告别网页搜索!教你用python实现一款属于自己的翻译词典软件

时间：2022-09-12 17:43:52

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

        result_str = response.read().decode('utf-8')
        result_dict = json.loads(result_str)
        result = result_dict["translateResult"][0][0]["tgt"]
        return result

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

class Application(object):
    def __init__(self):
        # 创建一个窗口
        self.window = Tk()
        # 窗口标题
        self.window.title(u'武亮宇翻译词典')
        # 设置窗口大小位置
        self.window.geometry("280x350+400+150")
        # 输入框
        self.entry = Entry(self.window)
        self.entry.place(x=10, y=10, width=200, height=25)  # width=宽度, height=高度
        # 查询按钮
        self.button = Button(self.window, text=u'查询', command=self.function)        # command执行命令的意思 执行这个函数
        self.button.place(x=220, y=10, width=50, height=25)
        # 翻译结果标题
        self.label = Label(self.window, text=u'翻译结果：')
        self.label.place(x=10, y=45)
        # 翻译框
        self.text = Text(self.window, background='#ccc')           # 设置背景颜色
        self.text.place(x=10, y=75, width=260, height=265)

function这块要把爬虫返回的值和窗口的翻译框做一下接口

def function(self):
        # 从输入框中获取用户的值
        content = self.entry.get()
        # 把值发送给有道服务器进行翻译
        youdao = YouDao()
        result = youdao.crawl(content)
        # 把结果放在翻译框里
        self.text.delete(1.0, END)      # 每次查询先删除一下
        self.text.insert(END, result)   # 插入文本最后的位置 导入END库
