module Spam
|
|
##
|
|
# This class is a Parameter Object (https://refactoring.com/catalog/introduceParameterObject.html)
|
|
# which acts as an container abstraction for multiple values related to spam and
|
|
# captcha processing for a provided HTTP request object.
|
|
#
|
|
# It is used to encapsulate these values and allow them to be passed from the Controller/GraphQL
|
|
# layers down into to the Service layer, without needing to pass the entire request and therefore
|
|
# unnecessarily couple the Service layer to the HTTP request.
|
|
#
|
|
# Values contained are:
|
|
#
|
|
# captcha_response: The response resulting from the user solving a captcha. Currently it is
|
|
# a scalar reCAPTCHA response string, but it can be expanded to an object in the future to
|
|
# support other captcha implementations such as FriendlyCaptcha. Obtained from
|
|
# request.headers['X-GitLab-Captcha-Response']
|
|
# spam_log_id: The id of a SpamLog record. Obtained from request.headers['X-GitLab-Spam-Log-Id']
|
|
# ip_address = The remote IP. Obtained from request.env['action_dispatch.remote_ip']
|
|
# user_agent = The user agent. Obtained from request.env['HTTP_USER_AGENT']
|
|
# referer = The HTTP referer. Obtained from request.env['HTTP_REFERER']
|
|
#
|
|
# NOTE: The presence of these values in the request is not currently enforced. If they are missing,
|
|
# then the spam check may fail, or the SpamLog or UserAgentDetail may have missing fields.
