or GET /idf/<job_ID>/<case_name>/<file name>/<type_name>/<obj_id> for a jEPlus project

Example using curl://

Send the /idf command using curl to retrieve the first People object:

curl -b cookies https://api.ensims.com/jess_web/api/idf/12251/in.idf/People/0

Or if it is a jEPlus project,

curl -b cookies https://api.ensims.com/jess_web/api/idf/12264/EP_0-T_0-W_0-P1_5-P2_0-P3_0-P4_0/in.idf/People/0

To retrieve all People objects in the IDF model:

curl -b cookies https://api.ensims.com/jess_web/api/idf/12251/in.idf/People/-1

On success, the IDF object(s) will be returned in a JSON object. If the requested file does not exist, an HTTP 404 Not Found error will be returned. If the job is not accessible to the current user, or the existing JWT is invalid, an HTTP 401 Unauthorized code will be returned.

Example using Python Requests

Make sure Requests is correctly installed in your Python environment, and run the following lines:

import requests

# Existing cookies are expected to be stored in the variable 'cookies'
r = requests.get('https://api.ensims.com/jess_web/api/idf/12251/in.idf/People/0', cookies=cookies)

# Or, if it is a jEPlus project
r = requests.get('https://api.ensims.com/jess_web/api/idf/12264/EP_0-T_0-W_0-P1_5-P2_0-P3_0-P4_0/in.idf/People/0', cookies=cookies)

# Show returned object  
r.json()
