  txt = NULL,
  ...
)

Arguments

host: String with the host. The default is "http://localhost:8080".
path: String with the path to the called end point, e.g. "version", "data/upload" or "data/upload/json".
query: A list with query arguments, for example, list(auto_unbox = TRUE) for json output, or list(width = 7.09, height = 7.09) for svglite.
