FILE: sample_authentication_async.py
DESCRIPTION:
This sample demonstrates how to authenticate to the Form Recognizer service.
There are two supported methods of authentication:
1) Use a Form Recognizer API key with AzureKeyCredential from azure.core.credentials
2) Use a token credential from azure-identity to authenticate with Azure Active Directory
See more details about authentication here:
https://docs.microsoft.com/azure/cognitive-services/authentication
USAGE:
python sample_authentication_async.py
Set the environment variables with your own values before running the sample:
1) AZURE_FORM_RECOGNIZER_ENDPOINT - the endpoint to your Form Recognizer resource.
2) AZURE_FORM_RECOGNIZER_KEY - your Form Recognizer API key
3) AZURE_CLIENT_ID - the client ID of your active directory application.
4) AZURE_TENANT_ID - the tenant ID of your active directory application.
5) AZURE_CLIENT_SECRET - the secret of your active directory application.
6) AZURE_FORM_RECOGNIZER_AAD_ENDPOINT - the endpoint to your Form Recognizer resource for using AAD.
