Question

我有一个脚本可以创建新的AD对象（通过New-ADObject，因为它发生）。如果对象已经存在，我需要抓住并处理它。但是，异常类型并不像FullyQualifiedErrorId那样明确。请注意以下内容：

> $Error[-1] | Format-List -Property * -Force

writeErrorStream      : True
PSMessageDetails      : 
Exception             : Microsoft.ActiveDirectory.Management.ADException: An attempt was made to add an object to the directory with 
                    a name that is already in use ---> System.ServiceModel.FaultException: The supplied entry already exists.

如何在Catch块中使用更详细的信息？

Answer 1

FullyQualifiedErrorId只是异常对象的.Message属性以及发生异常的类的完全限定名称。

您无法通过FullyQualifiedErrorId捕获，但您可以通过异常类型捕获：

try {
    # Do something that causes the 'name already in use' exception you're getting.
} catch [System.ActiveDirectory.Management.ADException] {
    if ($_.Exception.Message -ilike "*already in use") {
        # Do something to handle the error condition.
    }
}

请注意，这不是跨不同语言的可移植解决方案，因为异常消息可能位于非英语版本的Windows上。

此外，您可能需要修改try块以包含-ErrorAction Stop以确保捕获错误。

Answer 2

如果New-ADObject引发的错误不是使用catch的终止错误将无济于事。您可以做的一件事是使用ErrorAction参数使错误成为终止错误：

try{
   New-ADObject ... -ErrorAction Stop
}
catch{
   ... handle the error ....
}

Answer 3

我不知道您是否可以通过FullyQualifiedErrorId捕获异常，但是我找到了这种方法来获取它，并且对我有用：

$InerrMessage= $_.FullyQualifiedErrorId

如何通过PowerShell中的FullyQualifiedErrorId捕获？
