req_cookie_preserve | R Documentation |
Use req_cookie_set()
to set client side cookies that are sent to the
server.
By default, httr2 uses a clean slate for every request meaning that cookies
are not automatically preserved across requests. To preserve cookies, use
req_cookie_preserve()
along with the path to cookie file that will be
read before and updated after each request.
req_cookie_preserve(req, path)
req_cookies_set(req, ...)
req |
A httr2 request object. |
path |
A path to a file where cookies will be read from before and updated after the request. |
