We’re well pleased to announce the release of httr 1.4.0. The goal of httr is to provide a wrapper for the curl package, customised to the demands of modern web APIs.

The httr 1.4.0 release includes improved flexibility for OAuth 2.0 , new and updated demos , and several minor changes and improvements — the full details of which can be found in the changelog .

OAuth 2.0 improvements#

OAuth 2.0 has been made somewhat more flexible in order to support more websites. init_oauth2.0() now passes use_basic_auth onward, enabling basic authentication for OAuth 2.0. oauth2.0_token() and init_oauth2.0() have gained two new arguments:

  • oob_value specifies the value to use for the redirect_uri parameter when retrieving an authorization URL, necessary when using “out-of-band” (oob) configuration.
  • query_authorize_extra makes it possible to add extra query parameters to the authorization URL, as is required by some APIs.

Scopes are now de-duplicated, sorted and stripped of names before being hashed for on-disk token retrieval. This eliminates a source of hash mismatch that could cause new tokens to be requested, even when existing tokens had the necessary scope.

Demo updates#

Thanks to Christophe Dervieux , a new demo for OAuth 1.0a’s one-legged authentication mechanism has been added, using the Noun Project API.

The Faceboook demo now uses device flow . This means that you can continue to use the Facebook API from R under their new security policy.

The Vimeo demo has been updated to use OAuth 2.0.
