# Facebook 챗봇 만들기(Mac OS 기준)

## 1. Set up Your Environment (환경설정)

* 메신저 봇은 메시지를 받거나 전송하기 위해 웹서버를 이용한다.
* 봇이 웹서버와 대화할 수 있으려면 웹서버와 인증을 거쳐야 한다.
* 페이스북을 통해 대중과 대화하려면 페이스북의 승인절차도 필요하다.

### 1.1 Build the Server (서버구축)

* Heroku [가입](https://www.heroku.com)
* 로컬에 Heroku CLI [설치](https://devcenter.heroku.com/articles/heroku-cli)
* brew 로 Heroku CLI 설치시 오류나는 경우:

  ```
  Target /usr/local/bin/heroku
  already exists. You may want to remove it:
  rm '/usr/local/bin/heroku'..
  ```

  [여기](http://theoveranalyzed.net/2015/10/12/heroku-toolbelt-and-mac-os-x-1011-el-capitan) 참고.
* 서버코드 작성(index.js)

  \`\`\`javascript var express = require('express') var bodyParser = require('body-parser') var request = require('request') var app = express()

app.set('port', (process.env.PORT || 5000))

// Process application/x-www-form-urlencoded app.use(bodyParser.urlencoded({extended: false}))

// Process application/json app.use(bodyParser.json())

// Index route app.get('/', function (req, res) { res.send('Hello world, I am a chat bot') })

// for Facebook verification app.get('/webhook/', function (req, res) { if (req.query\['hub.verify\_token'] === 'my\_voice\_is\_my\_password\_verify\_me') { res.send(req.query\['hub.challenge']) } res.send('Error, wrong token') })

// Spin up the server app.listen(app.get('port'), function() { cons

```
* 서버 실행
```

node index.js running on port 5000

````
* 서버 테스트
```javascript
curl http://localhost:5000
Hello world, Im a chat bot
````

* Procfile 생성

  ```
  web: node index.js
  ```
* Heroku 로그인(터미널에서)

  ```
  heroku login
  ```
* git 커밋

  ```
  git init
  git add .
  git commit -m "first commit"
  heroku create
  git push heroku master
  ```
