Try/Catch...但想在出现错误时继续，而不是 -ErrorAction Stop

Question

在脚本编写方面，我仍然是个新手，但已经走了很长一段路。我需要在下面做一个 Try/Catch，但对此感到困惑。我展示的所有研究都显示 -ErrorAction Stop....但在这种情况下，如果有错误......继续......我认为。这是交易。脚本的这一部分检查站点是否存在，如果不存在……太棒了……继续脚本。如果确实存在，请停止并写出一些内容并在那里结束脚本。所以 TRY/CATCH 让我感到困惑。你能帮忙吗？

$URLis = "https://ourdevsite.dev.com/sites/$myVar"

add-pssnapin microsoft.sharepoint.powershell -ea 0

If (-not(Get-SPWeb $URLis)){
    Write-Host "Site does not exist, so we can proceed with building it" -foregroundcolor green
    }
Else {
Write-Host "Site does exist, so we need to pick another URL" -foregroundcolor red
}

Answer 1

您无需更改 ErrorAction，只需使用 exit 关键字即可停止脚本：

add-pssnapin microsoft.sharepoint.powershell

$URL = "https://ourdevsite.dev.com/sites/$myVar"

If (Get-SPWeb $URL) {
    Write-Host "Site does exist, so we need to pick another URL" -foregroundcolor red
    exit
}
Else {
    Write-Host "Site does not exist, so we can proceed with building it" -foregroundcolor green
}

我没有 Sharepoint 环境，所以我假设您的 Get-SPWeb 检查已经有效并且 returns true/false.
