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

Microsoft 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。Microsoft 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

本文已经过更新，以便使用 Azure Az PowerShell 模块。This article has been updated to use the Azure Az PowerShell module. 若要与 Azure 交互，建议使用的 PowerShell 模块是 Az PowerShell 模块。The Az PowerShell module is the recommended PowerShell module for interacting with Azure. 若要开始使用 Az PowerShell 模块，请参阅安装 Azure PowerShell。To get started with the Az PowerShell module, see Install Azure PowerShell. 若要了解如何迁移到 Az PowerShell 模块，请参阅 将 Azure PowerShell 从 AzureRM 迁移到 Az。To learn how to migrate to the Az PowerShell module, see Migrate Azure PowerShell from AzureRM to Az.

先决条件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:

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-AzServiceBusNamespace、New-AzServiceBusNamespace、Remove-AzServiceBusNamespace 和 Set-AzServiceBusNamespace cmdlet。When working with Service Bus namespaces, you can use the Get-AzServiceBusNamespace, New-AzServiceBusNamespace, Remove-AzServiceBusNamespace, and Set-AzServiceBusNamespace 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:

  1. 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.

  2. 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.

  3. 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.
