一、網頁分析

開啟谷歌翻譯連結：https://translate.google.com/

按F12，點選network。在左側輸入"who are you"

可以看到，請求的連結為：

https://translate.google.com/_/TranslateWebserverUi/data/batchexecute?rpcids=MkEWBc&f.sid=-2609060161424095358&bl=boq_translate-webserver_20201203.07_p0&hl=zh-CN&soc-app=1&soc-platform=1&soc-device=1&_reqid=359373&rt=c
 

傳送的資料為：

這裡面的who are you表示，需要翻譯的文字

ja 表示日本的簡稱。

    except Exception as e:

        return False

# 翻譯各個國家語言
for i in ['en', 'zh', 'fr', 'ja', 'de']:
    response = translated_content("who are you", i)
    print(response)

執行輸出：

你是誰
qui êtes vous
あなたは誰
