学习记录：百度翻译
👉1、目标网址
百度翻译：百度翻译-200种语言互译、沟通全世界！
👉2、接口分析调试
查看其参数：
初看感觉：sign 和 token 会变，多测试几次翻译后发现：sign 会变，但是输入相同的字符去请求翻译，携带的 sign 是同一个，对于 token ，它是一直没有变化的。那就先去解决token 试试，老办法，直接搜索它。
点击去找到它了：在首次进入页面的网页中：re 取出即可
https://fanyi.baidu.com/?aldtype=16047token：√
再去找 sign：搜到相关接口，点击进入查看
先不管其他的，直接进去ctr + f 搜索 sign
一直enter 我找到了两处可能是sign参数生成的地方：
1、
2、
对照前面网页请求的参数，发现他们都很可疑，这样的话，打上断点进行调试：
发现1图出才是我们想要的JS：
如下：
sign：√
主要的sign 定位到了，其他参数再慢慢测试即可：
👉3、python 代码实现
这里直接扣下JS，python调用实现加密，首先要有 node 环境，安装node.js 插件，pycharm专业版。我之前pycharm是社区版的。重新去安装一个专业版即可。

JS：
// 安装 node.js 插件 即可 右键运行
