class

TwitchEventSub::HttpServer::TwitchHandler

Inherits HTTP::Handler < Reference < Object

The TwitchHandler encapsulates the logic necessary to handle callbacks from Twitch. This class should be subclassed with handle_TYPE methods defined for each type of Twitch notification that will be handled. For example, to monitor channel follow events, the subscription type from Twitch is channel.follow. The corresponding method to handle this event type would be handle_channel_follow.

signature_matches?(request, body, params)

Compare the signature passed as a param to the HMAC-SHA256 signature that is calculated from the message contents to ensure that they match. TODO: Make this method look at the HMAC encoding technique that Twitch indicates was used in the signature. i.e. sha256=0036753bef53872d35c7f24643abaacd95c554d371d563df37eb9d721c457892 and dynamically use the same one. That way, if Twitch changes to a different algorithm, the system will not need any changes to use the new one.
