This quick how-to was written with python 23.710.11 8 and requests 2.828.10

Step-by-step guide

The following steps demonstrate how get_token.py workshow to get an access token:

1. Import requests, sys, getpass and requests.auth.HTTPBasicAuth to handle endpoint authentication.

   Code Block
   language py
   import getpass import sys import requests from requests.auth import HTTPBasicAuth

   
   

2. Get user from input and password via getpass.getpass() so it's not prompted.

   Code Block
   language py
   # input argument usr = sys.argv[1] # Prompt the user for a password without echoing. pwd = getpass.getpass()

   
   

3. Set the authentication endpoint

   Code Block
   language py
   token_endpoint = 'https://vss-api.eis.utoronto.ca/auth/request-token'

   
   

4. Make a POST request to token_request and create a new HTTPBasicAuth object initializing it with usr and pwd

   Code Block
   language py
   # NO MFA r = requests.post(url=token_endpoint, auth=HTTPBasicAuth(usr, pwd)) # With MFA r = requests.post(url=token_endpoint, auth=HTTPBasicAuth(usr, pwd), json={'otp': '00000'})

5. Get JSON response body

   Code Block
   language py
   data = r.json()

6. Print Error if any or the token if succeeded:

   Code Block
   language py
   if r.ok: print

...

1. (f"TOKEN={

...

1. data['token']}") else: print

...

1. (f"ERROR: {

...

1. r.status_code

...

1. } {data['

...

1. type']

...

1. }: {data['message']}")

Script

Full python script is showing below:

#!/usr/bin/env python

# importing modules
import getpass
import sys
import requests
from requests.auth import HTTPBasicAuth

# input argument
usr = sys.argv[1]

# Prompt the user for a password without echoing.
pwd = getpass.getpass()

# authentication endpoint
token_endpoint = 'https://vss-api.eis.utoronto.ca/auth/request-token'

# making post request
r = requests.post(url=token_endpoint, auth=HTTPBasicAuth(usr, pwd))
data = r.json()

# getting token or printing error
if r.ok:
    print '(f"TOKEN={}'.format(data['token']}")
else:
    print 'ERROR: {} {}(f"ERROR: {}'.format(r.status_code,} {data['errortype'],}: {data['message']}")
