/*
Package lark provides message notification integration for Lark. Two kinds of
bots on Lark are supported -- webhooks and custom apps. For information on
webhook bots, see
https://open.larksuite.com/document/uAjLw4CM/ukTMukTMukTM/bot-v3/use-custom-bots-in-a-group,
and for info on custom apps, see
https://open.larksuite.com/document/home/develop-a-bot-in-5-minutes/create-an-app.

Usage:

  package main

  import (
    "context"
    "log"

    "github.com/nikoksr/notify"
    "github.com/nikoksr/notify/service/lark"
  )

  const (
    webhookURL = "https://open.feishu.cn/open-apis/bot/v2/hook/xxx"
    appId      = "xxx"
    appSecret  = "xxx"
  )

  func main() {
    // Two types of services are available depending on your requirements.
    larkWebhookService := lark.NewWebhookService(webhookURL)
    larkCustomAppService := lark.NewCustomAppService(appId, appSecret)

    // Lark implements five types of receiver IDs. You'll need to specify the
    // type using the respective helper functions when adding them as receivers
    // for the custom app service.
    larkCustomAppService.AddReceivers(
      lark.OpenID("xxx"),
      lark.UserID("xxx"),
      lark.UnionID("xxx"),
      lark.Email("xyz@example.com"),
      lark.ChatID("xxx"),
    )

    notifier := notify.New()
    notifier.UseServices(larkWebhookService, larkCustomAppService)

    if err := notifier.Send(context.Background(), "subject", "message"); err != nil {
      log.Fatalf("notifier.Send() failed: %s", err.Error())
    }

    log.Println("notification sent")
  }
