AWS SNS how to add line breaks in message

Question

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

aws sns publish --cli-input-json \"{\\\"TopicArn\\\":\\\"xxx\\\",\\\"Message\\\":\\\"first line\\n          


        

Answer 1

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.

Answer 2

four backslash works for me

using Aws SNS with Firebase

EX: backslashbackslashbackslashbackslash+n

Answer 3

This worked out for me:

"first line
second line"

Answer 4

aws sns publish --topic-arn "arn:aws:sns:us-west-2:0123456789012:my-topic" --message file://message.txt

message.txt is a text file containing the message to publish:

Hello World Second Line

Putting the message in a text file allows you to include line breaks .
