FILE: sample_authentication.py
DESCRIPTION:
These samples demonstrate authenticating an EventGridPublisherClient.
USAGE:
python sample_authentication.py
Set the environment variables with your own values before running the sample:
1) EVENTGRID_TOPIC_KEY - The access key of your eventgrid account.
2) EVENTGRID_TOPIC_ENDPOINT - The topic hostname. Typically it exists in the format
"https://<YOUR-TOPIC-NAME>.<REGION-NAME>.eventgrid.azure.net/api/events".
3) EVENTGRID_SAS - The shared access signature that is to be used to authenticate the client.
