Library webhooks

Library webhooks allows for easy receiving and parsing of GitHub, Bitbucket and GitLab Webhook Events

Features:

• Parses the entire payload, not just a few fields.
• Fields + Schema directly lines up with webhook posted json

Notes:

• Currently only accepting json payloads.

Installation

Use go get.

	go get -u gopkg.in/go-playground/webhooks.v3

Then import the package into your own code.

import "gopkg.in/go-playground/webhooks.v3"

Usage and Documentation

Please see http://godoc.org/gopkg.in/go-playground/webhooks.v3 for detailed usage docs.

Examples:

Multiple Handlers for each event you subscribe to

package main

import (
	"fmt"
	"strconv"

	"gopkg.in/go-playground/webhooks.v3"
	"gopkg.in/go-playground/webhooks.v3/github"
)

const (
	path = "/webhooks"
	port = 3016
)

func main() {

	hook := github.New(&github.Config{Secret: "MyGitHubSuperSecretSecrect...?"})
	hook.RegisterEvents(HandleRelease, github.ReleaseEvent)
	hook.RegisterEvents(HandlePullRequest, github.PullRequestEvent)

	err := webhooks.Run(hook, ":"+strconv.Itoa(port), path)
	if err != nil {
		fmt.Println(err)
	}
}

// HandleRelease handles GitHub release events
func HandleRelease(payload interface{}, header webhooks.Header) {

	fmt.Println("Handling Release")

	pl := payload.(github.ReleasePayload)

	// only want to compile on full releases
	if pl.Release.Draft || pl.Release.Prelelease || pl.Release.TargetCommitish != "master" {
		return
	}

	// Do whatever you want from here...
	fmt.Printf("%+v", pl)
}

// HandlePullRequest handles GitHub pull_request events
func HandlePullRequest(payload interface{}, header webhooks.Header) {

	fmt.Println("Handling Pull Request")

	pl := payload.(github.PullRequestPayload)

	// Do whatever you want from here...
	fmt.Printf("%+v", pl)
}

Single receiver for events you subscribe to

package main

import (
	"fmt"
	"strconv"

	"gopkg.in/go-playground/webhooks.v3"
	"gopkg.in/go-playground/webhooks.v3/github"
)

const (
	path = "/webhooks"
	port = 3016
)

func main() {

	hook := github.New(&github.Config{Secret: "MyGitHubSuperSecretSecrect...?"})
	hook.RegisterEvents(HandleMultiple, github.ReleaseEvent, github.PullRequestEvent) // Add as many as you want

	err := webhooks.Run(hook, ":"+strconv.Itoa(port), path)
	if err != nil {
		fmt.Println(err)
	}
}

// HandleMultiple handles multiple GitHub events
func HandleMultiple(payload interface{}, header webhooks.Header) {

	fmt.Println("Handling Payload..")

	switch payload.(type) {

	case github.ReleasePayload:
		release := payload.(github.ReleasePayload)
		// Do whatever you want from here...
		fmt.Printf("%+v", release)

	case github.PullRequestPayload:
		pullRequest := payload.(github.PullRequestPayload)
		// Do whatever you want from here...
		fmt.Printf("%+v", pullRequest)
	}
}

Functions

func Run

func Run(hook Webhook, addr string, path string) error

Run runs a server

func RunServer

func RunServer(s *http.Server, hook Webhook, path string) error

RunServer runs a custom server.

func RunTLSServer

func RunTLSServer(s *http.Server, hook Webhook, path string) error

RunTLSServer runs a custom server with TLS configuration. NOTE: http.Server Handler will be overridden by this library, just set it to nil. Setting the Certificates can be done in the http.Server.TLSConfig.Certificates see example here: https://github.com/go-playground/webhooks/blob/v2/webhooks_test.go#L178

Types

type Header

type Header http.Header

Header provides http.Header to minimize imports

type ProcessPayloadFunc

type ProcessPayloadFunc func(payload interface{}, header Header)

ProcessPayloadFunc is a common function for payload return values

type Provider

type Provider int

Provider defines the type of webhook

const (
	GitHub Provider = iota
	Bitbucket
	GitLab
)

webhooks available providers

func (Provider) String

func (p Provider) String() string

type Webhook

type Webhook interface {
	Provider() Provider
	ParsePayload(w http.ResponseWriter, r *http.Request)
}

Webhook interface defines a webhook to receive events
