Getting JSON fields in Freemarker

Hi,

 

I have code that retrieves a JSON object with the following structure and stores it in a variable named response_getUser:

 

{
   "user": {
      "id": 123
   }
}

However, I am unable to access the id using the following code

 

response_getUser.content.user.get("id")

I keep receiving this a null error for the code.

 

Is there any help on how to debug this? I am new to using freemarker and it has been really difficult to figure out what the variables are in lithium.

    you should be able to do one of theses two (I'm afk, or would have tested it first):

    <#assign respons_getUser = { "user": { "id": 123 } } />
    ${user.id}

    OR:

    <#assign response_getUser = "{ "user": { "id": 123 } }"?eval />
    ${user.id}

    I'd recommend the first way over the second, as using eval can be dangerous - you need to be careful to avoid freemarker injection attacks.
