Use SendMessageBatch com um AWS SDK ou CLI

Os exemplos de códigos a seguir mostram como usar SendMessageBatch.

Exemplos de ações são trechos de código de programas maiores e devem ser executados em contexto. É possível ver essa ação no contexto no seguinte exemplo de código:

• Enviar e receber lotes de mensagens

CLI

AWS CLI

Como enviar várias mensagens como um lote

Este exemplo envia duas mensagens com os corpos da mensagem, os períodos de atraso e os atributos de mensagem especificados para a fila especificada.

Comando:

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