Setting up a session

To establish a session with username/password login, use the following code:

username = "" #(user name as obtained from external source)
password = "" #(password as obtained from external source)
session = requests.session()
response = session.get(login_url)
session.headers['referer'] = response.url
payload = {'username':username,'password':password,'csrfmiddlewaretoken': session.cookies['arccsrftoken']}
session.post(login_url, data = payload)

To establish a session through the Cloudera API Key system and avoid the login process, use the following code:

apikey = (apikey string)
session = requests.session()
session.headers['AUTHORIZATION'] = 'apikey %s' % apikey

After setting up a session, you can fetch the entire data from all datasets in the system by using the following code:

response = session.get(api_url + 'datasets?detail=1')
datasets = response.json()
