1.1. 角色（1.1. Roles）

OAuth定义了四种角色：

• 资源所有者

  能够许可对受保护资源的访问权限的实体。当资源所有者是个人时，它被称为最终用户。

• 资源服务器

  托管受保护资源的服务器，能够接收和响应使用访问令牌对受保护资源的请求。

• 客户端

  使用资源所有者的授权代表资源所有者发起对受保护资源的请求的应用程序。术语“客户端”并非特指任何特定的的实现特点（例如：应用程序是否是在服务器、台式机或其他设备上执行）。

• 授权服务器

  在成功验证资源所有者且获得授权后颁发访问令牌给客户端的服务器。

授权服务器和资源服务器之间的交互超出了本规范的范围。授权服务器可以和资源服务器是同一台服务器，也可以是分离的个体。一个授权服务器可以颁发被多个资源服务器接受的访问令牌。

 

1.1. Roles

   OAuth defines four roles:

   resource owner
      An entity capable of granting access to a protected resource.
      When the resource owner is a person, it is referred to as an
      end-user.

   resource server
      The server hosting the protected resources, capable of accepting
      and responding to protected resource requests using access tokens.

   client
      An application making protected resource requests on behalf of the
      resource owner and with its authorization.  The term "client" does
      not imply any particular implementation characteristics (e.g.,
      whether the application executes on a server, a desktop, or other
      devices).

   authorization server
      The server issuing access tokens to the client after successfully
      authenticating the resource owner and obtaining authorization.

   The interaction between the authorization server and resource server
   is beyond the scope of this specification.  The authorization server
   may be the same server as the resource server or a separate entity.
   A single authorization server may issue access tokens accepted by
   multiple resource servers.
