Python-01 Base64转换为Hex

Python-01 Base64转换为Hex

第一个python程序编写的小工具，提取网页xml文件中ECU key编码对应的base64字符串并将其转换为Hex格式的编码。优化GUI界面设计使其更加人性化的。

功能介绍：

1. 点击按钮“Open key xml file",选择加载需要待解析的xml key文件。

2. 点击按钮“Conversion"，实现Base64到Hex字符串的功能转换。

3. 点击按钮 "Open Key Txt"打开记录字符串编码转换的txt格式文件。Output Key file记录txt文件名以及存储在运行程序下的路径。

Python主程序源代码：

主程序需要引用以下第三方库，其中包含部分Python自带的库函数

BaseToHex.py

全局变量的定义文件

global_variant.py

global SerialNumber

global file_address

global Base64Excute

global Base64Write

global Base64Read

global HexExcute

global HexWrite

global HexRead

global ECUTemicNumber

global ECUSerialNumber

global filepath

以上为该程序的全部源代码。

关于UI界面设计出来之后，在不同分辨率的屏幕上面运行出现控件和字体变形状态。

可以通过设置“布局”—>“栅格布局(G)”来解决这个问题。设置之后，GUI界面被一体化，可以通过整体缩放。

最后，生成可执行程序.exe文件，运用cmd窗口pyinstaller指令生成。-w 用于不显示命令行窗体。

pyinstaller -F -w D:\Documents\Python\Base64ToHex.py

附加载解析的xml文件：
