(Chilkat2-Python) Azure REST API Access Token

Demonstrates how to request an Azure REST API OAUTH2 access token.

Note: In order to access resources a Service Principal needs to be created in your Tenant. It is really convenient to do it via AZ CLI:

az ad sp create-for-rbac --name [APP_NAME] --password [CLIENT_SECRET]

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

rest = chilkat2.Rest()

# URL: https://login.microsoftonline.com/TENANT_ID/oauth2/token
bTls = True
port = 443
bAutoReconnect = True
success = rest.Connect("login.microsoftonline.com",port,bTls,bAutoReconnect)
if (success != True):
    print("ConnectFailReason: " + str(rest.ConnectFailReason))
    print(rest.LastErrorText)
    sys.exit()

# Add query params to the request.
rest.AddQueryParam("grant_type","client_credentials")
rest.AddQueryParam("client_id","APP_ID")
rest.AddQueryParam("client_secret","CLIENT_SECRET")
rest.AddQueryParam("resource","https://management.azure.com/")

strResponseBody = rest.FullRequestFormUrlEncoded("POST","/TENANT_ID/oauth2/token")
if (rest.LastMethodSuccess != True):
    print(rest.LastErrorText)
    sys.exit()

respStatusCode = rest.ResponseStatusCode
if (respStatusCode >= 400):
    print("Response Status Code = " + str(respStatusCode))
    print("Response Header:")
    print(rest.ResponseHeader)
    print("Response Body:")
    print(strResponseBody)
    sys.exit()

json = chilkat2.JsonObject()
json.Load(strResponseBody)
json.EmitCompact = False
print(json.Emit())

# The result is an access token such as the following:

# {
#   "token_type": "Bearer",
#   "expires_in": "3600",
#   "ext_expires_in": "3600",
#   "expires_on": "1557864616",
#   "not_before": "1557860716",
#   "resource": "https://management.azure.com/",
#   "access_token": "eyJ0eXAiOiJKV1QiL ... 20UFDDOHEyUg"
# }

# We'll save this JSON to a file for other examples to use..
