由於自己管理的雲伺服器數量比較多，時不時需要更換IP，在管理臺上一下下點選，實在浪費時間，於是就想到了通過API呼叫的方式，將更換IP一系列動作，全部整合到Python程式碼裡面，實現一行命令，完成IP更換，由於人懶，就先

把最核心的程式碼（雖然都是騰訊雲生成的）、流程、坑點貼出來，僅供菜鳥參考，高手無視！已先在騰訊雲社群編輯釋出，請管理員勿認為是轉載！

具體步驟：

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

頁面左側列表查詢“私有網路”---“彈性公網相關介面”，就可以看到對應介面的文件了

二 選擇一個介面，然後點選“API 3.0 Exploper”，進入到開發者工具頁面，

坑點一：下面程式碼，對於菜鳥來說，引入的相關模組直接用“pip install 對應模組名”會報錯

看第一張圖sdk，相關語言sdk，點選就可以看到github上各語言的庫引用方式

三 直接copy開發者工具上的程式碼，當然你也可以看下圖程式碼

坑點二："SecretId ","SecretKey" 這兩個值是你呼叫API，騰訊用來確認你身份的憑證，

在哪裡申請呢？騰訊雲的首頁，“雲產品”--“管理工具”--“雲API祕鑰”，

沒有使用過的話，是不會在你的控制檯上顯示的。

坑點三：由於騰訊雲API文件的不合理，導致生成的程式碼有一些坑，

具體坑資訊我已在程式碼裡通過註釋的方式解釋了
