批量删除多条消息
此示例将删除指定消息。
命令:
aws sqs delete-message-batch --queue-url
https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyQueue
--entriesfile://delete-message-batch.json
输入文件 (delete-message-batch.json):
[ { "Id": "FirstMessage", "ReceiptHandle": "AQEB1mgl...Z4GuLw==" }, { "Id": "SecondMessage", "ReceiptHandle": "AQEBLsYM...VQubAA==" } ]
输出:
{ "Successful": [ { "Id": "FirstMessage" }, { "Id": "SecondMessage" } ] }
