阿里安全开放平台-阿里聚安全

本文介绍如何使用Alibaba Cloud SDK for Python将一个弹性公网IP EIP（Elastic IP Address）添加到共享带宽中。

前提条件

在使用Alibaba Cloud SDK for Python前，您需要完成以下准备工作：

您需要一个阿里云账号和访问密钥（AccessKey）。请在阿里云控制台中的AccessKey管理页面上创建和查看您的AccessKey。
确保您已经安装了Alibaba Cloud SDK for Python，请参见aliyun-python-sdk-vpc 3.0.12。
下载阿里云专有网络Python SDK场景示例的VPC Python Example库。
进入 setup.py所在的目录，执行以下命令，完成环境初始化配置。
```
python setup.py install
```

背景信息

本文代码示例中包含以下操作：

在华东1（杭州）地域创建一个EIP。
在华东1（杭州）地域创建共享带宽。
将新创建的EIP加入到共享带宽中。
查询共享带宽。
将EIP移出共享带宽。
删除共享带宽。
释放EIP。

操作步骤

在下载的SDK目录中，打开aliyun-openapi-python-sdk-examples\sdk_examples\examples\eip文件夹。

使用编辑器打开eip_add_cbwp.py文件，根据实际情况配置相关参数，保存退出。
