GitHub-WebHook

GitHub-WebHook copied to clipboard

This script acts as a web hook for GitHub events, processes them, and returns messages which can be sent out to an IRC channel or a Discord webhook, depending on the converter used.

See examples/discord.php for a basic application that sends webhooks to Discord.
See examples/irker.php for a basic application that sends messages to IRC.

GitHubWebHook

GitHubWebHook.php accepts, processes and validates an event, it also can make sure that the event came from a GitHub server.

Functions in this class are:

ProcessRequest()

Accepts an event, throws Exception on error.

GetEventType()

Returns event type. See https://developer.github.com/webhooks/#events for a list of events.

GetPayload()

Returns decoded JSON payload as an object.

GetFullRepositoryName()

Returns full name of the repository for which an event was sent for.

ValidateHubSignature( $SecretKey )

Retuns true if HMAC hex digest of the payload matches GitHub's, false otherwise.

~~ValidateIPAddress()~~

Returns true if a request came from GitHub's IP range, false otherwise. ⚠ Use ValidateHubSignature instead.

IrcConverter

IrcConverter.php accepts input from previous script and outputs a colored string which can be sent to IRC.

__construct( $EventType, $Payload )

IrcConverter constructor takes 3 paramaters (last one is optional). All you need to do is pass data after parsing the message with GitHubWebHook like so: new IrcConverter( $Hook->GetEventType(), $Hook->GetPayload() );

URL shortener paramater takes a function, and that function should accept a single string argument containing an url. If your function fails to shorten an url or do anything with it, your function must return the original url back.

GetMessage()

After calling the constructor, using this function will return a string which can be sent to an IRC server.

Throws NotImplementedException when you pass an event that is not parsed anyhow, and throws IgnoredEventException for fork, watch and status events which are ignored by design.
