打开链接会发现很正常啊，但是你打开元素审查工具，就会发现框框，是字体反爬，我们就把猫眼的字体反爬解决下

# !/usr/bin python3                                 
# encoding    : utf-8 -*-

import requests
import re

from fontTools.ttLib import TTFont

url = 'https://maoyan.com/board/1'
headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.114 Safari/537.36"
}

response = requests.get(url=url,headers=headers).text

找加密字体的文件：

我们用正则把它提取出来，不能写死字体连接，加个https:+url,保存下来

font_link = re.findall(r"//.*?.woff",response)[0]
p_link = 'https:'+font_link
font_data = requests.get(url=p_link,headers=headers).content
with open('1.woff','wb') as f:
    f.write(font_data)

我们还是用TTFont解析字体，保存成我们更容易看的xml文件，并且构建映射关系

font = TTFont("1.woff")
font.saveXML('1.xml')
new_font_dict = {}
font_map = font['cmap'].getBestCmap()

我们看xml的cmap部分，写出映射

font_dict = {"x":".","uniE137":8,"uniE343":1,"uniE5E2":4,"uniE7A1":9,"uniE8CD":5,"uniF19B":2,"uniF489":0,"uniF4EF":6,"uniF848":3,"uniF88A":7}

我这里用了最笨的方法，因为我没循环字典都被覆盖了，我也不知道怎么情况

num_list = []
key_list = []
for k,v in font_dict.items():
    num_list.append(v)
for d,b in font_map.items():
    t = str(hex(int(d))).replace('0x','&#x')+';'
    key_list.append(t)
new_dict = dict(zip(key_list,num_list))

定义两个空列表一个为key,一个为value，调用zip自动生成一个字典，将我们的key替换成拼接，到代码里把它替换成想对应的值

for i,r in new_dict.items():
    response = response.replace(str(i),str(r))

整体代码

# encoding    : utf-8 -*-
