与 AWS SDK或DeleteMessage一起使用 CLI

从 Amazon SQS 队列接收消息，然后删除该消息。

删除消息

此示例将删除指定消息。

命令:

aws sqs delete-message --queue-url https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyQueue --receipt-handle AQEBRXTo...q2doVA==

输出：

None.

        try {
            for (Message message : messages) {
                DeleteMessageRequest deleteMessageRequest = DeleteMessageRequest.builder()
                        .queueUrl(queueUrl)
                        .receiptHandle(message.receiptHandle())
                        .build();
                sqsClient.deleteMessage(deleteMessageRequest);
            }
        } catch (SqsException e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }

接收和删除 Amazon SQS 消息。

  ReceiveMessageCommand,
  DeleteMessageCommand,
  SQSClient,
  DeleteMessageBatchCommand,
} from "@aws-sdk/client-sqs";

const client = new SQSClient({});

const receiveMessage = (queueUrl) =>
  client.send(
    new ReceiveMessageCommand({
      AttributeNames: ["SentTimestamp"],
      MaxNumberOfMessages: 10,
      MessageAttributeNames: ["All"],
      QueueUrl: queueUrl,
      WaitTimeSeconds: 20,
      VisibilityTimeout: 20,
    }),
  );

export const main = async (queueUrl = SQS_QUEUE_URL) => {
  const { Messages } = await receiveMessage(queueUrl);

  if (!Messages) {
    return;
  }

  if (Messages.length === 1) {
    console.log(Messages[0].Body);
    await client.send(
      new DeleteMessageCommand({
        QueueUrl: queueUrl,
        ReceiptHandle: Messages[0].ReceiptHandle,
      }),
    );
  } else {
    await client.send(
      new DeleteMessageBatchCommand({
        QueueUrl: queueUrl,
        Entries: Messages.map((message) => ({
          Id: message.MessageId,
          ReceiptHandle: message.ReceiptHandle,
        })),
      }),
    );
  }
};

接收和删除 Amazon SQS 消息。

var AWS = require("aws-sdk");
// Set the region
AWS.config.update({ region: "REGION" });

// Create an SQS service object
var sqs = new AWS.SQS({ apiVersion: "2012-11-05" });

var queueURL = "SQS_QUEUE_URL";

      } else {

  }

    println("Delete Messages from $queueUrlVal")

    val purgeRequest =
        PurgeQueueRequest {
            queueUrl = queueUrlVal
        }

    SqsClient { region = "us-east-1" }.use { sqsClient ->
