MAAS API utilises 0-legged OAuth for authentication. While some endpoints allow anonymous access, others require authenticated requests. This page provides examples in Python, Ruby, curl, and HTTP for fetching the list of nodes.
Python
The example employs the fades library, but you can also use requests_oauthlib and oauthlib. Replace <MAAS_SERVER_IP> and <API-KEY> with appropriate values.
from oauthlib.oauth1 import SIGNATURE_PLAINTEXT
from requests_oauthlib import OAuth1Session
MAAS_HOST = "http://<MAAS_SERVER_IP>:5240/MAAS"
CONSUMER_KEY, CONSUMER_TOKEN, SECRET = "<API-KEY>".split(":")
maas = OAuth1Session(CONSUMER_KEY, resource_owner_key=CONSUMER_TOKEN, resource_owner_secret=SECRET, signature_method=SIGNATURE_PLAINTEXT)
nodes = maas.get(f"{MAAS_HOST}/api/2.0/machines/", params={"op": "list_allocated"})
nodes.raise_for_status()
print(nodes.json())
Ruby
require 'oauth'
require 'oauth/signature/plaintext'
def perform_API_request(site, uri, key, secret, consumer_key)
consumer = OAuth::Consumer.new(consumer_key, "", { :site => site, :scheme => :header, :signature_method => "PLAINTEXT"})
access_token = OAuth::AccessToken.new(consumer, key, secret)
return access_token.request(:get, uri)
end
response = perform_API_request("http://server:5240/MAAS/api/2.0", "/nodes/?op=list", "<key>", "<secret>", "consumer_key")

curl --header "Authorization: OAuth oauth_version=1.0, oauth_signature_method=PLAINTEXT, oauth_consumer_key=$API_KEY[1], oauth_token=$API_KEY[2], oauth_signature=&$API_KEY[3], oauth_nonce=$(uuidgen), oauth_timestamp=$(date +%s)" $MAAS_URL/MAAS/api/2.0/users/

set API_KEY (string split : $API_KEY)
http $MAAS_URL/api/2.0/users/ Authorization:"OAuth oauth_version=1.0, oauth_signature_method=PLAINTEXT, oauth_consumer_key=$API_KEY[1], oauth_token=$API_KEY[2], oauth_signature=&$API_KEY[3], oauth_nonce=$(uuidgen), oauth_timestamp=$(date +%s)"
Your API key comprises <consumer_key>:<consumer_token>:<secret>; use it to perform authenticated requests.
