Modify an API request for a particular endpoint

Modify the basic request for an API by adding a path and any other path-specific properties.

Usage

req_modify(
  req,
  ...,
  path = NULL,
  query = NULL,
  body = NULL,
  mime_type = NULL,
  method = NULL
)

Arguments

req: (httr2_request) A httr2::request() object.
...: These dots are for future extensions and must be empty.
path: (character or list) The route to an API endpoint. Optionally, a list or character vector with the path as one or more unnamed arguments (which will be concatenated with "/") plus named arguments to glue::glue() into the path.
query: (character or list) An optional list or character vector of parameters to pass in the query portion of the request. Can also include a .multi argument to pass to httr2::req_url_query() to control how elements containing multiple values are handled.
body: (multiple types) An object to use as the body of the request. If any component of the body is a path, pass it through fs::path() or otherwise give it the class "fs_path" to indicate that it is a path.
mime_type: (length-1 character) The mime type of any files present in the body. Some APIs allow you to leave this as NULL for them to guess.
method: (length-1 character, optional) If the method is something other than GET or POST, supply it. Case is ignored.

Value

A httr2::request() object.
