httr2 (version 1.0.3)

req_cookie_preserve: Preserve cookies across requests

Description

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.

Usage

req_cookie_preserve(req, path)

Arguments

req

A request.

path

A path to a file where cookies will be read from before and updated after the request.

Examples

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))
