Class Method Details

.raise_exception(response) ⇒ Object

In the event of a non-200 HTTP status code, this method takes the HTTP response, parses the JSON from the body to get more information about the exception, then raises the proper error. Note that all exceptions are scoped in the CloudLB::Exception namespace.
