To retrieve a list of hosts using the Cisco DNA Center API, the provided Python script needs to be completed with the appropriate code snippets. Here's how the final script looks:

import json, requests, urllib3

from requests.auth import HTTPBasicAuth

from config import host, username, password

headers = { 'Content-Type': "application/json", 'x-auth-token': "csd0934rjxx" }

def dna_api_auth(host, username, password):

url = "https://{}/dna/system/api/v1/auth/token ".format(host)

response = requests.post(url, auth=HTTPBasicAuth(username, password), headers=headers, verify=False)

token = response.json()["Token"]

return token

def list_dna_devices(token):

url = "https://{}/dna/intent/api/v1/network-device ".format(host)

headers["x-auth-token"] = token

response = requests.get(url, headers=headers, verify=False)

data = response.json()

for item in data['response']:

print(item["hostname"])

token = dna_api_auth(host, username, password)

list_dna_devices(token)

application/json: This is used to set the content type for the headers.

token = response.json()["Token"]: This extracts the authentication token from the response.

data['response']: This accesses the 'response' part of the JSON data returned by the API.

token: This passes the token to the headers for authorization.

json(): This parses the response to JSON format.

for item in data['response']: This loops through each item in the response data.

hostname: This prints the hostname of each device.

When configuring a Cisco IOS XE networking device using RESTCONF, the default data encoding method is application/yang-data+json. This MIME type indicates that the data is encoded in JSON format and structured according to YANG data models. YANG (Yet Another Next Generation) is a data modeling language used to model configuration and state data manipulated by the NETCONF protocol, which RESTCONF leverages.
