If you do not want cell a to trust cell b, use certificate authentication for the server to server authentication step, not basic auth.

如果不希望计算单元a信任计算单元b，则请在服务器身份验证步骤中为服务器使用证书身份验证，而不是采用基本身份验证。

The "Call" object allows you to set HTTP user ID and password for basic auth, and also similar methods to cater for intermediate HTTP proxies, if they exist.

“Call”对象允许您为基本认证设置 HTTP 用户标识和密码，以及中间 HTTP 代理（如果它们存在的话）所需的类似方法。

尽管Basic Auth使用起来很简单，但是在HTTP传输过程中用户名和密码不受保护，所以此文章中不予讨论。
