准备Lookup服务  
1、创建服务注册器：  
详细步骤查考： Create the Service Registration Filter and Retrieve the Registration Object。在下面将讲解如何使用Lookup服务注册器，请查考Introduction to Filters.  
2、检索服务注册对象：  
查考 Create the Service Registration Filter and Retrieve the Registration Object 和 Create the Service Registration Filter and Retrieve the Registration Object。  
3、连接Lookup服务  
查考 Connect to the Lookup Service。  
4、编写代码检索Lookup服务查询相关信息。  
参考：Options for Retrieving Information from the Lookup Service 显示可供你不同的选择。

图形结构已经描述的很清楚，在此不做翻译。

用你的身份验证凭据从vCenter单点登录服务或通过的vCloud端点获得令牌。  
查考：VMware vCenter Single Sign-On Service.  
通过SAML 令牌对服务端进行相关的请求操作。  
查考： Connections and Sessions.
