Class Method Details

.get(url) ⇒ Hash

Get the JSON at the given URL and parse it as such. This method is just a very thin wrapper around Ruby’s native OpenURI with some error- handling magic.

Parameters:

  • url (String) —

    the url to get

Returns:

  • (Hash) —

    the parsed JSON hash

Raises:

  • (RuntimeError) —

    if the request fails (40X, 50X, bad-URL) or if the JSON is invalid
