Using google api in go

  1. 1. Using Google API in GoApr 20, 2013Jongmin KimGDG Korea Golang
  2. 2. 차례 OAuth API console, API explorer 등의 도구들 Keys, access, security, and identity Google API를 사용하기 위한 패키지들 Web applications 인증 데모 Service accounts 인증 데모 Google APIs Directory Service Google Auth Proxy by Bitly
  3. 3. OAuth 1.0aAtoiain Ouhram"tp/aigol.o/, uhrzto: At el=ht:/p.ogecm" ouhcnue_e=08b98jh2" at_osmrky"65d14fq2, ouhtkn"d8jd3kr7, at_oe=a10j73lu" ouhsgauemto=HA-H1, at_intr_ehd"MCSA" ouhsgaue"OI925FDivbSK2P%D, at_intr=wJOAWmwgDZTM%FY3" ouhtmsap"3110" at_ietm=17320, ouhnne"521e81dd52c1816, at_oc=476646666746667" ouhvrin"." at_eso=10 HMAC을 이용한 암호화 인증 방식만 제공 매번 signature를 생성해야 함 curl 등으로 테스트해보기 어려움 기본적으로 3-legged 모델
  4. 4. OAuth 2.0 3-legged 뿐만 아니라 2-legged 모델도 지원 아직 draft 버전 31. Google은 22 구현. Facebook은 12 구현 Client(1.0a에서 Consumer)는 Public Client와 Confidential Client로 크게 나뉨 명칭이 아래처럼 바뀜10 .a 20 .Ue sr → Rsuc Onr eore weCnue osmr → Cin letSriePoie evc rvdr → AtoiainSre +Rsuc Sre uhrzto evr eore evr Authorization Server와 Resource Server는 분리 가능
  5. 5. OAuth Service Providers KTH 개발자 블로그(http://dev.kthcorp.com/2012/12/12/oauth-2-0-open-api-auth/)
  6. 6. Useful Tools API console (https://code.google.com/apis/console/?pli=1#project:474377512137) OAuth 2.0 Playground (https://developers.google.com/oauthplayground/) APIs Explorer (https://developers.google.com/apis-explorer/#s/) Ajax Code Playground (https://code.google.com/apis/ajax/playground/) Authorized Access to your Google Account (https://accounts.google.com/b/0/IssuedAuthSubTokens)
  7. 7. Keys, access, security, and identityThe APIs represented in the Google APIs Console require that requests include aunique project identifier. This enables the Console to tie a request to a specific projectin order to monitor traffic, enforce quotas, and handle billing. Google supports twoseparate mechanisms to create a unique project identifier: OAuth 2.0 client IDs and APIkeys. OAuth 2.0 client ID API key
  8. 8. OAuth 2.0 client IDclient ID를 만들 수 있는 종류와 Google이 지원하는 OAuth 2.0 시나리오 Web application: Login, Web Server Applications, Client-side Applications Service account: Service Accounts Installed application: Installed Applications, Devices
  9. 9. API key 모든 API 호출 시, 파라미터로 key={API_key}를 붙여준다. 유저의 동의를 받지 않기 때문에 계정 정보에 접근하지는 못 한다. 인가(authorization)을 위해 사용되는 것은 아니다.
  10. 10. 필요 패키지들OAuth 2.0 패키지 $g gtcd.ogecmpgat2 o e oegol.o//ouhGoogle APIs Client Library for Go $g gtcd.ogecmpgol-p-ocin o e oegol.o//ogeaig-let다른 언어용 라이브러리들은 여기(https://developers.google.com/discovery/libraries) 참고
