输入要翻译的内容时 ， 地址并未发生变化，因此可断定是向接口发送的ajax请求
清空一下审查窗口，再点击一次翻译可以发现实际发送请求的url为https://fanyi.qq.com/api/translate
并且可以看到发送的是post请求，请求表单数据和响应数据都可以找到，复制form表单数据，然后换一个词翻译，同样复制form表单数据，比较两个表单数据有哪些不同，以方便去模仿构造数据
Form Data
source: auto
target: en
sourceText: 大象
qtv: fb7019db18d2efd2
qtk: tMDoh4iZnYF7a6MshJPtOvA7vXOMj0j+MUFcj6Ogl94MkIim6UUYl/KC4sv03GvVBnb2t6BbmOnew9ASvvKDh+sjJh7tOjLhy1W1M/S/xofJ469ZnMym2es4NJ2Ux8q3pZ0r/RCLPOPc15BSupGOcQ==
sessionUuid: translate_uuid1542022141842Form Data

sessionUuid: translate_uuid1542022664896可以看到 表单不同处只是输入的关键词和sessionUuid，看uuid后面的数字不知道是啥，有点像时间戳，去站长之家的工具箱搜了一下确实是毫秒制的时间戳（15位数字一般是时间戳，小写字母十六进制的一串一般是MD5、SHA1加密，大写字母加数字一般是Base64加密）
将Form表单数据粘到sublime正则匹配操作一波
用同样的方式处理一下请求头headers，并提取一下response里的翻译结果
最后代码如下,其中的form_dict要转下码 urlopen传参也要传data参数，这样才是post请求
