I am building a service that needs to create at runtime a servicebus namespace, topic and subscriptions. I need to genrate the sas token(or url) to the subscription created by the service and send it to other services in the system.
How can i generate the sas token with the azure python sdk
I'd note in addition to Jim's accurate answer: one can also approach this using the azure-mgmt-servicebus SDK. It would require using azure.common.credentials.ServicePrincpalCredential for authentication, but would give a slightly more structured flow; not only to create the namespace and topic/subscription, but to create or update authorization rules against a given topic or the namespace itself, and then fetch your keys programmatically.
See the following as a self-contained example:
from azure.mgmt.servicebus import ServiceBusManagementClient
from azure.common.credentials import ServicePrincipalCredentials
from azure.mgmt.servicebus.models import AccessRights
client_id = 'REPLACEME'
client_secret = 'REPLACEME'
subscription = 'REPLACEME'
tenant = 'REPLACEME'
resource_group_name = 'REPLACEME'
namespace_name = 'REPLACEME'
authorization_rule_name = 'REPLACEME'
topic_name = 'REPLACEME'
subscription_name = 'REPLACEME'
authorization_rule_rights = [AccessRights.manage]
credential = ServicePrincipalCredentials(client_id, client_secret, tenant=tenant)
client = ServiceBusManagementClient(credential, subscription)
client.namespaces.create_or_update(resource_group_name, namespace_name)
client.topics.create_or_update(resource_group_name, namespace_name, topic_name)
client.subscriptions.create_or_update(resource_group_name, namespace_name, topic_name, subscription_name)
client.topics.create_or_update_authorization_rule(resource_group_name, namespace_name, topic_name, authorization_rule_name, authorization_rule_rights)
rule = client.topics.list_keys(resource_group_name, namespace_name, topic_name, authorization_rule_name)
As always, full disclosure, I'm one of the folks maintaining the python azure servicebus lib, so don't hesitate to shout if any of this is unclear.
