[Mrinmay_Biswas]

I have python script is is working using python request and response but same  body and credential is not working in groovy with curl command. It is sowing null event pointer while trying to update calendar using event.json

Python scripts which is working- 

import requests
import json
baseURL = 'https://confluence.mycomp.com/rest/calendar-services/1.0/calendar/events.json'
headers = { "content-type" : "application/x-www-form-urlencoded" }
user='****'
password='****'
hd={'Content-Type': 'application/json'}
calenderData = {"subCalendarId":"7ed3840a-6e3e-4043-a4da-be02a8208eaf","eventType":"Events", "what":"CTEF1 Test Deployment", "person": ["2c9fad3f6764e43f0167788e66a9004e"],"startDate":"28-Apr-2020","endDate": "28-Apr-2020","allDayEvent": "true","where": "By DVM PipeLine" }
response = requests.put(baseURL, headers=headers, auth=(user, password), data=calenderData, timeout=15)#curl -u s-osj_jira-u-itsehbg:wnesIl16 --data datac -H "Content-Type: application/json" -X PUT https://confluence.build.ingka.ikea.com/rest/calendar-services/1.0/calendar/events.json
print('\n\n\n')
print(response.content)

Groovy curls which is not working :-

baseURL = 'https://confluence.mycomp.com/rest/calendar-services/1.0/calendar/events.json'

user='****'
password='****'

calenderData = {"subCalendarId":"7ed3840a-6e3e-4043-a4da-be02a8208eaf","eventType":"Events", "what":"CTEF1 Test Deployment", "person": ["2c9fad3f6764e43f0167788e66a9004e"],"startDate":"28-Apr-2020","endDate": "28-Apr-2020","allDayEvent": "true","where": "By DVM PipeLine" }

def response = ["curl", "-k", "-u", "user:passwords", "-X", "PUT", "-d", "${calenderData}", "-H", "Content-Type:application/json", "${baseURL}"].execute().text
