ladder_auth_configure: Edit and view auth configuration

Description

These functions give more control over and visibility into the auth configuration than ladder_auth() does. ladder_auth_configure() lets the user specify their own:

OAuth client, which is used when obtaining a user token.
API key. If ladder is de-authorized via ladder_deauth(), all requests are sent with an API key in lieu of a token.

See the vignette("get-api-credentials", package = "gargle") for more. If the user does not configure these settings, internal defaults are used.

ladder_oauth_client() and ladder_api_key() retrieve the currently configured OAuth client and API key, respectively.

Usage

ladder_auth_configure(client, path, api_key, app)
ladder_api_key()
ladder_oauth_client()

Value

ladder_auth_configure(): An object of R6 class gargle::AuthState, invisibly.
ladder_oauth_client(): the current user-configured OAuth client.
ladder_api_key(): the current user-configured API key.

Arguments

client: A Google OAuth client, presumably constructed via gargle::gargle_oauth_client_from_json(). Note, however, that it is preferred to specify the client with JSON, using the path argument.
path: JSON downloaded from Google Cloud Console, containing a client id and secret, in one of the forms supported for the txt argument of jsonlite::fromJSON() (typically, a file path or JSON string).
api_key: API key.
app: Replaced by the client argument.

Examples

Run this code

# see and store the current user-configured OAuth client (probaby `NULL`)
(original_client <- ladder_oauth_client())

# see and store the current user-configured API key (probaby `NULL`)
(original_api_key <- ladder_api_key())

# the preferred way to configure your own client is via a JSON file
# downloaded from Google Developers Console
# this example JSON is indicative, but fake
path_to_json <- system.file(
  "extdata", "client_secret_installed.googleusercontent.com.json",
  package = "gargle"
)
ladder_auth_configure(path = path_to_json)

# this is also obviously a fake API key
ladder_auth_configure(api_key = "the_key_I_got_for_a_google_API")

# confirm the changes
ladder_oauth_client()
ladder_api_key()

# restore original auth config
ladder_auth_configure(client = original_client, api_key = original_api_key)
