Map datatype in aws cli

I am trying to add a message to a queue in amazon aws sqs

so i tried this

root~#  aws sqs send-message --queue-url "queue/url" --message-body "message with attribute" --message-attributes '{"Name": "somename", "Type":"String", "Value":"somevalue"}'

bit it gives me this error

'unicode' object has no attribute 'keys'

but if i remove the part --message-attributes

from the command

 root~#  aws sqs send-message --queue-url "queue/url" --message-body "message with attribute"

then it works fine

http://docs.aws.amazon.com/cli/latest/reference/sqs/send-message.html

I am guessing it is the card type, how to send this parameter in card format

--message-attributes (map)

You need to pass --message-attributes (map)

data structre as{attr1 : {"DataType":"type1.option", "StringValue":val1}, attr2 : {"DataType":"typ2.option", "StringValue":val2}, ...}

So your example looks like this:

send queue



$ aws sqs send-message --queue-url "queue/url"  --message-body "message with attribute" --message-attributes '{"somename" : { "DataType":"String", "StringValue":"somevalue"}}'
{
    "MD5OfMessageBody": "ZZZZ",
    "MD5OfMessageAttributes": "YYYY",
    "MessageId": "06524772-XXXX"
}

reception queue

$ aws sqs receive-message --queue-url "queue/url" --message-attribute-names somename
{
    "Messages": [
        {
            "Body": "message with attribute",
            "ReceiptHandle": "dummy==",
            "MD5OfBody": "ZZZZ",
            "MD5OfMessageAttributes": "YYYYS",
            "MessageId": "06524772-XXXX",
            "MessageAttributes": {
                "somename": {
                    "DataType": "String",
                    "StringValue": "somevalue"
                }
            }
        }
    ]
}
