Monitor. $failure" -Severity "ERROR" -SplunkUri $env:SplunkUrl -AccessToken $env:SplunkToken | Out-Null
    }
    return $metrics
}

$metrics_result = Get-AzureMetricsOrFail -bearer_token 'some_token'

if($metrics_result) {
    'Successfully obtained Azure Metrics'
    # Rest of code
} else {
    'Failed getting Azure Metrics.'
}

或者，也许只想移动Exit语句？

try{
    $metrics = Get-AzureMetrics -BearerToken $bearer_token -SubscriptionId $env:HC_SubscriptionId -ResourceGroup $env:HC_ResourceGroup -ResourceType $env:HC_ResourceType -ResourceName $env:HC_ResourceName
} catch {
    $failure = $_.Exception.Message
    Write-Output "[ERROR] Failed to GET metrics from Azure Monitor. $failure"
    Invoke-LogToSplunk -EventHost "bvt-processevnts" -Source $env:HealthCheckFunctionName -Message "Failed to GET metrics from Azure Monitor. $failure" -Severity "ERROR" -SplunkUri $env:SplunkUrl -AccessToken $env:SplunkToken | Out-Null
}
if(!($metrics)) {
    exit
}

Azure函数执行忽略＆＃39;退出＆＃39;命令
