az_cli_get_token: Get Access Token from Azure CLI

In azr: Credential Chain for Seamless 'OAuth 2.0' Authentication to 'Azure Services'

Get Access Token from Azure CLI

Description

Retrieves an access token from Azure CLI using the ⁠az account get-access-token⁠ command. This is a lower-level function that directly interacts with the Azure CLI to obtain OAuth2 tokens.

Usage

az_cli_get_token(scope, tenant_id = NULL, timeout = 10L)

Arguments

scope	A character string specifying the OAuth2 scope for which to request the access token (e.g., "https://management.azure.com/.default").
tenant_id	A character string specifying the Azure Active Directory tenant ID. If NULL, uses the default tenant from Azure CLI. Defaults to NULL.
timeout	A numeric value specifying the timeout in seconds for the Azure CLI process. Defaults to 10.

Details

This function executes the Azure CLI command and parses the JSON response to create an httr2 OAuth token object. The token includes the access token, token type, and expiration time.

Value

An httr2::oauth_token() object containing:

• access_token: The OAuth2 access token string

• token_type: The type of token (typically "Bearer")

• .expires_at: POSIXct timestamp when the token expires

Examples

  scope = "https://graph.microsoft.com/.default",
