使用curl调试openstack的api

一系统环境

OpenStack： Mitaka

工具：最简单的工具：restclient，本次使用curl

二开搞

访问openstack的API之前，用户使用用户名和密码向keystone进行认证。在通过keystone认证后，keystone会在返回数据中包含一个ServiceCatalog。此ServiceCatalog中包含keystone中的所有service endpoints。用户即可根据这些endpoint来进行后续的RestAPI调用。

本文主要示例如何调用V3版本API。对于V2版本，使用openstack命令加--debug参数，可以看到keystone调用curl的具体写法：

如果不知道该怎么取调用可以使用--debug查看
