如何在Centos 7中设置OpenStack API配置？

请告诉我哪个SDK更适合调用OpenStack API

---

我没有找到关于这个主题的太多信息或教程。

如果您正在使用CLI；官方的Openstack客户端是显而易见的选择。如果您试图进行编程API调用，您可以使用任何东西，从简单的http请求到Python或Golang之类的客户端库

pip install openstacksdk

这是python代码吗？您可以指导我如何开发API，从外部服务器依次调用identity API和其他API。是的，您可以看到这是python代码，有关更多详细信息，请参阅完整的指南链接。thanksI在单独的虚拟机中使用openstack，我正试图通过本地主机的API调用调用这些openstack服务如何做到这一点请帮助我无论您在哪个虚拟机中运行opstack，只要在客户端配置中输入URL、用户和密码即可
