花了兩天時間，寫好乙個指令碼，在樹莓pi 啟動的時候，自動傳送郵件通知，並且在後台獲得公網ip，通過郵件通知。
**測試完成。
接著想要，加入日誌，以及改進郵件傳送的過程。
先上原始碼吧。

C 獲取公網ip位址

python 3 爬蟲獲取可用ip位址（小白）
前幾天剛剛把正規表示式看了一些，也是只是稍微懂了一點點，所以想要寫乙個簡單的程式試一下。然後就想到了以前在找免費的 的時候有好多不能用的，所以就嘗試著寫了乙個這樣的爬蟲程式，寫的不是很好，寫的很複雜，等以後再去寫簡潔一些吧。先直接把 弄上，然後再說一下裡面的重點內容。import re import...
日誌獲取公網Ip以及內網穿透
檢視是不是那裡出了問題。要想解決這個問題，就要先找到那些地方插入ip,插入時是怎麼獲取的。順藤摸瓜，找到了getip 這個方法，進入原始方法檢視，發現方法是httpcontext.class中提供的，但是不知道為什麼不生效。於是我決定改變策略，不如自己寫乙個工具類，提供getaddress 獲取公網...
