req_verbose()
uses the following prefixes to distinguish between
different components of the HTTP requests and responses:
*
informative curl messages->
request headers>>
request body<-
response headers<<
response body
Usage
req_verbose(
req,
header_req = TRUE,
header_resp = TRUE,
body_req = FALSE,
body_resp = FALSE,
info = FALSE,
redact_headers = TRUE
)
Arguments
- req
A request.
- header_req, header_resp
Show request/response headers?
- body_req, body_resp
Should request/response bodies? When the response body is compressed, this will show the number of bytes received in each "chunk".
- info
Show informational text from curl? This is mainly useful for debugging https and auth problems, so is disabled by default.
- redact_headers
Redact confidential data in the headers? Currently redacts the contents of the Authorization header to prevent you from accidentally leaking credentials when debugging/reprexing.
Value
A modified HTTP request.
See also
req_perform()
which exposes a limited subset of these options
through the verbosity
argument and with_verbosity()
which allows you
to control the verbosity of requests deeper within the call stack.
