只要在文本编辑器中编写好该
XML
文档，就可以将其复制并粘贴到交互式
NETCONF
会
话中。
粘贴完成之后，就可以看到成功的响应信息了。

之前已经说过好几次，但是我们打算再啰唆一次，因为这实在太重要了。当
你开始使用
NETCONF API
（或
RESTful API
）时，要注意如何构建正确的
请求对象。对新手而言，这通常不是件容易事，不过好在有一些省事的方法
可以帮你弄清楚如何构建这些对象。这可能来自
API
文档、处理底层模式定
义文件（比如
XSD
或
YANG
模块）的工具，甚至是设备上的
CLI
命令。例
如，
Cisco Nexus
和
Juniper Junos
的
CLI
命令可以准确地告诉你一个给定的
请求需要什么样的
XML
文档。你很快就能见到。
到此，本章已经回顾和探究了基于
HTTP
的
API
和
NETCONF
，你必须理解如何使用
这些
API
来自动化网络设备
。下面就来看看如何使用
Python
，通过基于
HTTP
的
API
、
NETCONF
和
SSH
来实现设备自动化。

实现自动化
正如我们所言，用于

和
学习

用法的工具和
API
应用工具是有区别的，后者更符合
生产操作模型。到目前为止，本章不仅介绍了
