auth_code: Authorization

Description

Authorize your R session to connect to an ArcGIS Portal. See details.

Usage

auth_code(client = Sys.getenv("ARCGIS_CLIENT"), host = arc_host())
auth_client(
  client = Sys.getenv("ARCGIS_CLIENT"),
  secret = Sys.getenv("ARCGIS_SECRET"),
  host = arc_host(),
  expiration = 120
)
auth_binding()
auth_user(
  username = Sys.getenv("ARCGIS_USER"),
  password = Sys.getenv("ARCGIS_PASSWORD"),
  host = arc_host(),
  expiration = 60
)
auth_key(api_key = Sys.getenv("ARCGIS_API_KEY"), host = arc_host())
refresh_token(token, client = Sys.getenv("ARCGIS_CLIENT"), host = arc_host())
validate_or_refresh_token(
  token,
  client = Sys.getenv("ARCGIS_CLIENT"),
  host = arc_host(),
  refresh_threshold = 10,
  call = rlang::caller_env()
)

Value

an httr2_token

Arguments

client

an OAuth 2.0 developer application client ID. By default uses the environment variable ARCGIS_CLIENT.

host

default "https://www.arcgis.com". The host of your ArcGIS Portal.

secret

an OAuth 2.0 developer application secret. By default uses the environment variable ARCGIS_SECRET.

expiration

the duration of the token in minutes.

username

default Sys.getenv("ARCGIS_USER"). Your username to login. Do not hard code this value.

password

default Sys.getenv("ARCGIS_PASSWORD"). Your password to login. Do not hard code this value.

api_key

default Sys.getenv("ARCGIS_API_KEY"). A character scalar of an ArcGIS Developer API key.

token

an httr2_token as created by auth_code() or similar

refresh_threshold

default 10. If token expiry is within this threshold (in seconds) the token will be refreshed only if a refresh_token is available. Token refreshing is only possible with auth_code() flow.

call

The execution environment of a currently running function, e.g. call = caller_env(). The corresponding function call is retrieved and mentioned in error messages as the source of the error.

You only need to supply call when throwing a condition from a helper function which wouldn't be relevant to mention in the message.

Can also be NULL or a defused function call to respectively not display any call or hard-code a code to display.

For more information about error calls, see Including function calls in error messages.

Details

ArcGIS Online and Enterprise Portals utilize OAuth2 authorization via their REST APIs.

• auth_code() is the recommend OAuth2 workflow for interactive sessions

• auth_client() is the recommended OAuth2 workflow for non-interactive sessions

• auth_user() uses legacy username and password authorization using the generateToken endpoint. It is only recommended for legacy systems that do not implement OAuth2.

• auth_binding() fetches a token from the active portal set by arcgisbinding. Uses arcgisbinding::arc.check_portal() to extract the authorization token. Recommended if using arcgisbinding.

Examples

if (FALSE) {
auth_code()
auth_client()
auth_user()
auth_key()
