将托管标识与 Azure 服务总线一起使用

Question

I want to use a managed identity to connect to Azure Service Bus. In the docs they mention the DefaultAzureCredentialBuilder. I don't really get how this would use my managed identity to authenticate to the Service Bus.

Does anyone know this?

Answer 1

DefaultAzureCredential is a chained credential; internally it considers multiple authorization sources, including managed identities. More information can be found in the Azure.Identity overview .

Service Bus can use any of the Azure.Identity credentials for authorization. DefaultAzureCredentialBuilder is demonstrated only because it allows for success in a variety of scenarios.

If you'd prefer to restrict authorization to only a managed identity, you can do so by using ManagedIdentityCredentialBuilder rather than the default credential. An example of creating the can be found here . It can then be passed to Service Bus in the same manner as the default credential.
