b) By query with cURL

This case has already been presented in article: How to order products using Finder API on CREODIAS.

CURL is a tool to send data to the server using several protocols such as HTTP. In this example, the output is being filtered by grep and awk commands to obtain a token. In the Linux operating system it’s being seen as environmental variable KEYCLOAK_TOKEN.

export KEYCLOAK_TOKEN=$(curl -d 'client_id=CLOUDFERRO_PUBLIC' \
                             -d "username=${OS_USERNAME}" \
                             -d "password=${OS_PASSWORD}" \
                             -d 'grant_type=password' \
                             'https://identity.cloudferro.com/auth/realms/DIAS/protocol/openid-connect/token' | \
                             python3 -m json.tool | grep "access_token" | awk -F\" '{print $4}')

c) By Python script

import json
import requests

def get_keycloak(username: str, password: str) -> str:
    data = {
        "client_id": "CLOUDFERRO_PUBLIC",
        "username": username,
        "password": password,
        "grant_type": "password",
    }
    try:
        r = requests.post(
            "https://identity.cloudferro.com/auth/realms/DIAS/protocol/openid-connect/token",
            data=data,
        )
        r.raise_for_status()
    except Exception as e:
        raise Exception(
            f"Keycloak token creation failed. Reponse from the server was: {r.json()}"
        )
    return r.json()["access_token"]

keycloak_token = get_keycloak(username, password)
