Python爬蟲：抖音 JS XB逆向解析

哈嘍兄弟們，抖音現在有JS加密，以前的方法爬不了餓了，今天來實現一下某音短視頻的JS逆向解析。

知識點

動態數據抓包`在這裡插入代碼片`
requests發送請求
X-Bogus 參數逆向

環境模塊

python 3.8               運行代碼
pycharm 2022.3           輔助敲代碼
requests                 pip install requests 安裝

源碼

獲取數據部分

import requests
import execjs
 
 
ctx = execjs.compile(open('xb.js', mode='r', encoding='utf-8').read())
headers = {
    'referer': 'https://www.douyin.com/user/MS4wLjABAAAAqsOmrExIsJbZ2b0QLzytzAhAFbJUROH72_yVYM7Zq8E?vid=7273024102460362047',

url = 'https://www.douyin.com/aweme/v1/web/aweme/post/?'
xb = arg1 + '&X-Bogus=' + ctx.call('window.siyue111', arg1)
url += xb
print(url)
response = requests.get(url, headers=headers)
json_data = response.json()
aweme_list = json_data['aweme_list']
for aweme in aweme_list:
    desc = aweme['desc']
    video_url = aweme['video']['play_addr']['url_list'][0]
    # JS解密部分太長了，我直接打包了，還錄製了詳細講解的視頻。
    # 都放在這個扣裙了 592539176
    print(desc, video_url)

JS解密部分太長了，我直接打包了，還錄製了詳細講解的視頻。

好了，今天的分享就到這裡結束了，下次見！
