輸入要翻譯的內容時 ， 地址並未發生變化，因此可斷定是向介面傳送的ajax請求

並且可以看到傳送的是post請求，請求表單資料和響應資料都可以找到，複製form表單資料，然後換一個詞翻譯，同樣複製form表單資料，比較兩個表單資料有哪些不同，以方便去模仿構造資料

Form Data
source: auto
target: en
sourceText: 大象
qtv: fb7019db18d2efd2
qtk: tMDoh4iZnYF7a6MshJPtOvA7vXOMj0j+MUFcj6Ogl94MkIim6UUYl/KC4sv03GvVBnb2t6BbmOnew9ASvvKDh+sjJh7tOjLhy1W1M/S/xofJ469ZnMym2es4NJ2Ux8q3pZ0r/RCLPOPc15BSupGOcQ==

sessionUuid: translate_uuid1542022664896
 

可以看到 表單不同處只是輸入的關鍵詞和sessionUuid，看uuid後面的數字不知道是啥，有點像時間戳，去站長之家的工具箱搜了一下確實是毫秒制的時間戳（15位數字一般是時間戳，小寫字母十六進位制的一串一般是MD5、SHA1加密，大寫字母加數字一般是Base64加密）

將Form表單資料粘到sublime正則匹配操作一波

用同樣的方式處理一下請求頭headers，並提取一下response裡的翻譯結果

最後程式碼如下,其中的form_dict要轉下碼   urlopen傳參也要傳data引數，這樣才是post請求
