一、设计理念
1.先写一个登录的py文件,用python的tkinter库
2.再写一个py文件用于爬取有道翻译输出栏的内容
3.再利用python的tkinter库,完成软件运行的窗口
4.将窗口的返回值与爬取有道翻译的结果接口对一下
5.第二个py文件里import第一个py文件,两个文件相关联
二、代码解析
请求方式为post,要注意from data里的值,这里可以在网页上再输一个想要翻译的内容,观察from data里的值的变化,可以确定'salt'、 ‘sign'、 'lts'这三个值变化
进入网页源代码搜索.js,找到对应的js文件,找到他们的加密规则,最后将获得的response转化为字典,提取结果

三、软件窗口界面
尤其注意按钮这个地方
self.button = Button(self.window, text=u'查询', command=self.function)
command命令执行function

function这块要把爬虫返回的值和窗口的翻译框做一下接口
