InvalidOperation：无法索引到空数组 - 在 Azure PowerShell 中从数组中获取值时

Question

我尝试使用 Azure PowerShell 代码从 azure Web 应用程序的发布配置文件中获取用户名和密码，但我在用户名获取行中收到错误”

代码：

$WebApp = Get-AzWebApp -ResourceGroupName "Practice-RG" -Name "testwebapp7298"
$publishingProfile = Get-AzWebAppPublishingProfile -WebApp $WebApp
# Create Base64 authorization header
$username = $publishingProfile.publishData.publishProfile[0].userName
$password = $publishingProfile.publishData.publishProfile[0].userPWD

结果：

PS /home/sheethal> $WebApp = Get-AzWebApp -ResourceGroupName "Practice-RG" -Name "testwebapp7298"
PS /home/sheethal> $publishingProfile = Get-AzWebAppPublishingProfile -WebApp $WebApp
PS /home/sheethal> # Create Base64 authorization header
PS /home/sheethal> $username = $publishingProfile.publishData.publishProfile[0].userName
InvalidOperation: Cannot index into a null array.
PS /home/sheethal> $password = $publishingProfile.publishData.publishProfile[0].userPWD
InvalidOperation: Cannot index into a null array.
PS /home/sheethal> $publishingProfile.publishData.publishProfile[0].userName           
InvalidOperation: Cannot index into a null array.
PS /home/sheethal> 

有人可以纠正我代码中的错误吗？

Answer 1

您可以使用

Get-AzWebAppPublishingProfile

命令编写多行代码，而不是使用

az webapp deployment list-publishing-profiles

轻松从发布配置文件中获取用户名和密码。

$userNames=az webapp deployment list-publishing-profiles --name newjan --resource-group xxxx --query '[].userName' -o tsv
$userNames
$Passwords=az webapp deployment list-publishing-profiles --name newjan --resource-group xxxx --query '[].userPWD' -o tsv
$Passwords 

输出：
