#initialize(cause, status_code = nil, status_message = '') ⇒ WebApiError

Creates a new ‘WebApiError` with an error message according to the given `cause`. If this cause is `:status_bad` (which will origin from the Web API itself) or `:http_error` the details about this failed request will be taken from `status_code` and `status_message`.

Parameters:

  • cause (:http_error, :invalid_key, :status_bad, :unauthorized) —

    A symbolic name for the problem which caused this error:

    • ‘:http_error`: An error during the HTTP request itself will result

      in an error with this reason.

    • ‘:invalid_key`: This occurs when trying to set a Web API key that

      isn't valid, i.e. a 128 bit integer in a hexadecimal string.

    • ‘:status_bad`: This is caused by a successful request that fails for some Web API internal reason (e.g. an invalid argument). Details about this failed request will be taken from `status_code` and `status_message`.

    • ‘:unauthorized`: This happens when a Steam Web API request is rejected as unauthorized. This most likely means that you did not specify a valid Web API key using WebApi.api_key=. A Web API key can be obtained from steamcommunity.com/dev/apikey.

    Other undefined reasons will cause a generic error message.

  • status_code (Fixnum) (defaults to: nil) —

    The HTTP status code returned by the Web API

  • status_message (String) (defaults to: '') —

    The status message returned in the response
