AWS - Read SQS Message via Lambda - amazon-web-services

Question

Below code is copied from AWS documentation, but my code is almost the same except for the queue URL definition part.
I want to print out the message body in JSON format, but it seems it has some things extra. How can I get rid of them without using substring?
# Create SQS client
# blah blah
# Receive message from SQS queue
response = sqs.receive_message(
QueueUrl=queue_url,
AttributeNames=[
'SentTimestamp'
],
MaxNumberOfMessages=1,
MessageAttributeNames=[
'All'
],
VisibilityTimeout=0,
WaitTimeSeconds=0
)
message = response['Messages'][0]
receipt_handle = message['ReceiptHandle']
print('Received and deleted message: %s' % message)
This printed message has following format:
START RequestId: fe107bc8-3829-4600-9bfc-df89f59b0c70 Version: $LATEST
{JSON body}
END RequestId: fe107bc8-3829-4600-9bfc-df89f59b0c70
REPORT RequestId: fe107bc8-3829-4600-9bfc-df89f59b0c70 Duration: 914.38 ms Billed Duration: 1000 ms Memory Size: 128 MB Max Memory Used: 71 MB Init Duration: 247.03 ms
What I really want is just the {JSON body}. How can I get rid of the rest?

Answer 1

Unfortunately you can't remove
START RequestId: fe107bc8-3829-4600-9bfc-df89f59b0c70 Version: $LATEST
END RequestId: fe107bc8-3829-4600-9bfc-df89f59b0c70
REPORT RequestId: fe107bc8-3829-4600-9bfc-df89f59b0c70 Duration: 914.38 ms Billed Duration: 1000 ms Memory Size: 128 MB Max Memory Used: 71 MB Init Duration: 247.03 ms
from the CloudWatch Logs. This is standard print out behavior for a lambda function.
However, you can use log event filters in console which can help with locating specific {JSON body} of interest. It is the most basic and fastest to solution to use though.
More complex filtering of your logs is also possible, but I think this is not what you are after.
