Parse one or more responses — resp

If you have implemented the full nectar framework, use resp_tidy() directly to parse your responses. We may continue to support resp_parse(), but it is most useful as a bridge to the full framework.

httr2 provides two methods for performing requests: httr2::req_perform(), which returns a single httr2::response() object, and httr2::req_perform_iterative(), which returns a list of httr2::response() objects. This function automatically determines whether a single response or multiple responses have been returned, and parses the responses appropriately.

Usage

resp_parse(resps, ...)

# Default S3 method
resp_parse(
  resps,
  ...,
  arg = rlang::caller_arg(resps),
  call = rlang::caller_env()
)

# S3 method for class 'httr2_response'
resp_parse(resps, ..., response_parser = resp_tidy)

Arguments

resps: (httr2_response, nectar_responses, or list) A single httr2::response() object (as returned by httr2::req_perform()) or a list of such objects (as returned by req_perform_opinionated() or httr2::req_perform_iterative()).
...: Additional arguments passed on to the response_parser function (in addition to resps).
arg: (length-1 character) An argument name as a string. This argument will be mentioned in error messages as the input that is at the origin of a problem.
call: (environment) The environment from which a function was called, e.g. rlang::caller_env() (the default). The environment will be mentioned in error messages as the source of the error. This argument is particularly useful for functions that are intended to be called as utilities inside other functions.
response_parser: (function) A function to parse the server response (resp). Defaults to httr2::resp_body_json(), since JSON responses are common. Set this to NULL to return the raw response from httr2::req_perform().

Value

The response parsed by the response_parser. If resps was a list, the parsed responses are concatenated when possible. Unlike httr2::resps_data, this function does not concatenate raw vector responses.
