原文地址：http://bbs.seacat.cn/thread-898-1-1.html

Standard Query Parameters  标准化查询参数查询参数,适用于所有Google Mirror API的操作，如下表所示：

说明（API密钥和身份验证令牌）：


1.每个请求的关键参数都是必需的,除非你提供一个OAuth 2.0令牌的请求。
2.你必须为每个请求发送一个授权令牌用来被标记(身份验证)。OAuth 2.0是首选的授权协议。
3.您可以为任何请求提供一个OAuth 2.0令牌，可以用以下两种方式。
   ~使用 access_token 查询参数像这样:?access_token={oauth2-token}

 ~使用HTTP Authorization header像这样：Authorization: Bearer{oauth2-token}

除非特别声明,否则所有参数都是可选的。
