Handle error HTTPBuilder groovy

[Ryker Tyler]

I have this code snippet which will call an API and return a list of Users in List format:

return http.request(Method.GET, ContentType.JSON) {
    uri.path = USERS_ENDPOINT
} as List<Map>

That example will work perfectly if there is no problem with the API. Now I want to handle the case where this API returns an error (such as 401, 500):

• If the API call is successful, return the data as List<Map> immediately
• If there is any problem, do something and go to the next line

I have tried this but it does not work:

http.request(Method.GET, ContentType.JSON) {
    uri.path = USERS_ENDPOINT

    response.success { res, reader ->
        return reader as List<Map>
    }

    response.failed {
        // do somthing here, a logging for example
        log.warn "Failed"
    }
}

// the next statement I want to execute after the API call has been failed

 Any idea on this?

Hi Ryker,

You can try something like below:

def http = new HTTPBuilder('http://localhost:XXXX/rest/scriptrunner/latest/custom/getCurrentUser')
def test = http.request(Method.GET, ContentType.JSON) {
   uri.path = "/rest/scriptrunner/latest/custom/getCurrentUser"

   response.success = { res, reader ->
      //return reader as List<Map>
      log.warn("Success!" )
   }

   response.failure = { resp, reader ->
      // do somthing here, a logging for example
      log.warn("Failed!" )
   }
}

return test
