### OAuth2.0流程：參照github （1）用戶訪問客戶端，后者將前者導向認證服務器： * response\_type：表示授權類型，必選項，此處的值固定為"code" * client\_id：表示客戶端的ID，必選項 * redirect\_uri：表示重定向URI，可選項 * scope：表示申請的權限范圍，可選項 * state：表示客戶端的當前狀態，可以指定任意值，認證服務器會原封不動地返回這個值。 https://gitee.com/oauth/authorize?client_id=xxx&redirect_uri=rediurl&response_type=code https://github.com/login/oauth/authorize?client_id=xxx&scope=user:email （2）認證服務器重定向到redirect_uri，并返回參數code （3）應用服務器獲取到code，并把賬號相關信息POST請求認證服務器 * client_id：用戶ID * client_secret：用戶秘鑰 * code：接收到的code碼 （4）認證服務器返回access_token，再次用得到的token請求 * github：access_token=021118b849fb88a68c805fd9c22699c4017xxx&scope=user%3Aemail&token_type=bearer （5）得到最終需要的數據： ``` { "login":"linzening", "id":29197457, "node_id":"MDQ6VXNlcjI5MTk3NDU3", "avatar_url":"https://avatars2.githubusercontent.com/u/29197457?v=4", "gravatar_id":"", "url":"https://api.github.com/users/linzening", "html_url":"https://github.com/linzening", "followers_url":"https://api.github.com/users/linzening/followers", "following_url":"https://api.github.com/users/linzening/following{/other_user}", "gists_url":"https://api.github.com/users/linzening/gists{/gist_id}", "starred_url":"https://api.github.com/users/linzening/starred{/owner}{/repo}", "subscriptions_url":"https://api.github.com/users/linzening/subscriptions", "organizations_url":"https://api.github.com/users/linzening/orgs", "repos_url":"https://api.github.com/users/linzening/repos", "events_url":"https://api.github.com/users/linzening/events{/privacy}", "received_events_url":"https://api.github.com/users/linzening/received_events", "type":"User", "site_admin":false, "name":"linzening", "company":null, "blog":"", "location":null, "email":null, "hireable":null, "bio":null, "public_repos":15, "public_gists":0, "followers":0, "following":1, "created_at":"2017-06-05T10:19:49Z", "updated_at":"2019-02-28T11:26:10Z" } ``` >[info] 參考文檔：`http://www.ruanyifeng.com/blog/2014/05/oauth_2_0.html`
