Temporarily set verbosity for all requests — with

with_verbosity() is useful for debugging httr2 code buried deep inside another package because it allows you to see exactly what's been sent and requested.

Usage

with_verbosity(code, verbosity = 1)

Arguments

code

Code to execture

verbosity

How much information to print? This is a wrapper around req_verbose() that uses an integer to control verbosity:

0: no output
1: show headers
2: show headers and bodies
3: show headers, bodies, and curl status messages.

Use with_verbosity() to control the verbosity of requests that you can't affect directly.

Value

The result of evaluating code.

Examples

fun <- function() {
  request("https://httr2.r-lib.org") |> req_perform()
}
with_verbosity(fun())
