req_cookie_preserve | R Documentation |
By default, httr2 uses a clean slate for every request meaning that cookies are not automatically preserved across requests. To preserve cookies, you must set a cookie file which will be read before and updated after each request.
req_cookie_preserve(req, path)
req |
A request. |
path |
A path to a file where cookies will be read from before and updated after the request. |
path <- tempfile()
httpbin <- request(example_url()) |>
req_cookie_preserve(path)
# Manually set two cookies
httpbin |>
req_template("/cookies/set/:name/:value", name = "chocolate", value = "chip") |>
req_perform() |>
resp_body_json()
httpbin |>
req_template("/cookies/set/:name/:value", name = "oatmeal", value = "raisin") |>
req_perform() |>
resp_body_json()
# The cookie path has a straightforward format
cat(readChar(path, nchars = 1e4))
