红帽全球峰会第 4 章 入口点
用户开始通过由 主机和 基础 组成的入口点 URI 上的
GET 请求与 API 交互。
例 4.1. 访问 API 条目点
如果主机是 www.example.com 且 基础 是 /ovirt-engine/api，则入口点会出现有以下请求：
GET /ovirt-engine/api HTTP/1.1
Accept: application/xml
Host: www.example.com
Authorization: [base64 encoded credentials]
HTTP/1.1 200 OK
Content-Type: application/xml
<api>
<link rel="hosts" href="/ovirt-engine/api/hosts"/>
<link rel="vms" href="/ovirt-engine/api/vms"/>
...
<product_info>
<name>Red Hat Virtualization</name>
<vendor>Red Hat</vendor>
<version revision="0" build="0" minor="0" major="4"/>
</product_info>
<special_objects>
<link rel="templates/blank" href="..."/>
<link rel="tags/root" href="..."/>
</special_objects>
<summary>
<vms>
<total>10</total>
<active>3</active>
</vms>
<hosts>
<total>2</total>
<active>2</active>
</hosts>
<users>
<total>8</total>
<active>2</active>
</users>
<storage_domains>
<total>2</total>
<active>2</active>
</storage_domains>
</summary>
</ovirt-engine/api>
注意
为简单起见，所有其他示例都省略
Host: 和 Authorization: 请求标头，并假定 base 是默认的 /ovirt-engine/api 路径。这个基础路径根据您的实施而有所不同。
4.1. 产品信息
复制链接链接已复制到粘贴板!
入口点包含一个
product_info 元素，用于帮助 API 用户决定 Red Hat Virtualization 环境的 legitimacy。这包括产品 的名称、vendor 和 version。
例 4.2. 验证 genuine Red Hat Virtualization 环境
以下元素标识了 Red Hat Virtualization 4.0 环境：
<api>

<full_version>4.0.2.3-0.1.el7ev</full_version>
<major>4</major>
<minor>0</minor>
<revision>0</revision>
</version>
</product_info>
