Scriptrunner HTTP Requests and Brackets

[Andrew Lipscomb]

So if we look at one of the out-of-box scripts for ScriptRunner Cloud

post('/rest/api/2/issue')
        .header('Content-Type', 'application/json')
        .body(
        [
                fields: [
                        summary    : 'Task Summary',
                        description: "Don't forget to do this!.",
                        project    : [
                                key: projectKey
                        ],
                        issuetype  : [
                                id: taskType
                        ]
                ]
        ])

We see that the JSON brackets that would normally be a curly bracket are now a square bracket.

I can't find any standards or documentation around this, so hopefully someone knows:

a) Why a non-standard syntax is used and 

b) How to then show arrays in JSON (where a square bracket would be used normally)

//Rough Custom field array representation; how is this done in Groovy?
customfield_12345: [
	{
		name: "Johnny"
		asset: "Subaru"
	}
	{
		name: "Kate"
		asset: "Holden"
	}
]

Hi Andrew,

The script uses Groovy map and list notation, which gets converted into JSON rather than JSON directly. 

Your example would be:

customfield_12345: [ // start array
  [ //start object
    name : "Johnny",
    asset: "Subaru"
  ],
  [
    name : "Kate",
    asset: "Holden"
 ]
]

Note that map literals are defined as [key: value] pairs and lists use comma separated lists.

It is possible to use JSON directly (although much less convenient) like so:

post('/rest/api/2/issue')
        .header('Content-Type', 'application/json')
        .body("""
        {
                "fields": {
                        "summary"    : "Task Summary",
                        "description": "Don't forget to do this!.",
                        "project"    : {
                                "key": "${projectKey}"
                        },
                        "issuetype"  : {
                                "id": "${taskType}"
                        }
                }
        }
        """).asString()
