# 설치 가이드

1. 코드 내려받기

git clone https://github.com/remixz/messenger-bot

깃허브에서 프로젝트 코드 전체를 내 컴퓨터로 내려받습니다.

cd messenger-bot

방금 내려받은 프로젝트 폴더 안으로 이동합니다.

2. Node.js

쉬움 추천

사전 준비물

Git GitHub에서 프로젝트 코드를 내려받으려면 필요합니다.
Node.js npm 명령어를 쓰려면 Node.js가 설치되어 있어야 합니다. LTS(장기지원) 버전을 추천합니다.

npm install messenger-bot

package.json에 명시된 라이브러리들을 내려받아 설치합니다.

✅ 명령어 실행 후 터미널에 나타나는 주소(보통 http://localhost:3000 형태)를 브라우저에서 열어보세요.

이 레포의 README에 적힌 실제 명령어를 그대로 가져왔습니다.

A Node client for the [Facebook Messenger Platform](https://developers.facebook.com/docs/messenger-platform).

Requires Node >=4.0.0.

## Installation

```bash
npm install messenger-bot
```

## Example

See more examples in [the examples folder.](https://github.com/remixz/messenger-bot/tree/master/example)

Run this example in the cloud: [![Nitrous Quickstart](https://nitrous-image-icons.s3.amazonaws.com/quickstart.svg)](https://www.nitrous.io/quickstart)
* Setup `PAGE_TOKEN`, `VERIFY_TOKEN`, `APP_SECRET` and start the example by `Run > Start Messenger Echo Bot`.
* Your Webhook URL is available at `Preview > 3000` in the IDE.

```js
const http = require('http')
const Bot = require('messenger-bot')

let bot = new Bot({
  token: 'PAGE_TOKEN',
  verify: 'VERIFY_TOKEN',
  app_secret: 'APP_SECRET'
})

bot.on('error', (err) => {
  console.log(err.message)
})

bot.on('message', (payload, reply) => {
  let text = payload.message.text

bot.getProfile(payload.sender.id, (err, profile) => {
    if (err) throw err

reply({ text }, (err) => {
      if (err) throw err

console.log(`Echoed back to ${profile.first_name} ${profile.last_name}: ${text}`)
    })
  })
})

http.createServer(bot.middleware()).listen(3000)
console.log('Echo bot server running at port 3000.')
```

## Usage

### Functions

#### `let bot = new Bot(opts)`

Returns a new Bot instance.

`opts` - Object

* `token` - String: Your Page Access Token, found in your App settings. Required.
* `verify` - String: A verification token for the first-time setup of your webhook. Optional, but will be required by Facebook when you first set up your webhook.
* `app_secret` - String: Your App Secret token used for message integrity check. If specified, every POST request  will be tested for spoofing. Optional.

#### `bot.middleware()`

The main middleware for your bot's webhook. Returns a function. Usage:

```js
const http = require('http')
const Bot = require('messenger-bot')

let bot = new Bot({
  token: 'PAGE_TOKEN',
  verify: 'VERIFY_TOKEN'
})

http.createServer(bot.middleware()).listen(3000)
```

As well, it mounts `/_status`, which will return `{"status": "ok"}` if the middleware is running. If `verify` is specified in the bot options, it will mount a handler for `GET` requests that verifies the webhook.

#### `bot.sendMessage(recipient, payload, [callback], [messagingType], [tag])`

Sends a message with the `payload` to the target `recipient`, and calls the callback if any. Returns a promise. See [Send API](https://developers.facebook.com/docs/messenger-platform/send-api-reference#request).

* `recipient` - Number: The Facebook ID of the intended recipient.
* `payload` - Object: The message payload. Should follow the [Send API format](https://developers.facebook.com/docs/messenger-platform/send-api-reference).
* `callback` - (Optional) Function: Called with `(err, info)` once the request has completed. `err` contains an error, if any, and `info` contains the response from Facebook, usually with the new message's ID.
* `messagingType` - (Optional) String: The message type. [Supported Messaging Type](https://developers.facebook.com/docs/messenger-platform/send-messages#messaging_types).
* `tag` - (Optional) String: The tag's message. [Supported Tags](https://developers.facebook.com/docs/messenger-platform/send-messages/message-tags#supported_tags).

#### `bot.getAttachmentUploadId(url, is_reusable, type, [callback])`

Sends the media to the Attachment Upload API and calls the callback if the upload is successful, including the `attachment_id`. See [Attachment Upload API](https://developers.facebook.com/docs/messenger-platform/reference/attachment-upload-api).

* `url` - String: Link where can be fetched the media.
* `is_reusable` - Boolean: Defined if the saved asset will be sendable to other message recipients.
* `type` - String: The type of media. Can be one of: `image`, `video`, `audio`, `file`.
* `callback` - (Optional) Function: Called with `(err, info)` once the request has completed. `err` contains an error, if any, and `info` contains the response from Facebook, usually with the media's ID.

#### `bot.sendSenderAction(recipient, senderAction, [callback])`

Sends the sender action `senderAction` to the target `recipient`, and calls the callback if any. Returns a promise.

* `recipient` - Number: The Facebook ID of the intended recipient.
* `senderAction` - String: The sender action to execute. Can be one of: `typing_on`, 'typing_off', 'mark_seen'. See the [Sender Actions API reference](https://developers.facebook.com/docs/messenger-platform/send-api-reference/sender-actions) for more information.
* `callback` - (Optional) Function: Called with `(err, info)` once the request has completed. `err` contains an error, if any, and `info` contains the response from Facebook, usually with the new message's ID.

#### `bot.unlinkAccount(psid, [callback])`

Unlinks the user with the corresponding `psid`, and calls the callback if any. Returns a promise. See [Account Unlink Endpoint].(https://developers.facebook.com/docs/messenger-platform/identity/account-linking?locale=en_US#unlink)

* `psid` - Number: The Facebook ID of the user who has to be logged out.
* `callback` - (Optional) Function: Called with `(err, info)` once the request has completed. `err` contains an error, if any, and `info` contains the response from Facebook.

#### `bot.setGetStartedButton(payload, [callback])`
#### `bot.setPersistentMenu(payload, [callback])`

Sets settings for the Get Started Button / Persistent Menu. See the [Messenger Profile Reference](https://developers.facebook.com/docs/messenger-platform/messenger-profile) for what to put in the `payload`.

#### `bot.removeGetStartedButton([callback])`
#### `bot.removePersistentMenu([callback])`

Removes the Get Started Button / Persistent Menu.

#### `bot.getProfile(target, [callback])`

Returns a promise of the profile information of the `target`, also called in the `callback` if any. See [User Profile API](https://developers.facebook.com/docs/messenger-platform/send-api-reference#user_profile_request).

* `target` - Number: The Facebook ID of the intended target.
* `callback` - (Optional) Function: Called with `(err, profile)` once the request has completed. `err` contains an error, if any, and `info` contains the response from Facebook, in this format:

```json
{
  "first_name": "Zach",
  "last_name": "Bruggeman",
  "profile_pic": "<url to profile picture>",
  "locale": "en",
  "timezone": "PST",
  "gender": "M"
}
```

#### `bot._handleMessage(payload)`

The underlying method used by `bot.middleware()` to parse the message payload, and fire the appropriate events. Use this if you've already implemented your own middleware or route handlers to receive the webhook request, and just want to fire the events on the bot instance. See [the echo bot implemented in Express](https://github.com/remixz/messenger-bot/blob/master/example/echo-express.js) for an example.

* `payload` - Object: The payload sent by Facebook to the webhook.

#### `bot._verify(req, res)`

The underlying method used by `bot.middleware()` for the initial webhook verification. Use this if you've already implemented your own middleware or route handlers, and wish to handle the request without implementing `bot.middleware()`. See [the echo bot implemented in Express](https://github.com/remixz/messenger-bot/blob/master/example/echo-express.js) for an example.

* `req` - Request: The `http` request object.
* `res` - Response: The `http` response object.
