您可以使用Azure PowerShell.这是适合您的PowerShell脚本.

You can use Azure PowerShell. Here is a PowerShell Script for you.

try{
    $acct = Get-AzureRmSubscription
}
catch{
    Login-AzureRmAccount
}

$myResourceGroup = '<your resource group>'
$mySite = '<your web app>'
$myResourceGroup2 = '<another resource group>'
$mySite2 = '<another web app>'

$props = (Invoke-AzureRmResourceAction -ResourceGroupName $myResourceGroup `
        -ResourceType Microsoft.Web/sites/Config -Name $mySite/appsettings `
        -Action list -ApiVersion 2015-08-01 -Force).Properties

$hash = @{}
$props | Get-Member -MemberType NoteProperty | % { $hash[$_.Name] = $props.($_.Name) }

Set-AzureRMWebApp -ResourceGroupName $myResourceGroup2 `
        -Name $mySite2 -AppSettings $hash

此脚本将应用程序设置从$mySite复制到$mySite2.如果您的Web应用程序涉及插槽，则对于$props，您应该改用以下命令.

This script copy app settings from $mySite to $mySite2. If your web app involves with slot, for $props, you should use the following command instead.

$props = (Invoke-AzureRmResourceAction -ResourceGroupName $myResourceGroup `
        -ResourceType Microsoft.Web/sites/slots/Config -Name $mySite/$slot/appsettings `
        -Action list -ApiVersion 2015-08-01 -Force).Properties 

然后，使用Set-AzureRMWebAppSlot代替Set-AzureRMWebApp

Set-AzureRMWebAppSlot -ResourceGroupName $myResourceGroup2 `
        -Name $mySite2 -Slot $slot -AppSettings $hash
