关于用python3 制作google 翻译API的尝试 附上完整代码 （mac下能拼读单词）

}
首先是我构造的头请求部分
然后通过urllib.request.Request(url)构造完成
然后构造URL 部分
如果直接用浏览器显示的url的话
word = input(">> Search > ")
google = "http://translate.google.com/#auto/zh-CN/"
ps:cn和com都试过
编码没有问题，直接正则表达式提取编码
单返回的结果网页中却没有翻译的结果
只有一个空的<span id=result_box ></span> ps：<span id=result_box ...>...</span> 中有最关键的翻译结果
所以先用burpsuite 抓个包
发现
目前可以用的URl是
Request URL:http://translate.google.cn/translate_a/t?client=t&sl=en&tl=zh-CN&hl=en&sc=2&ie=UTF-8&oe=UTF-8&prev=btn&rom=1&ssel=0&tsel=0&q=这里放需要查询的单词
Request URL:http://translate.google.cn/translate_a/t?client=t&sl=auto&tl=zh-CN&hl=zh-CN&sc=2&ie=UTF-8&oe=UTF-8&uptl=zh-CN&alttl=en&oc=3&prev=enter&ssel=3&tsel=0&q=这里放查询的单词
然后记得用用结果的头信息解析即可得到结果
Mac下的我增加了 声音模块，其实很简单，用 say 指令即可
