4、注意点
-
Fiddler安装及使用
抓包工具-fiddler出现“The system proxy was changed，click to reenable fiddler capture”的提示问题
我的解决方法是：安装了进学校内网的easyconnect，卸载之后，就没有“The system proxy was changed，click to reenable fiddler capture”的提示问题了使用fiddler对手机上的程序进行抓包
一步一步按教程来，手机先安装证书，再设置代理，前后顺序不要颠倒 -
模块调用方法
-
类内函数调用类内另一个函数的变量
（1）将该变量添加到self参考文章
（2）使用全局变量 global参考文章
-
由pytest中类初始化和方法初始化区别引发的思考
-
python问题
unindent does not match any outer indentation level在pycharm平台的解决方法这种情况一般是由于 缩进 参考文章
5、总结
代码封装的简洁性不够，其次因为时间仓促，这一部分只做了最后一节的练习题，有点遗憾的感觉。
