These functions pass their arguments to base::gsub() in order to find and
replace string patterns (regular expressions) within request or response
objects. gsub_request() replaces in the request URL and any request body
fields; gsub_response() replaces in the response URL, the response body,
and it calls gsub_request() on the request object found within the
response.
gsub_response(response, pattern, replacement, ...)gsub_request(request, pattern, replacement, ...)
A request or response object, same as was passed in, with the
pattern replaced in the URLs and bodies.
An 'httr' response object to sanitize.
From base::gsub(): "character string containing a regular
expression (or character string for fixed = TRUE) to be matched in the
given character vector." Passed to gsub(). See the docs for gsub() for
further details.
A replacement for the matched pattern, possibly including
regular expression backreferences. Passed to gsub(). See the docs for
gsub() for further details.
Additional logical arguments passed to gsub(): ignore.case,
perl, fixed, and useBytes are the possible options.
An 'httr' request object to sanitize.
Note that, unlike gsub(), the first argument of the function is request
or response,
not pattern, while the equivalent argument in gsub(), "x", is placed
third. This difference is to maintain consistency with the other redactor
functions in httptest, which all take response as the first argument.
