2.19 调用百度API 实现简易的翻译器

实现原理

tkinter 设计图形交互界面

在百度开发者平台申请权限 获得 appid 密钥

为保证安全 要使用 sign签名:使用md5算法 生成的一段字符串 生成的签名长度为32位 英文字符均为小写格式

签名生成的方法:

将请求参数中的 aappid+query(q,注意为'utf-8'编码)+salt(随机数)+密钥 得到字符串l

再将 l做md5 得到32位小写的sign

注意:

1.先将需要翻译的文本转换为'utf-8'编码

2.在发送HTTP请求前对各字段做URL encode

3.在生成签名拼接字符串时 q不用做URL encode 在生成签名之后发送HTTP 之前才需要对要发送的待翻译文本q做URL encode

有点写麻了的kimoji…

清空Entry 输入框 Entry1.delete(0,'end')

注意其中 html库 建立请求的方法

注意 string.decode('utf-8')

注意json.loads()将xxx格式转换为str的应用！！！
