Python3的URL編碼解碼

前言

博主最近在用python3比較強大的Django開發web的時候，發現一些url的編碼問題，在瀏覽器提交請求api時，如果url中包含漢子，就會被自動編碼掉。呈現的結果是 ==> %xx%xx%xx。如果出現3個百分比符號為一個原字元則為utf8編碼，如果2個百分比符號則為gb2312編碼。下面為大家示範編碼和解碼的代碼。 編碼

from urllib.parse import quotetext = quote(text, 'utf-8')

註：text為要進行編碼的字串 解碼

from urllib.parse import unquotetext = unquote(text, 'utf-8')
