sendMessage

SQSClient.sendMessage(queueUrl, messageBody, options) sends a message to the specified Amazon Simple Queue Service (SQS) queue.

Parameters

Name	Type	Description
`queueUrl`	string	The URL of the Amazon SQS queue to which a message is sent. Queue URLs and names are case-sensitive.
`messageBody`	string	The message to send. The minimum size is one character. The maximum size is 256 KB.
`options`	SendMessageOptions (optional)	Options for the request.

SendMessageOptions

Name	Type	Description
`messageDeduplicationId`	string (optional)	The token used for deduplication of sent messages. This parameter applies only to FIFO (first-in-first-out) queues. If a message with a particular MessageDeduplicationId is sent successfully, any messages with the same MessageDeduplicationId are accepted but not delivered during the 5-minute deduplication interval.
`messageGroupId`	string (optional)	The tag that specifies that a message belongs to a specific message group. Messages that belong to the same message group are processed in a FIFO manner. Messages in different message groups might be processed out of order.
`messageAttributes`	object (optional)	Each message attribute consists of a `Name`, `Type`, and `Value`. For more information, see Amazon SQS Message Attributes.
`delaySeconds`	number (optional)	The length of time, in seconds, for which to delay a specific message. Valid values: 0 to 900. Maximum: 15 minutes. Messages with a positive `delaySeconds` value become available for processing after the delay period is finished. If you don’t specify a value, the default value for the queue applies.

Returns

Type	Description
`Promise<object>`	A Promise that fulfills with the message that was sent, as an object containing an `id` string property holding the unique identifier for the message, and a `bodyMD5` string property holding the MD5 digest of the non-URL-encoded message body string.

JavaScript
import exec from 'k6/execution';

import {
  AWSConfig,
  SQSClient,
} from 'https://jslib.k6.io/aws/0.13.0/sqs.js';

const awsConfig = new AWSConfig({

});

const sqs = new SQSClient(awsConfig);
const testQueue = 'https://sqs.us-east-1.amazonaws.com/000000000/test-queue';

export default async function () {
  // If our test queue does not exist, abort the execution.
  const queuesResponse = await sqs.listQueues();
  if (queuesResponse.urls.filter((q) => q === testQueue).length == 0) {
    exec.test.abort();
  }

  // Send message to test queue
  await sqs.sendMessage(testQueue, 'test', {
    messageAttributes: {
