③ 여기에서 로컬 작업. apex를 설치하고 작업 디렉토리를 파십시오.

### apexインストール
$ curl https://raw.githubusercontent.com/apex/apex/master/install.sh | sh
$ mkdir apex-sample-go
$ cd apex-sample-go

### ~/.aws/configは。。設定してると思うからスルーするね！

### init
$ go get github.com/apex/go-apex
$ apex init

            / \  |  _ \| ____\ \/ /

  Enter the name of your project. It should be machine-friendly, as this
  is used to prefix your functions in Lambda.

    Project name: apex-sample-golang

  Enter an optional description of your project.

    Project description: apex-samle-golang

  [+] creating IAM apex-sample-golang_lambda_function role
  [+] creating IAM apex-sample-golang_lambda_logs policy
  [+] attaching policy to lambda_function role.
  [+] creating ./project.json
  [+] creating ./functions

  Setup complete, deploy those functions!

    $ apex deploy

### 確認

④ 통지용 프로그램 작성

$ tree

└── project.json

main.go

package main

import (
    "encoding/json"

    "github.com/apex/go-apex"
)

type message struct {
    Hello string `json:"hello"`
}

func main() {
    apex.HandleFunc(func(event json.RawMessage, ctx *apex.Context) (interface{}, error) {
        Run()

        return nil, nil
    })
}

run.go (채널 이름을 편집하십시오)

package main

import (

    "net/url"
)

type Slack struct {
    Text      string `json:"text"`
    Username  string `json:"username"`
    IconEmoji string `json:"icon_emoji"`

    Channel   string `json:"channel"`
}

func LoadSlackParam() *Slack {
    return &Slack{
        Text:      "testだよ！",
        Username:  "test",
        IconEmoji: ":bow:",
        IconURL:   "",
        Channel:   "チャンネル名書いてね",
    }
}

func Run()  {
    URL := "https://hooks.slack.com/services/xxxxxx/xxxxx/xxxxxxxxxxxxxxxxx"
    params, _ := json.Marshal(LoadSlackParam())

    resp, _ := http.PostForm(
        URL,
        url.Values{"payload": {string(params)}},
    )

    defer resp.Body.Close()
}

⑤deploy한다

$ apex deploy
# deployが終わった、lambdaでapex-sample-golang_hello関数ができてるはずです

⑥ 실행해 본다

### apexで掘ったディレクトリ内であれば
$ apex invoke hello

### aws cli経由であれば
$ aws lambda invoke --function-name apex-sample-golang_hello --invocation-type Event outputfile.txt

⑦ 삭제할 때는?

### apexから削除
$ apex delete
yes
# ウェブコンソールから削除しても良いです

### コンソール上でIAMから下記を削除
使ったPolicy
使ったrole
