Unable to get value of key with spaces using JsonPath library

Question

I'm using Json Path library to parse JSON. I've following json which has key with space:

{
    "attributes": {
        "First Name": "Jim",
        "Last Name": "Rohn"
    }
}

In order to get value of First Name, I wrote code like (where json is object which holds above json) -

String firstName = JsonPath.from(json).getString("attributes.First Name");

But it results into following error -

java.lang.IllegalArgumentException: Invalid JSON expression:
Script1.groovy: 1: expecting EOF, found 'Attributes' @ line 1, column 67.
   .First Name

Could you please suggest how to get values of key having spaces using json-path library?

Answer 1

Try using bracket notation for First Name as follows:

String firstName = JsonPath.from(json).getString("attributes.['First Name']");

UPDATE

Sorry for mixing different JsonPath libraries up.

If you are using com.jayway.jsonpath, try following way for escaping:

DocumentContext jsonContext = JsonPath.parse(json);
String firstName = jsonContext.read("$.attributes.['First Name']");

But if you are using ***.restassured.json-path, please use this one:

String firstName = JsonPath.from(json).getString("attributes.'First Name'");
