CLI

AWS CLI

若要取得佇列的屬性

此範例會取得所有指定佇列的屬性。

命令：


aws sqs get-queue-attributes --queue-url https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyQueue --attribute-names All

輸出：


{
  "Attributes": {
    "ApproximateNumberOfMessagesNotVisible": "0",
    "RedrivePolicy": "{\"deadLetterTargetArn\":\"arn:aws:sqs:us-east-1:80398EXAMPLE:MyDeadLetterQueue\",\"maxReceiveCount\":1000}",
    "MessageRetentionPeriod": "345600",
    "ApproximateNumberOfMessagesDelayed": "0",
    "MaximumMessageSize": "262144",
    "CreatedTimestamp": "1442426968",
    "ApproximateNumberOfMessages": "0",
    "ReceiveMessageWaitTimeSeconds": "0",
    "DelaySeconds": "0",
    "VisibilityTimeout": "30",
    "LastModifiedTimestamp": "1442426968",
    "QueueArn": "arn:aws:sqs:us-east-1:80398EXAMPLE:MyNewQueue"
  }
}

此範例只會取得指定佇列的最大訊息大小和可見性逾時屬性。

命令：


aws sqs get-queue-attributes --queue-url https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyNewQueue --attribute-names MaximumMessageSize VisibilityTimeout

輸出：


{
  "Attributes": {
    "VisibilityTimeout": "30",
    "MaximumMessageSize": "262144"
  }
}
