Installs request, response, and error steps that log API calls

Options

• :api_name (mandatory) - name of the api; will be available to the app as metadata
• :log_level (default :info) - level at which then logging is done
• :hide_request_keys (default []) - list of request keys that should be hidden (for json or form requests)
• :hide_response_keys (default []) - list of response keys that should be hidden (for json responses)
• :hide_request_headers (default []) - list of request headers that should be hidden
• :hide_response_headers (default []) - list of response headers (and trailers) that should be hidden

These same options can also be passed through Req options to change the behavior on a per-request basis.

Examples

By default, log requests, responses and errors at level :debug with name "my_api" in metadata

req = Req.new() |> ReqApiLogger.attach(api_name: "my_api", log_level: :debug)

# send request, log with options passed to attach/1
Req.get!(req, url: "https://example.org")

# on this request only, log at level :warning, while hiding keys from the request query and response headers
Req.get!(req,
  json: %{login: "foo", password: "bar"}
  url: "https://example.org",
  log_level: :warning,
  hide_request_keys: ["password"],
  hide_response_headers: ["x-private-header"]
)
