Cisco DNA-C REST API non JSON return

[wfrans]

Hi all,

I have an issue with the REST-API interface, the DNA-C returns in HTTP in stead of JSON. I already tried the header with Content-Type:application/json and Accept:application/json. Authentication/Authorization is ok, I receive a token. But this also return HTML in stead of JSON.

What am I doing wrong?

Can you share the code you are using to access the API?

I have used postman and the https://dnac/dna/apitester to learn the api.  Here is a basic access to access the device inventory and represent as json.

import requests

import json

from pprint import pprint

import sys

username = sys.argv[1]

password =  sys.argv[2]

hostname =  sys.argv[3]

login_url = 'https://{}/api/system/v1/auth/login'.format(hostname)

session = requests.session()

session.auth = username, password

session.verify = False

login_results = session.get(login_url)

session.headers.update({'cookie':login_results.headers['Set-Cookie']})

session.headers.update({'content-type':'application/json'})

devices_url = 'https://{}/api/v1/network-device'.format(hostname)

device_results = session.get(devices_url)

devices = device_results.json()

pprint(devices)

Thanks, this solved my issue, I used an incorrect URL.

The docs on https://developer.cisco.com/site/dna-center-rest-api/ state /global-credential as a path. I missed the /api/v1 part.
