本章包括以下主题：
■ 5.1 vCenter 服务器连接 ■ 5.2 与 vCenter 服务器建立一个单点登录会话 ■ 5.3 使用用户名和密码凭证建立一个会话 ■ 5.4 Web 服务器会话令牌 ■ 5.5 vSphere API 的多个版本 ■ 5.6 标识由服务器支持的API版本 ■ 5.7 Sample 应用程序
接前篇从第3节开始
你可以指定用户名和密码凭证来建立一个与 vCenter 服务器的会话，但是用这种方式来建立会话的方法已被 vSphere 5.1 弃用。 下列步骤描述了客户端应用是如何指定用户名和密码凭证访问 vCenter 服务器的。
创建一个到 vSphere server web 服务的连接；
实例化一个用于引用 ServiceInstance 的本地代理对象，使用该代理对象从服务器获取 ServiceContent 对象。ServiceContent 包含对清单的 root folder 的引用，以及对提供vSphere 服务的托管对象的引用；
实例化一个用于访问 vSphere 服务的本地代理对象；
使用恰当的凭证（用户名、密码等）登录服务器；
访问服务器端对象获取数据并执行管理操作；
关闭连接
下面直接给出客户端应用测试代码
