目前 OpenStack中消息传递有两种机制，一种是消息队列，另一种就是Restful API。其中OpenStack项目的接口遵循REST原则，即使用Restful Api实现OpenStack各Server与Client交互通信。下面测试一下直接使用OpenStack中Restful API去实现相应的功能。Postman是一款前端调用工具，本文采用该工具来测试后端的接口。

1. keytone get-token

token是环境可操作的前提，OpenStack登陆时填写的用户名+密码，登陆之后的操作都是使用token。下面使用postman工具测试keystone服务的接口，尝试向keystone服务的endpoint地址发送携带用户名及用户名密码的POST请求，具体要求如下：

若发送POST请求后传入的用户名密码参数验证通过，则返回状态信息200，并成功获取token数据。

从上述截图返回的body信息来看，除了获取到认证的token外，并且获取到了Openstack全部服务的请求地址，详见下面"serviceCatalog"字段，后续将可以拿着该token去访问Openstack其他服务，如：nova、glance。

2. nova get server-list

下面用上述拿到的token和nova服务的endpoint信息来查询admin租户下的全部虚机。

填写Postman，填写的内容有4个点，分别是：
1.请求类型：GET。
2.请求的URL地址：/servers。
3.设置访问的header，这里是设置token的key。第一步已经获取了token的值，剩余的访问都是使用token处理。
4.设置token的值。

可知上图返回的body信息中查询到一台“wy”虚机。更多有关nova的操作，可参看官方文档中nova服务的API的描述，从API使用手册中进入Compute API（https://developer.openstack.org/api-ref/compute/）。下面给出一些nova server的操作请求地址：
