Retrieve most recent request/response

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.
