CLI

AWS CLI

Untuk menghapus beberapa pesan sebagai batch

Contoh ini menghapus pesan yang ditentukan.

Perintah:

aws sqs delete-message-batch --queue-url https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyQueue --entries file://delete-message-batch.json

Berkas masukan (delete-message-batch.json):

[
  {
        "Id": "FirstMessage",
        "ReceiptHandle": "AQEB1mgl...Z4GuLw=="
  },
  {
    "Id": "SecondMessage",
        "ReceiptHandle": "AQEBLsYM...VQubAA=="
  }
]

Output:

{
  "Successful": [
    {
      "Id": "FirstMessage"
    },
    {
      "Id": "SecondMessage"
    }
  ]
}
