腾讯云API弹性公网IP踩坑

由于自己管理的云服务器数量比较多，时不时需要更换IP，在管理台上一下下点击，实在浪费时间，于是就想到了通过API调用的方式，将更换IP一系列动作，全部集成到Python代码里面，实现一行命令，完成IP更换，由于人懒，就先

把最核心的代码（虽然都是腾讯云生成的）、流程、坑点贴出来，仅供菜鸟参考，高手无视！已先在腾讯云社区编辑发布，请管理员勿认为是转载！

具体步骤：

一 进入 https://cloud.tencent.com/document/api ，

页面左侧列表查找“私有网络”---“弹性公网相关接口”，就可以看到对应接口的文档了

二 选择一个接口，然后点击“API 3.0 Exploper”，进入到开发者工具页面，

坑点一：下面代码，对于菜鸟来说，引入的相关模块直接用“pip install 对应模块名”会报错

看第一张图sdk，相关语言sdk，点击就可以看到github上各语言的库引用方式

三 直接copy开发者工具上的代码，当然你也可以看下图代码

坑点二："SecretId ","SecretKey" 这两个值是你调用API，腾讯用来确认你身份的凭证，

在哪里申请呢？腾讯云的首页，“云产品”--“管理工具”--“云API秘钥”，

没有使用过的话，是不会在你的控制台上显示的。

坑点三：由于腾讯云API文档的不合理，导致生成的代码有一些坑，

具体坑信息我已在代码里通过注释的方式解释了

创建了一个微信群，目前看来是纯技术，虽然大家技术都不咋样，欢迎菜鸟或大牛的加入，目前看来还能算是个纯技术的讨论群，勿培训，勿卖视频
