3.1.2. 重定向端点（3.1.2. Redirection Endpoint）

3.1.2. 重定向端点

在完成与资源所有者的交互后，授权服务器引导资源所有者的用户代理返回到客户端。授权服务器重定向用户代理至客户端的重定向端点，该端点是事先在客户端注册过程中或者当发起授权请求时与授权服务器建立的。

重定向端点URI必须是如RFC3986的3.4节所述的绝对URI。端点URI可以包含“application/x-www-form-urlencoded”格式（按附录B）的查询部分（RFC3986的3.4节），当添加额外的查询参数时必须保留该部分。端点URI不得包含片段部分。

3.1.2. Redirection Endpoint

   After completing its interaction with the resource owner, the
   authorization server directs the resource owner's user-agent back to
   the client.  The authorization server redirects the user-agent to the
   client's redirection endpoint previously established with the
   authorization server during the client registration process or when
   making the authorization request.

   The redirection endpoint URI MUST be an absolute URI as defined by
   [RFC3986] Section 4.3.  The endpoint URI MAY include an
   "application/x-www-form-urlencoded" formatted (per Appendix B) query
   component ([RFC3986] Section 3.4), which MUST be retained when adding
   additional query parameters.  The endpoint URI MUST NOT include a
   fragment component.
