Cannot get Azure subscriptions using Azure Python SDK

I can get Azure subscriptons list using REST API.

However, when I'm switching to Azure Python SDK, there seems to be some problems.

This is the code so far:

from azure.identity.aio import ClientSecretCredential
from azure.mgmt.resource import SubscriptionClient
import json

data = json.load(open("parameters.json"))

credential = ClientSecretCredential(
    tenant_id=data["tenant"],
    client_id=data["client_id"],
    client_secret=data["client_secret"],
)

subs = SubscriptionClient(credential=credential)
l = list(subs.subscriptions.list())
print(l)

I use an additional list in the pnultimate line because subs.subscriptions.list() returns an iterator. Despite that, the code seems pretty straightforward.

However, this code gives the following error:

AttributeError: 'coroutine' object has no attribute 'token'
sys:1: RuntimeWarning: coroutine 'GetTokenMixin.get_token' was never awaited

I don't know what was missing, and the error didn't gives much information.

It seems it was related with token. I can get a token with the following method:

async def print_token():
    token = await credential.get_token("https://management.azure.com/.default")
    print(token.token)
    await credential.close()

asyncio.run(print_token())

But it requires asyncio to run, which isn't compatible with my code. And where should I should put the token?

I've investigated the source code if Azure CLI. It seems it get subscriptions using the same method: https://github.com/Azure/azure-cli/blob/f369cead2604e37480611b0cc269fee615956ea2/src/azure-cli-core/azure/cli/core/_profile.py#L835

The client was acqurired from the function below, and the type was

https://github.com/Azure/azure-cli/blob/f369cead2604e37480611b0cc269fee615956ea2/src/azure-cli-core/azure/cli/core/profiles/_shared.py#L60

Which is essentially the SubscriptionClient.

Initially, I too got same error when I ran your code in my environment like this:

from azure.identity.aio import ClientSecretCredential
from azure.mgmt.resource import SubscriptionClient
import json

data = json.load(open("parameters.json"))

credential = ClientSecretCredential(
    tenant_id=data["tenant"],
    client_id=data["client_id"],
    client_secret=data["client_secret"],
)

subs = SubscriptionClient(credential=credential)
l = list(subs.subscriptions.list())
print(l)

Response:

To list subscriptions using Azure Python SDK without asyncio module, make use of below modified code:

from azure.identity import ClientSecretCredential
from azure.mgmt.resource import SubscriptionClient
import json

with open("parameters.json") as f:
    data = json.load(f)

credential = ClientSecretCredential(
    tenant_id=data["tenant"],
    client_id=data["client_id"],
    client_secret=data["client_secret"],
)

subs_client = SubscriptionClient(credential)

subscriptions = subs_client.subscriptions.list()

for subscription in subscriptions:
    #print(f"Subscription ID: {subscription.subscription_id}, Display Name: {subscription.display_name}")
    print(json.dumps(subscription.as_dict(), indent=2))
