Set query params, request body, request headers and/or basic_auth
wi_th(.data, ..., .list = list())input. Anything that can be coerced to a StubbedRequest class
object
Comma separated list of named variables. accepts the following:
query, body, headers, basic_auth. See Details.
named list, has to be one of query, body,
headers and/or basic_auth. An alternative to passing in via ....
Don't pass the same thing to both, e.g. don't pass 'query' to ..., and
also 'query' to this parameter
an object of class StubbedRequest, with print method describing
the stub
with is a function in the base package, so we went with
wi_th
Values for query, body, headers, and basic_auth:
query: (list) a named list. values are coerced to character class in the recorded stub. You can pass numeric, integer, etc., but all will be coerced to character.
body: various, including character string, list, raw, numeric,
upload (crul::upload(), httr::upload_file(), curl::form_file(), or
curl::form_data() they both create the same object in the end). for the
special case of an empty request body use NA instead of NULL because
with NULL we can't determine if the user did not supply a body or
they supplied NULL to indicate an empty body.
headers: (list) a named list
basic_auth: (character) a length two vector, username and password. We don't do any checking of the username/password except to detect edge cases where for example, the username/password were probably not set by the user on purpose (e.g., a URL is picked up by an environment variable). Only basic authentication supported https://en.wikipedia.org/wiki/Basic_access_authentication.
Note that there is no regex matching on query, body, or headers. They are tested for matches in the following ways:
query: compare stubs and requests with identical(). this compares
named lists, so both list names and values are compared
body: varies depending on the body format (list vs. character, etc.)
headers: compare stub and request values with ==. list names are
compared with %in%. basic_auth is included in headers (with the name
Authorization)
