Parsing GraphQL responses

1

Hia,

Does anyone have suggestions for parsing GraphQL formatted JSON into something I can use in a dropdown list?

I’ve so far been using REST APIs and the modeler-ui app but could learn how to add custom java to a docker container if need be?

e.g:

{
  "data": {
    "allUsers": [
      {
        "id": "ck1d2h7ug042o01789cc2p88f",
        "name": "hahahaahah"
      },
      {
      ...,
      }
    ]
  }
}

I am also interested in parsing json with flowable expression language.

Is there any example ?

My crude approach so far has been to use some simple Groovy commands in a script task:

execution.setVariable("id", response.id);
execution.setVariable("name", response.name);

where response is the result of the HTTP (REST) task saved as a process variable. This only works for boxed JSON such as:

{
    "id": ["ck1d2h7ug042o01789cc2p88f],
    "name": ["hahahaahah],
}

so doesn’t help with the GraphQL format above.

If you are using HTTP task and save the entire response as a variable then this is stored as a Jackson JsonNode. This means that in order to access the name of the first user you can try using data.allUsers[0].name (this is not tested)
