要实现OAuth服务端,就得先理解客户端的调用流程,服务提供商实现可能也有些区别,实现OAuth服务端的方式不少,具体可能看 http://oauth.net/code/node
各语言的实现有(我使用了Apache Oltu):git
- Java
- NodeJS
- NodeJS OAuth 2.0 Provider
- Mozilla Firefox Accounts. A full stack Identy Provider system developed to support Firefox market place and other services
- Ruby
- .NET
实现主要涉及参数配置以下:
受权码设置(code)
第三方经过code进行获取 access_token的时候须要用到,code的超时时间为10分钟,一个code只能成功换取一次access_token即失效。
受权做用域(scope)
做用域表明用户受权给第三方的接口权限,第三方应用须要向服务端申请使用相应scope的权限后,通过用户受权,获取到相应access_token后方可对接口进行调用。
令牌有效期(access_token)
access_token是调用受权关系接口的调用凭证,因为access_token有效期(目前为2个小时)较短,当access_token超时后,能够使用refresh_token进行刷新,access_token刷新结果有两种:
1. 若access_token已超时,那么进行refresh_token会获取一个新的access_token,新的超时时间;
2. 若access_token未超时,那么进行refresh_token不会改变access_token,但超时时间会刷新,至关于续期access_token。
refresh_token拥有较长的有效期(30天),当refresh_token失效的后,须要用户从新受权。github
项目结构以下:
AuthzController:获取受权码
TokenController:得到令牌
ResourceController:资源服务
ClientController:客户端web
基础代码放到github:https://github.com/zhouyongtao/homeinns-webspring
确保项目8080端口运行,能够手动调试apache
得到受权码
http://localhost:8080/oauth2/authorize?client_id=fbed1d1b4b1449daa4bc49397cbe2350&response_type=code&redirect_uri=http://localhost:8080/oauth_callback
得到令牌(POST)
http://localhost:8080/oauth2/access_token?client_id=fbed1d1b4b1449daa4bc49397cbe2350&client_secret=fbed1d1b4b1449daa4bc49397cbe2350&grant_type=authorization_code&redirect_uri=http://localhost:8080/oauth_callback&code={code}json
也能够使用以下客户端测试代码,访问 http://localhost:8080/client 测试api
