How to POST to a Rest API using Scriptrunner

Chris Shepherd

Hi folks,

I'm trying to post to a rest api using scriptrunner:

import groovyx.net.http.HTTPBuilder
import static groovyx.net.http.ContentType.*
import static groovyx.net.http.Method.*
import org.apache.log4j.Logger
import org.apache.log4j.Level

def log = Logger.getLogger("com.acme.CreateSubtask")
log.setLevel(Level.DEBUG)

def http = new HTTPBuilder('https://serviceportal.pornhub.local:443/') 
def body = '{"parameters": [ { "value": { "string": { "value": "testu" } }, "type": "string", "name": "username", "scope": "local" }]}'

try
{
http.request( POST, JSON ) {req ->
uri.path = 'vco/api/workflows/34c1dc35-1d56-40ec-8741-18fb6ed0d59e/executions/'
body = body

response.success = { resp ->
println "POST response status: ${resp.statusLine}"
assert resp.statusLine.statusCode == 201
}
}
}
catch (groovyx.net.http.HttpResponseException ex) {
log.debug ex.printStackTrace()
log.debug ex.toString()
}

 

The call works fine in postman but all i get when i run this through the script console is a groovyx.net.http.HttpResponseException with no details as to what I am doing wrong.  Can anyone point out what I am doing wrong?

thanks

Hi Chris,

First off I'd start with configuring proper handlers for your HttpBuilder. That way you you'll always be able to see what is wrong instead of simply getting an exeption thrown at your face.

I wrote this simple method to create an instance of HttpBuild with all handlers configured:

import groovyx.net.http.HTTPBuilder

HTTPBuilder getHttpBuilder(String url) {
    HTTPBuilder http = new HTTPBuilder(url)
    http.setHeaders(["X-Atlassian-Token": "no-check"])
    http.getHandler().failure = { respObject, body ->
        [response: respObject, body: body]
    }
    http.getHandler().success = { respObject, body ->
        [response: respObject, body: body]
    }
return http
}

Just don't forget to add Authorization header to it.

Now that we have it out of the way I think I found what's wrong with your code. Your request body is a string while is should actually be a JSON. Here's how you fix it:

 

import groovy.json.JsonOutput

def body = JsonOutput.toJson(["parameters": [ { "value": { "string": { "value": "testu" } }, "type": "string", "name": "username", "scope": "local" }]])

Hope this helps
