메신저 중에 하나로 텔레그램을 이용하고있습니다. 텔레그램은 장점이 매우 많습니다. 텔레그램은 Github(‘[email protected]:vysheng/tg.git’) 통해서 API 및 소스가 공개하고있습니다. 해당 자료 다운 받으시면 됩니다.

우선 텔레그램의 주요 특징과 장점들에 대해 간략하게 적었습니다.(이미 너무나 잘 알고있다면 스킵하셔도 좋습니다.)

1. **Private **(Telegram messages are heavily encrypted and can self-destruct.)
2. Cloud-Based (Telegram lets you access your messages from multiple devices.)
3. Fast (Telegram delivers messages faster than any other application.)
4. Distributed (Telegram servers are spread worldwide for security and speed.)
5. Open (Telegram has an open API and protocol free for everyone.)
6. 1. Free (Telegram is free forever. No ads. No subscription fees.)
7. **Secure **(Telegram keeps your messages safe from hacker attacks.)
8. **Powerful **(Telegram has no limits on the size of your media and chats.)

이 것 이외에도 프로그래머라면 디버깅할 때, 정말 도움이 많이 됩니다.

또한 cron설정을 통해서 주기적으로 스냅샷 정보 또는 서버 상태등을 피드백 받을수있어 더 좋습니다.

이러한 장점들을 보니 얼른 설치하고싶다구요? 저의 간략한 환경(Description: Ubuntu 14.04.2 LTS) 입니다. 따라하실때 참고하세요 ^^..

또 설치하기전에 가상번호를 이용하는 방법도있고 위에 말한 장점들을 사용할 때 계정을 이용하지아니하고 봇을 이용하는 방법이있는데, 본인은 봇을 이용하는 방법을 선택하겠다. 이 방법이 훨씬 간단하고 효율적일 것 같아서다. 봇 이용방법 이외 Cli를 통한 Telegram 사용방법도 기재할테니 Cli를 통한 사용법이 알고싶은 분들은 봇을 통한 이용방법 부분은 건너뛰시면 되겠습니다.

아래는 텔레그램 bot api 관련 페이지입니다. (https://core.telegram.org/bots/api)

봇에 대한 자세한 설명은 해당 링크(‘https://core.telegram.org/bots’)를 참조하시길 바랍니다.

BotFather을 통하여 나의 새로운 봇을 생성해준다. 설정을 완료하면 Api Token 값이 온다.

해당 값을 통해서 봇을 핸들링할수있다. BotFather의 간략한 명령어

• /newbot - create a new bot
• /token - generate authorization token
• /revoke - revoke bot access token
• /setname - change a bot’s name
• /setdescription - change bot description
• /setabouttext - change bot about info
• /setuserpic - change bot profile photo
• /setinline - change inline settings
• /setinlinefeedback - change inline feedback settings
• /setcommands - change bot commands list
• /setjoingroups - can your bot be added to groups?
• /setprivacy - what messages does your bot see in groups?
• /deletebot - delete a bot
• /cancel - cancel the current operation

Bot Api 에 기재된 내용들을 참고해서, 요청하면 된다.

자 그럼 이제 cli를 통한 사용법에 대해 알아봅시다.

우선 서버에 Telegram을 설치합시다.

소스 설치

git clone --recursive https://github.com/vysheng/tg.git 

빌드 툴 설치

apt-get install libreadline-dev libconfig-dev libssl-dev lua5.2 liblua5.2-dev libevent-dev libjansson-dev libpython-dev make 빌드 ./configure make

인증

연결할 핸드폰 번호를 입력하고, 해당 번호로 온 인증번호를 입력합니다. 그럼 정상적으로 로그인합니다.

그럼런 간단하게 다른 사람에게 메세지를 보내보도록합시다.

준호에게 메세지를 보냈습니다.

[05:20]  Jang Junho  msg Jang_Junho 테스트[05:20]  Jang Junho  msg Jang_Junho 테스트오호호오[05:20]  Jang Junho <<< 테스트오호호오

잘 되네요. 자신이 사용하는 사이드언어를 통해서 간단한 프로그램 만들어보세요.

위에서 말했듯이 텔레그램을 통해서 주기적인 서버상태 확인 과 명령어등을 통해서 핸들링할수있습니다. 다방면으로 아주 유용한 친구입니다.

아래 Telegram CLI 명령어들을 소개하고, 급하게 포스팅 마무리 짓 겠습니다. 바쁘다는 핑계로..ㅜㅜ 그럼 즐거운 플밍하십쇼.*(꾸벅)
