AWS SNS how to add line breaks in message

I'm trying to send SNS messages via CLI in json format. 

aws sns publish --cli-input-json "{\"TopicArn\":\"xxx\",\"Message\":\"first line\n second line\",\"Subject\":\"Empty subject\"}"

But the \n doesn't work. Neither is "\r\n" or "\n". I think the string is escaped by SNS so \n doesn't work. Does anyone know how to send a message of 2 lines?(Sending 2 messages is not an option) Appreciate your advice!

Solution

  • I think \\n is actually what you are looking for. I've just tested it by sending push notifications to my device through AWS SNS.

    So your message should look like this:

    aws sns publish --cli-input-json "{\"TopicArn\":\"xxx\",\"Message\":\"first line\\nsecond line\",\"Subject\":\"Empty subject\"}"

    Note, you should not leave the white space after the line break symbol, otherwise, your new line would start with that space.
