Each request returns a 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()
to get user tokens, and
sign_oauth1.0()
and sign_oauth2.0()
to sign
requests. The demos directory has twelve demos of using OAuth: four for 1.0
(linkedin, twitter, vimeo, and yahoo) and eight for 2.0 (azure, facebook,
github, google, linkedin, reddit, yahoo, and yelp).
