AWS authentication failed using HTTPS request

Question

I'm deploying CSR 1000v on an EC2 instance in AWS.

This is my python code for authentication in order to use RESTCONF which is already enabled in the router.

import requests
import pprint
from aws_requests_auth.aws_auth import AWSRequestsAuth 

def get_json(interface):

    authaws = AWSRequestsAuth(aws_access_key='AWS_ACCESS_KEY',
                       aws_secret_access_key='AWS_SECRET_ACCESS_KEY',
                       aws_host='ec2-xx-xx-xx-xx.us-west-2.compute.amazonaws.com',
                       aws_region='us-west-2',
                       aws_service='compute')

    source = 'https://ec2-xx-xx-xx-xx.us-west-2.compute.amazonaws.com/restconf/data/'
    module = 'ietf-interfaces:'
    container = 'interfaces'
    leaf = '/interface=' + interface
    options = ''

    url = source + module + container + leaf + options
    headers = {'Content-type': 'application/yang-data+json', 'Accept': 'application/yang-data+json'}

    r = requests.get(url, auth=authaws, headers=headers, verify=False)

    return r.json()

if __name__ == '__main__':

    interface = 'GigabitEthernet1'

    pprint.pprint(get_json(interface))

Here what I got after execution.

server@zsz:~/shared_files$ python get_one_interface.py 
/usr/local/lib/python2.7/dist-packages/urllib3/connectionpool.py:847: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings
  InsecureRequestWarning)
{u'errors': {u'error': [{u'error-tag': u'access-denied',
                         u'error-type': u'protocol'}]}}

Obviously, the authentication cannot be done. For aws_access_key and aws_secret_access_key, I got it from IAM console. I even generated new ones, but still does not work.

Answer 1

I have managed to find the solution.

In the router:

(config)#user any-user-name privilege 15 secret supersecretpassword

Then, it worked! Thanks to anyone who tried to help :)
