实现 OAuth2.0 服务端

要实现OAuth服务端，我觉的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服务端的方式很多，具体可能看 http://oauth.net/code/

各语言的实现有(我使用了Apache Oltu):

  • Java
    • Apache Oltu
    • Spring Security for OAuth
    • Apis Authorization Server (v2-31)
    • Restlet Framework (draft 30)
    • Apache CXF
  • 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
    • Ruby OAuth2 Server (draft 18)
  • .NET
    • .NET DotNetOpenAuth
    • Thinktecture IdentityServer

    • 实现主要涉及参数配置如下:
    授权码设置(code)
    第三方通过code进行获取 access_token的时候需要用到，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。
    授权作用域(scope)
    作用域代表用户授权给第三方的接口权限，第三方应用需要向服务端申请使用相应scope的权限后，经过用户授权，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是调用授权关系接口的调用凭证，由于access_token有效期（目前为2个小时）较短，当access_token超时后，可以使用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，相当于续期access_token。
    refresh_token拥有较长的有效期（30天），当refresh_token失效的后，需要用户重新授权。

    请求授权码
