httr is organised around the five most common http
verbs: GET, PATCH,
POST, HEAD,
PUT, and DELETE.response object
which provides easy access to status code, cookies,
headers, timings, and other useful info. The content of
the request is available as a raw vector
(content), character vector
(text_content), or parsed into an R object
(parsed_content), currently for html, xml,
json, png and jpeg). Requests can be modified by various config options like
set_cookies, add_headers,
authenticate, use_proxy,
verbose, and timeout
httr supports OAuth 1.0 and 2.0. Use
oauth1.0_token and
oauth2.0_token get user tokens, and
sign_ouath1.0 and
sign_ouath2.0 to sign requests. The demos
directory has six demos of using OAuth: three for 1.0
(linkedin,twitter and vimeo) and three for 2.0 (facebook,
github, google).
