Amazon SQS、Amazon SNS 与 Tools for Windows PowerShell

本节提供演示如何执行以下操作的示例：

创建 Amazon SQS 队列并获取队列 ARN

以下命令在您的默认区域中创建 SQS 队列。输出会显示新队列的 URL。

PS > New-SQSQueue -QueueName myQueue
https://sqs.us-west-2.amazonaws.com/123456789012/myQueue 

以下命令检索队列的 ARN。

PS > Get-SQSQueueAttribute -QueueUrl https://sqs.us-west-2.amazonaws.com/123456789012/myQueue -AttributeName QueueArn
...
QueueARN               : arn:aws:sqs:us-west-2:123456789012:myQueue
...

创建 Amazon SNS 主题

以下命令在您的默认区域中创建 SNS 主题，并返回新主题的 ARN。

PS > New-SNSTopic -Name myTopic
arn:aws:sns:us-west-2:123456789012:myTopic

向 SNS 主题授予权限

下面的示例脚本创建一个 SQS 队列和一个 SNS 主题，并授予对 SNS 主题的权限，以便它可以将消息发送到 SQS 队列：

# create the queue and topic to be associated
$qurl = New-SQSQueue -QueueName "myQueue"
$topicarn = New-SNSTopic -Name "myTopic"

# get the queue ARN to inject into the policy; it will be returned
# in the output's QueueARN member but we need to put it into a variable
# so text expansion in the policy string takes effect
$qarn = (Get-SQSQueueAttribute -QueueUrl $qurl -AttributeNames "QueueArn").QueueARN

# construct the policy and inject arns
$policy = @"
{
    "Version": "2012-10-17",
    "Statement": {
        "Effect": "Allow",
        "Principal": "*",
        "Action": "SQS:SendMessage",
        "Resource": "$qarn",
        "Condition": { "ArnEquals": { "aws:SourceArn": "$topicarn" } }
    }
}
"@

# set the policy
Set-SQSQueueAttribute -QueueUrl $qurl -Attribute @{ Policy=$policy }

为队列订阅 SNS 主题

以下命令将队列 myQueue 订阅到 SNS 主题 myTopic，并返回订阅 ID：

PS > Connect-SNSNotification `
    -TopicARN arn:aws:sns:us-west-2:123456789012:myTopic `
    -Protocol SQS `
    -Endpoint arn:aws:sqs:us-west-2:123456789012:myQueue
arn:aws:sns:us-west-2:123456789012:myTopic:f8ff77c6-e719-4d70-8e5c-a54d41feb754

授予权限

以下命令授予对主题 sns:Publish 执行 myTopic 操作的权限。

PS > Add-SNSPermission `
    -TopicArn arn:aws:sns:us-west-2:123456789012:myTopic `
    -Label ps-cmdlet-topic `
    -AWSAccountIds 123456789012 `
    -ActionNames publish

以下命令授予对队列 sqs:ReceiveMessage 执行 sqs:DeleteMessage 和 myQueue 操作的权限。

PS > Add-SQSPermission `
    -QueueUrl https://sqs.us-west-2.amazonaws.com/123456789012/myQueue `
    -AWSAccountId "123456789012" `
    -Label queue-permission `
    -ActionName SendMessage, ReceiveMessage

验证结果

以下命令通过向 SNS 主题 myTopic 发布消息来测试新队列和主题，并返回 MessageId。

PS > Publish-SNSMessage `
    -TopicArn arn:aws:sns:us-west-2:123456789012:myTopic `
    -Message "Have A Nice Day!"
728180b6-f62b-49d5-b4d3-3824bb2e77f4

以下命令从 SQS 队列 myQueue 检索消息并显示此消息。

PS > Receive-SQSMessage -QueueUrl https://sqs.us-west-2.amazonaws.com/123456789012/myQueue
