last_response: Retrieve most recent request/response

In httr2: Perform HTTP Requests and Process the Responses

Retrieve most recent request/response

Description

last_request() and last_response() retrieve the most recent request made by httr2 and the response it received, to facilitate debugging problems after they occur.

last_request_json() and last_response_json() return the JSON bodies of the most recent request and response. They will error if not JSON.

Usage

last_response()

last_request()

last_request_json(pretty = TRUE)

last_response_json(pretty = TRUE)

Arguments

pretty

Should the JSON be pretty-printed?

Value

last_request() and last_response() return an HTTP request or response respectively. If no request has been made, last_request() will return NULL; if no request has been made or the last request was unsuccessful, last_response() will return NULL.

last_request_json() and last_response_json() always return a string. They will error if last_request() or last_response() are NULL or don't have JSON bodies.

Examples

. <- request("http://httr2.r-lib.org") |> req_perform()
last_request()
last_response()

. <- request(example_url("/post")) |>
  req_body_json(list(a = 1, b = 2)) |>
  req_perform()
last_request_json()
