我們可以定義custom formatter並將其傳遞給BeautifulSoup.prettify方法(在你的情況有可能有unicode逃避問題,有這麼從here lution):

import requests 

from bs4 import BeautifulSoup 

r = requests.get('https://m.facebook.com/pages_reaction_units/more/?page_id=126721934083985&cursor={%22timeline_cursor%22:%22page_photos%22,%22timeline_section_cursor%22:null,%22has_next_page%22:true}&surface=mobile_page_home&unit_count=3') 


def formatter(string): 
    formatted = bytes(string, 'ascii').decode('unicode-escape') 
    # for Python 2 
    # formatted = string.decode('unicode-escape') 
    return formatted 


res = r.content.decode() 
soup = BeautifulSoup(res, 'lxml') 
print(soup.prettify(formatter=formatter))
