使用 AWS CLI 命令添加 SQS 重新驱动策略 [英] Adding SQS redrive policy using AWS CLI command

问题描述

我正在尝试使用下面的 AWS CLI 命令为 SQS 设置重新驱动策略，但看到与重新驱动 JSON 相关的错误.你能告诉我如何解决这个问题吗?

I am trying to set redrive policy for SQS using the AWS CLI Command below , but seeing an error related to redrive JSON. Can you please let me know how I can fix this?

redrive_policy="{\"RedrivePolicy\":{\"deadLetterTargetArn\":\"$dlq_arn\",\"maxReceiveCount\":\"15\"}}"

AWS CLI 命令

aws sqs set-queue-attributes --queue-url https://queue.amazonaws.com/12345678/test-queue --attributes $redrive_policy --region=us-east-1

错误信息

参数验证失败:参数类型无效Attributes.RedrivePolicy, value: OrderedDict([(u'deadLetterTargetArn',u'arn:aws:sqs:us-east-1:12345678:dlq'), (u'maxReceiveCount', u'15')]),类型:，有效类型:

推荐答案

您是否尝试过在单独的文件中创建 JSON 并将其作为参数传递给您的 AWS CLI 命令?我发现将 JSON 作为参数传递时很难让所有转义都正确.因此，您基本上可以按照 AWS 文档中的示例进行操作:

Have you tried just creating the JSON in a separate file and passing it as an argument to your AWS CLI command? I find it's difficult to get all of the escaping correct when passing the JSON as a parameter. So you'd basically do it as the example shows in the AWS documentation:

https://docs.aws.amazon.com/cli/latest/reference/sqs/set-queue-attributes.html#examples

1. 因此，首先您要创建一个名为set-queue-attributes.json"的新文件，如下所示:

    {
      "DelaySeconds": "10",
      "MaximumMessageSize": "131072",
      "MessageRetentionPeriod": "259200",
      "ReceiveMessageWaitTimeSeconds": "20",
      "RedrivePolicy": "{\"deadLetterTargetArn\":\"arn:aws:sqs:us-east-1:80398EXAMPLE:MyDeadLetterQueue\",\"maxReceiveCount\":\"1000\"}",
      "VisibilityTimeout": "60"
    }

1. 然后像这样运行命令:

aws sqs set-queue-attributes --queue-url https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyNewQueue --attributes file://set-queue-attributes.json --region=us-east-1
