Replacing Http-Connector with Jsoup usage

Camunda 7 Topics Discussion & Questions

Here is another interesting use case where you could use Jsoup + variablesInResult parameter of the /start process-definition endpoint to provide a validations workflow.

Example: you submit a form, and you need to have server side validations with other systems.

Could also be 4 sequential scripts. The performance was the same.

So your setup would look something like:

function-internal
function-internal1223×638 55.4 KB

function-external
function-external1216×674 56 KB

postman-request
postman-request1090×355 34.1 KB

postman-response
postman-response1148×698 67.1 KB

The function.js looks like this:

if (execution.hasVariable('valueToValidate')){
  var valueToValidate = execution.getVariable('valueToValidate')
} else {
  throw 'valueToValidate variable does not exist'
}

with (new JavaImporter(org.jsoup))
{
  var doc = Jsoup.connect('http://ip.jsontest.com')
                  .method(Java.type('org.jsoup.Connection.Method').GET)
                  .header('Accept', 'application/json')
                  .data('filterABC', valueToValidate)
                  .timeout(5000)
                  .ignoreContentType(true)
                  .execute()

  var resBody = doc.body()
}

function spinify(body)
{
  var parsed = JSON.parse(body)
  var stringified = JSON.stringify(parsed)
  var spin = S(stringified)
  return spin
}

execution.setVariable('response', spinify(resBody))
// execution.setVariable('response', resBody)

The performance was about the same for returning a SPIN json object vs a string.
