Utilizzare SendMessage con un SDK AWS o una CLI

Come inviare un messaggio

Questo esempio invia alla coda specificata un messaggio con il corpo del messaggio, il periodo di ritardo e gli attributi del messaggio specificato.

Comando:

aws sqs send-message --queue-url https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyQueue --message-body "Information about the largest city in Any Region." --delay-seconds 10 --message-attributes file://send-message.json

File di input (send-message.json):

{
  "City": {
    "DataType": "String",
    "StringValue": "Any City"
  },
  "Greeting": {
    "DataType": "Binary",
    "BinaryValue": "Hello, World!"
  },
  "Population": {
    "DataType": "Number",
    "StringValue": "1250800"
  }
}

Output:

{
  "MD5OfMessageBody": "51b0a325...39163aa0",
  "MD5OfMessageAttributes": "00484c68...59e48f06",
  "MessageId": "da68f62c-0c07-4bee-bf5f-7e856EXAMPLE"
}
