Question

在Azure PowerShell脚本中，我使用Add-AzureAccount将用户登录到Azure。但是，如何检测用户是否未成功完成登录以便我可以中止脚本？

Answer 1

另一种方法是使用try和catch块。

try {
    Add-AzureAccount -ErrorAction Stop
}

catch {
    Write-Error $_.Exception.Message
}

#Write the remaining script here
#Control won't come here unless the Add-AzureAccount was successful

Write-Verbose 'User logged in'

但是，任何Microsoft帐户都可以登录，即使他们没有任何订阅关联。所以，这里有一点修改过的代码。

try {
    $a = Add-AzureAccount -ErrorAction Stop
    if ($a.Subscriptions) {
        Write-Verbose 'User Logged in'
    } else {
        throw 'User logged in with no subscriptions'
    }
}

catch {
    Write-Error $_.Exception.Message
}

#Write the remaining script here
#Control won't come here unless the Add-AzureAccount was successful

Answer 2

不是真正的PowerShell专家（并希望我们能得到更好的答案），但我们不能做类似以下的事情：

$a = Add-AzureAccount
If ($a)
{
    Write-Verbose "User logged in"
}
Else
{
    Write-Verbose "User not logged in"
}

我使用以下功能，并且密钥使用-warningVariable，它将捕获用户是否故意取消登录屏幕，或者登录用户是否没有附加任何订阅。为了防止没有捕获到某些内容，我添加了一个errorAction stop，以便处理异常。如果用户犯了错误，下面的脚本还提供了重新输入凭据的机会。

function LoginAzure
{         

    try 
    {

        $a = Add-AzureAccount -ErrorAction Stop -WarningVariable warningAzure -ErrorVariable errorAzure


        if ($warningAzure -ne "")
        {
            $continue = Read-Host "Following warning occured: " $warningAzure " Press 'R' to re-enter credentials or any other key to stop" 
            if ($continue -eq "R")
            {
                LoginAzure 
            }
            else
            {
                exit 1
            }
        }

    } 
    catch 
    {
        $continue = Read-Host "Following error occured: " $errorAzure " Press 'R' to re-enter credentials or any other key to stop" 
        if ($continue -eq "R")
        {
            LoginAzure 
        }
        else
        {
            exit 1
        }
    }
     
}
Import-Module "C:\Program Files (x86)\Microsoft SDKs\Azure\PowerShell\ServiceManagement\Azure\Azure.psd1"

LoginAzure
