Get Default Token Provider Function

Description

Creates a token provider function that retrieves authentication credentials and returns a callable token getter. This function handles the credential discovery process and returns the token acquisition method from the discovered credential object.

Usage

get_token_provider(
  scope = NULL,
  tenant_id = NULL,
  client_id = NULL,
  client_secret = NULL,
  use_cache = "disk",
  offline = TRUE,
  chain = default_credential_chain()
)

Arguments

scope	Optional character string specifying the authentication scope.
tenant_id	Optional character string specifying the tenant ID for authentication.
client_id	Optional character string specifying the client ID for authentication.
client_secret	Optional character string specifying the client secret for authentication.
use_cache	Character string indicating the caching strategy. Defaults to "disk". Options include "disk" for disk-based caching or "memory" for in-memory caching.
offline	Logical. If TRUE, adds 'offline_access' to the scope to request a 'refresh_token'. Defaults to TRUE.
chain	A list of credential objects, where each element must inherit from the Credential base class. Credentials are attempted in the order provided until get_token succeeds.

Value

A function that retrieves and returns an authentication token when called.
