httr (version 1.1.0)

Token-class: OAuth token objects.

Description

These objects represent the complete set of data needed for OAuth access: an app, an endpoint, cached credentials and parameters. They should be created through their constructor functions oauth1.0_token and oauth2.0_token.

Usage

Token

Token1.0

Token2.0

TokenServiceAccount

Arguments

format

An R6 class object.

Methods

  • cache(): caches token to disk
  • sign(method, url): returns list of url and config
  • refresh(): refresh access token (if possible)
  • validate(): TRUE if the token is still valid, FALSE otherwise

Caching

OAuth tokens are cached on disk in a file called .httr-oauth saved in the current working directory. Caching is enabled if:

  • The session is interactive, and the user agrees to it, OR
  • The.httr-oauthfile is already present, OR
  • getOption("httr_oauth_cache")isTRUE

You can suppress caching by setting the httr_oauth_cache option to FALSE.

Tokens are cached based on their endpoint and parameters.

The cache file should not be included in source code control or R packages (because it contains private information), so httr will automatically add the appropriate entries to `.gitignore` and `.Rbuildignore` if needed.
