【已解决】Mac中Chrome抓包分析google翻译请求的参数和逻辑

折腾:
【未解决】Python中寻找和使用在线翻译服务翻译中文为英文
期间,去mac中抓包分析一下google翻译的逻辑。
Google 翻译
此处,需要抓包模拟请求和提取结果
以及期间还要用上此处的本地的ssr的代理,否则不翻墙没法访问
抓包到请求了:

返回的json格式化:

然后去尝试写代码模拟,看看能否获取到翻译结果
对于请求的url:
https://translate.google.cn/translate_a/single?client=webapp&sl=zh-CN&tl=en&hl=zh-CN&dt=at&dt=bd&dt=ex&dt=ld&dt=md&dt=qca&dt=rw&dt=rm&dt=ss&dt=t&pc=1&otf=1&ssel=0&tsel=0&kc=1&tk=73822.494967&q=%E8%A3%85%E4%BF%AE%20PVC%20%E5%AE%B6%E7%94%A8%20%E6%A9%A1%E8%83%B6%E5%9C%B0%E6%9D%BF%20%E5%9C%B0%E6%9D%BF%E9%9D%A9
用postman去帮忙分割参数:
看起来参数是:
  • 核心参数
    • sl=zh-CN
      • sl估计是source language
    • tl=en
      • tl估计是 translate/translated language
    • q=%E8%A3%85%E4%BF%AE%20PVC%20%E5%AE%B6%E7%94%A8%20%E6%A9%A1%E8%83%B6%E5%9C%B0%E6%9D%BF%20%E5%9C%B0%E6%9D%BF%E9%9D%A9
  • 其他参数
    • client=webapp
    • hl=zh-CN
      • human language?
      • 不知道是否需要
    • pc=1
    • otf=1
关于:
%E8%A3%85%E4%BF%AE%20PVC%20%E5%AE%B6%E7%94%A8%20%E6%A9%A1%E8%83%B6%E5%9C%B0%E6%9D%BF%20%E5%9C%B0%E6%9D%BF%E9%9D%A9
估计是原始中文的utf-8编码
后来发现不是
utf-8解码
而是url解码
在线url网址编码、解码-BeJSON.com
