OAuth Core 1.0 Final in Chinese

The OAuth protocol enables websites or applications (Consumers) to access Protected Resources from a web service (Service Provider) via an API, without requiring Users to disclose their Service Provider credentials to the Consumers. More generally, OAuth creates a freely-implementable and generic methodology for API authentication.

OAuth协议致力于使网站和应用程序（统称为消费方）能够在无须用户透露其认证证书（译注：如登录密码）的情况下，通过API访问某个web服务（统称为服务提供方）的受保护资源。更一般地说，OAuth为API认证提供了一个可自由实现且通用的方法。
