	Validate(r *http.Request, secret []byte) ([]byte, error)
}

GithubRequestValidator handles checking if GitHub requests are signed properly by the secret.

type GitlabRequestParser

type GitlabRequestParser interface {
	// Validate validates that the request has a token header matching secret.
	// If the secret does not match it returns an error.
	// If secret is empty it does not check the token header.
	// It then parses the request as a GitLab object depending on the header
	// provided by GitLab identifying the webhook type. If the webhook type
	// is not recognized it will return nil but will not return an error.
	// Usage:
	//	event, err := GitlabRequestParser.Validate(r, secret)
	//	if err != nil {
	//		return
	//	}
	//	switch event := event.(type) {
	//	case gitlab.MergeCommentEvent:
	//		// handle
	//	case gitlab.MergeEvent:
	//		// handle
