Set Environment Variables

If your demo requires environment variables (for instance, Application credentials), you can set them in theSettings of your Demo. You can access them in your code like regular environment variables, for example with os.getenv() in Python.

As an example, below is an excerpt of our Gradio starter template:

import os
from planqk.service.client import PlanqkServiceClient

consumer_key = os.getenv('CONSUMER_KEY', None)
consumer_secret = os.getenv('CONSUMER_SECRET', None)
service_endpoint = "https://gateway.platform.planqk.de/anaqor/quantum-random-number-generator/1.0.0"

def run(n_numbers: int):
    client = PlanqkServiceClient(service_endpoint, consumer_key, consumer_secret)
    job = client.start_execution(data=data, params=params)
    result = client.get_result(job.id)

    random_number_list = result["result"]["random_number_list"]
    return ", ".join([str(x) for x in random_number_list])

The code calls the Quantum Random Number Generator Service using the planqk-service-sdk. The service is available as a free service on the PlanQK Marketplace. To access the service, a subscription to the service is needed. We can add the consumer key and secret of the subscribed Application as environment variables to the Demo.
