To receive a message, we will use the command line with the aws sqs receive-message command; we will need to specify the --queue-url attribute to point our command at the queue.
In our example, the command to run would be this:
aws sqs receive-message
--queue-url "https://us-east-2.queue.amazonaws.com/866117724370/markocloud"
And the response would be as follows:
{
"Messages": [
{
"Body": "This is a test message
", "ReceiptHandle": "AQEBE9Pi+P5RP9FoZxgQ8xtDVT4qetd060GmD6LVr3s3iltZpAixsujI/2xEE4FqD/Mrxa4H98hSxT6Gcn2l5L0jtJRlrtVK9kl/xpjwjQqoTsEh5i9B9WWDly/QQPj6RpeL7BvfytoQ7I25DqlTHwZQMEhGgD29vJ5FzYFi8WSc7+mVozTwSOsqXM0PeoCOMnlP8UaBFniRCIVvk9HbNFE198zC+F1bDL682NfRJA7SBgRMyjaVxSauQ9hkh/5UZJElSHiYaJtEKKbYXzfosaAeHq3BNEZGQk2KV33IAnJJx1H2w7g6tODAeRF7yhVOuWAsVXfm1eSFQ46DCH9o7kAAsxEYXYO19o0uNyjMwadHA0U0CD/4inoehQAtugF2AlNEzoyTaYVLCz+ZKRVbe9wSMw==",
"MD5OfBody": "2309502dc5493f110869b570d9028942",
"MessageId": "2e50bc36-90d6-4ef9-82d2-5769462394f0"
}
]
}
The structure of the response is as follows:
- "Body": Represents the message content
- "ReceiptHandle": Is the unique identifier for the message that was received
- "MD5OfBody": The MD5 sum of the body of the message, used for delivery consistency
- "MessageId": The identifier of the message in the queue
After we have finished processing the message, we can delete the message by specifying the aws sqs delete-message command with the --queue-url and --receipt-handle options, which are required to identify the message queue and message we are deleting. In our example, this command would look like this:
aws sqs delete-message
--queue-url "https://us-east-2.queue.amazonaws.com/866117724370/markocloud"
--receipt-handle "AQEBE9Pi+P5RP9FoZxgQ8xtDVT4qetd060GmD6LVr3s3iltZpAixsujI/2xEE4FqD/Mrxa4H98hSxT6Gcn2l5L0jtJRlrtVK9kl/xpjwjQqoTsEh5i9B9WWDly/QQPj6RpeL7BvfytoQ7I25DqlTHwZQMEhGgD29vJ5FzYFi8WSc7+mVozTwSOsqXM0PeoCOMnlP8UaBFniRCIVvk9HbNFE198zC+F1bDL682NfRJA7SBgRMyjaVxSauQ9hkh/5UZJElSHiYaJtEKKbYXzfosaAeHq3BNEZGQk2KV33IAnJJx1H2w7g6tODAeRF7yhVOuWAsVXfm1eSFQ46DCH9o7kAAsxEYXYO19o0uNyjMwadHA0U0CD/4inoehQAtugF2AlNEzoyTaYVLCz+ZKRVbe9wSMw=="
The CLI command would now remove the message from the queue, and there are now no messages in the message queue.
