使用Python指令碼替換模板檔案中的版本號！

後端模板檔案引用前端資源，發布時，使用python指令碼自動替換前端資源的版本。

前端使用webpack構建，每次構建完成時，會生成乙個buildfile.json

buildfile.json

word 模板替換 poi tl簡單使用

工作中，需要給word 中的一些標籤替換為 指定的資料 暫時來記錄一下，並且網上找了一些 經典的 poi,itext 等,順便找了幾個比較好用的 嘗試使用了下並記錄下來poi tl 簡介 輕量，主要針對word的模板引擎，提供了對word的豐富操作。官網 其實官網很詳細了，自己就照搬一下吧。pomc...

使用Python指令碼批量替換專案中的資料庫位址

這幾天接手到了乙個很老很老的專案，php的，裡面的資料庫位址不是同一配置的。有很多子站點，每個字站點又有自己的配置檔案，這個時候，問題來了，要換資料庫位址了！初聞這個問題，我整個人都是懵逼的，這不是搞我嘛？這麼多改起來得多麻煩？但活兒還是得做啊，於是作為一名機智的大彩筆，我決定寫個python指令碼...
