使用 PowerShell 管理服务总线资源Use PowerShell to manage Service Bus resources

2/6/2020

Azure PowerShell 是一个脚本编写环境，可用于控制和自动执行 Azure 服务的部署和管理。Azure PowerShell is a scripting environment that you can use to control and automate the deployment and management of Azure services. 本文介绍如何通过本地 Azure PowerShell 控制台或脚本，使用服务总线 Resource Manager PowerShell 模块来预配和管理服务总线实体（命名空间、队列、主题和订阅）。This article describes how to use the Service Bus Resource Manager PowerShell module to provision and manage Service Bus entities (namespaces, queues, topics, and subscriptions) using a local Azure PowerShell console or script.

还可以使用 Azure Resource Manager 模板管理服务总线实体。You can also manage Service Bus entities using Azure Resource Manager templates. 有关详细信息，请参阅使用 Azure Resource Manager 模板创建服务总线资源一文。For more information, see the article Create Service Bus resources using Azure Resource Manager templates.

备注

本文进行了更新，以便使用新的 Azure PowerShell Az 模块。This article has been updated to use the new Azure PowerShell Az module. 你仍然可以使用 AzureRM 模块，至少在 2020 年 12 月之前，它将继续接收 bug 修补程序。You can still use the AzureRM module, which will continue to receive bug fixes until at least December 2020. 若要详细了解新的 Az 模块和 AzureRM 兼容性，请参阅新 Azure Powershell Az 模块简介。To learn more about the new Az module and AzureRM compatibility, see Introducing the new Azure PowerShell Az module. 有关 Az 模块安装说明，请参阅安装 Azure PowerShell。For Az module installation instructions, see Install Azure PowerShell.

必备条件Prerequisites

在开始之前，需要符合以下先决条件：Before you begin, you'll need the following prerequisites:

Azure 订阅。An Azure subscription. 有关如何获取订阅的详细信息，请参阅[购买选项][购买选项]、[会员套餐][会员套餐]或[试用帐户][试用帐户]。For more information about obtaining a subscription, see [purchase options][purchase options], [member offers][member offers], or [trial account][trial account].
配备 Azure PowerShell 的计算机。A computer with Azure PowerShell. 有关说明，请参阅 Azure PowerShell cmdlet 入门。For instructions, see Get started with Azure PowerShell cmdlets.
大致了解 PowerShell 脚本、NuGet 包和 .NET Framework。A general understanding of PowerShell scripts, NuGet packages, and the .NET Framework.

入门Get started

第一步是使用 PowerShell 登录 Azure 帐户和 Azure 订阅。The first step is to use PowerShell to log in to your Azure account and Azure subscription. 按照 Azure PowerShell cmdlet 入门中的说明登录 Azure 帐户，检索并访问 Azure 订阅中的资源。Follow the instructions in Get started with Azure PowerShell cmdlets to log in to your Azure account, and retrieve and access the resources in your Azure subscription.

设置 Service Bus 命名空间Provision a Service Bus namespace

使用服务总线命名空间时，可以使用 Get-AzureRmServiceBusNamespace、New-AzureRmServiceBusNamespace、Remove-AzureRmServiceBusNamespace 和 Set-AzureRmServiceBusNamespace cmdlet。When working with Service Bus namespaces, you can use the Get-AzureRmServiceBusNamespace, New-AzureRmServiceBusNamespace, Remove-AzureRmServiceBusNamespace, and Set-AzureRmServiceBusNamespace cmdlets.

本示例在脚本中创建几个本地变量：$Namespace 和 $Location。This example creates a few local variables in the script; $Namespace and $Location.

$Namespace 是要使用的服务总线命名空间的名称。$Namespace is the name of the Service Bus namespace with which we want to work.
$Location 标识我们要在其中预配命名空间的数据中心。$Location identifies the data center in which we provision the namespace.
$CurrentNamespace 存储我们检索（或创建）的引用命名空间。$CurrentNamespace stores the reference namespace that we retrieve (or create).

在实际脚本中，$Namespace 和 $Location 可作为参数传递。In an actual script, $Namespace and $Location can be passed as parameters.

此部分脚本执行以下任务：This part of the script does the following:

尝试使用指定名称检索服务总线命名空间。Attempts to retrieve a Service Bus namespace with the specified name.
如果找到该命名空间，则报告它找到的内容。If the namespace is found, it reports what was found.

如果找不到该命名空间，则会创建该命名空间，并检索新创建的命名空间。If the namespace is not found, it creates the namespace and then retrieves the newly created namespace.

# Query to see if the namespace currently exists
$CurrentNamespace = Get-AzServiceBusNamespace -ResourceGroup $ResGrpName -NamespaceName $Namespace

# Check if the namespace already exists or needs to be created
if ($CurrentNamespace)
{
    Write-Host "The namespace $Namespace already exists in the $Location region:"
    # Report what was found
    Get-AzServiceBusNamespace -ResourceGroup $ResGrpName -NamespaceName $Namespace
}
else
{
    Write-Host "The $Namespace namespace does not exist."
    Write-Host "Creating the $Namespace namespace in the $Location region..."
    New-AzServiceBusNamespace -ResourceGroup $ResGrpName -NamespaceName $Namespace -Location $Location
    $CurrentNamespace = Get-AzServiceBusNamespace -ResourceGroup $ResGrpName -NamespaceName $Namespace
    Write-Host "The $Namespace namespace in Resource Group $ResGrpName in the $Location region has been successfully created."

}

创建命名空间授权规则Create a namespace authorization rule

下面的示例演示如何使用 New-AzServiceBusAuthorizationRule、Get-AzServiceBusAuthorizationRule、Set-AzServiceBusAuthorizationRule 和 Remove-AzServiceBusAuthorizationRule cmdlet 管理命名空间授权规则。The following example shows how to manage namespace authorization rules using the New-AzServiceBusAuthorizationRule, Get-AzServiceBusAuthorizationRule, Set-AzServiceBusAuthorizationRule, and Remove-AzServiceBusAuthorizationRule cmdlets.

# Query to see if rule exists
$CurrentRule = Get-AzServiceBusAuthorizationRule -ResourceGroup $ResGrpName -NamespaceName $Namespace -AuthorizationRuleName $AuthRule

# Check if the rule already exists or needs to be created
if ($CurrentRule)
{
    Write-Host "The $AuthRule rule already exists for the namespace $Namespace."
}
else
{
    Write-Host "The $AuthRule rule does not exist."
    Write-Host "Creating the $AuthRule rule for the $Namespace namespace..."
    New-AzServiceBusAuthorizationRule -ResourceGroup $ResGrpName -NamespaceName $Namespace -AuthorizationRuleName $AuthRule -Rights @("Listen","Send")
    $CurrentRule = Get-AzServiceBusAuthorizationRule -ResourceGroup $ResGrpName -NamespaceName $Namespace -AuthorizationRuleName $AuthRule
    Write-Host "The $AuthRule rule for the $Namespace namespace has been successfully created."

    Write-Host "Setting rights on the namespace"
    $authRuleObj = Get-AzServiceBusAuthorizationRule -ResourceGroup $ResGrpName -NamespaceName $Namespace -AuthorizationRuleName $AuthRule

    Write-Host "Remove Send rights"
    $authRuleObj.Rights.Remove("Send")
    Set-AzServiceBusAuthorizationRule -ResourceGroup $ResGrpName -NamespaceName $Namespace -AuthRuleObj $authRuleObj

    Write-Host "Add Send and Manage rights to the namespace"
    $authRuleObj.Rights.Add("Send")
    Set-AzServiceBusAuthorizationRule -ResourceGroup $ResGrpName -NamespaceName $Namespace -AuthRuleObj $authRuleObj
    $authRuleObj.Rights.Add("Manage")
    Set-AzServiceBusAuthorizationRule -ResourceGroup $ResGrpName -NamespaceName $Namespace -AuthRuleObj $authRuleObj

    Write-Host "Show value of primary key"
    $CurrentKey = Get-AzServiceBusKey -ResourceGroup $ResGrpName -NamespaceName $Namespace -Name $AuthRule
        
    Write-Host "Remove this authorization rule"
    Remove-AzServiceBusAuthorizationRule -ResourceGroup $ResGrpName -NamespaceName $Namespace -Name $AuthRule
}

创建队列Create a queue

若要创建队列或主题，请使用上一部分中的脚本执行命名空间检查。To create a queue or topic, perform a namespace check using the script in the previous section. 然后，创建队列：Then, create the queue:

# Check if queue already exists
$CurrentQ = Get-AzServiceBusQueue -ResourceGroup $ResGrpName -NamespaceName $Namespace -QueueName $QueueName

if($CurrentQ)
{
    Write-Host "The queue $QueueName already exists in the $Location region:"
}
else
{
    Write-Host "The $QueueName queue does not exist."
    Write-Host "Creating the $QueueName queue in the $Location region..."
    New-AzServiceBusQueue -ResourceGroup $ResGrpName -NamespaceName $Namespace -QueueName $QueueName -EnablePartitioning $True
    $CurrentQ = Get-AzServiceBusQueue -ResourceGroup $ResGrpName -NamespaceName $Namespace -QueueName $QueueName
    Write-Host "The $QueueName queue in Resource Group $ResGrpName in the $Location region has been successfully created."
}

修改队列属性Modify queue properties

执行上一部分中的脚本后，可以使用 Set-AzServiceBusQueue cmdlet 更新队列的属性，如以下示例所示：After executing the script in the preceding section, you can use the Set-AzServiceBusQueue cmdlet to update the properties of a queue, as in the following example:

$CurrentQ.DeadLetteringOnMessageExpiration = $True
$CurrentQ.MaxDeliveryCount = 7
$CurrentQ.MaxSizeInMegabytes = 2048
$CurrentQ.EnableExpress = $True

Set-AzServiceBusQueue -ResourceGroup $ResGrpName -NamespaceName $Namespace -QueueName $QueueName -QueueObj $CurrentQ

设置其他 Service Bus 实体Provisioning other Service Bus entities

可以使用服务总线 PowerShell 模块预配其他实体，例如主题和订阅。You can use the Service Bus PowerShell module to provision other entities, such as topics and subscriptions. 这些 cmdlet 在语法上与上一部分所示的队列创建 cmdlet 类似。These cmdlets are syntactically similar to the queue creation cmdlets demonstrated in the previous section.
