OAuth LTI Ошибка: запрос не проверяется?

Question

Я пытаюсь обновить устаревшее приложение, чтобы использовать версию LTI ruby ​​gem 2.2.

В настоящее время я не могу получить запросы Oauth для проверки с использованием следующего:

authenticator = IMS::LTI::Services::MessageAuthenticator.new(@request.url, @params, secret)
authenticator.valid_signature?

Насколько я могу судить, я не уверен, что является причиной этого, поскольку это должен быть действительный запрос. Вот дампы задействованных переменных:

Answer 1

Оказывается, проблема в том, что в моем запросе были дополнительные параметры, которые были переданы.

Вместо этого использовал следующее для генерации параметров для валидатора:

params = request.query_parameters.merge(request.request_parameters)
