Token-class function

OAuth token objects.

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(). class

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-oauth file is already present, OR
• getOption("httr_oauth_cache") is TRUE

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.
