JsonParseException : Illegal unquoted character ((CTRL-CHAR, code 10)

Question

I\'m trying to use org.apache.httpcomponents to consume a Rest API, which will post JSON format data to API.

I get this exception:

Answer 1

This can happen if you have a newline (or other control character) in a JSON string literal.

{"foo": "bar
baz"}

If you are the one producing the data, replace actual newlines with escaped ones "\\n" when creating your string literals.

{"foo": "bar\nbaz"}
