分析网站

先打开开发者工具，然后搜索m3u8，会返回给你很多的ts的文件，像这种ts文件，就是视频的片段

我们可以复制url地址，在新的浏览页打开

然后会给我们下载ts的文件，打开文件，就会发现是十多秒的视频片段

所以说这些数据的数据还是比较好找的，只要我们找到地址是从哪里来的

找到url地址，因为是post请求，所以需要下面的表达参数

开始代码

导入模块

import requests
import re
from tqdm import tqdm # 进度条展示

数据请求

url = 'https://vd.l.qq.com/proxyhttp'
data = {"buid":"vinfoad","adparam":"pf=in&ad_type=ld%7ckb%7cpvl&pf_ex=pc&url=https%3a%2f%2fv.qq.com%2fx%2fcover%2fj3czmhisqin799r.html&refer=https%3a%2f%2fv.qq.com%2fx%2fsearch%2f&ty=web&plugin=1.0.0&v=3.5.57&coverid=j3czmhisqin799r&vid=z002615k57t&pt=&flowid=e9b3e49b2593efd194cbcd24030ed803_10201&vptag=www_baidu_com%7cvideo%3aposter_tle&pu=-1&chid=0&adaptor=2&dtype=1&live=0&resp_type=json&guid=4b4e192e83f4abaf8b68df3e4f5be769&req_type=1&from=0&appversion=1.0.166&uid=522810848&tkn=fbyfewdclktaaod_ogvcng..&lt=qq&platform=10201&opid=5fe180427a4c883f69cadded665ce99b&atkn=49c1a486316c8d269ac65aac080cfb29&appid=101483052&tpid=1&rfid=86c3f668da63d8bc7aab3fbc1eb7378a_1633763084","vinfoparam":"spsrt=1&charge=0&defaultfmt=auto&otype=ojson&guid=4b4e192e83f4abaf8b68df3e4f5be769&flowid=e9b3e49b2593efd194cbcd24030ed803_10201&platform=10201&sdtfrom=v1010&defnpayver=1&appver=3.5.57&host=v.qq.com&ehost=https%3a%2f%2fv.qq.com%2fx%2fcover%2fj3czmhisqin799r.html&refer=v.qq.com&sphttps=1&tm=1633767536&spwm=4&logintoken=%7b%22main_login%22%3a%22qq%22%2c%22openid%22%3a%225fe180427a4c883f69cadded665ce99b%22%2c%22appid%22%3a%22101483052%22%2c%22access_token%22%3a%2249c1a486316c8d269ac65aac080cfb29%22%2c%22vuserid%22%3a%22522810848%22%2c%22vusession%22%3a%22fbyfewdclktaaod_ogvcng..%22%7d&vid=z002615k57t&defn=fhd&fhdswitch=0&show1080p=1&ishls=1&dtype=3&sphls=2&spgzip=1&dlver=2&drm=32&hdcp=0&spau=1&spaudio=15&defsrc=2&encryptver=9.1&ckey=w5agxknj7n56kjeitzs_lpjx5wb4a2cds8keio8rvaqthezq1c_w6myj8hqxnmddg8erejdmljvm2vpbr-xe-uhvzyemy131vuh1h4pgcxe2ophm_h32jqtu2hfoqfa-un0svbkixyfwkodabnbluo4rgzsxkbhf3n3k7dnkpg_56x9jo3gwbmybeaex05x8sbbqky5axadvsm7hsbq8xeehziegjzlct94ongpyvsrkzqo51nvr_bs8h4-unlt0jg-obbyns2ijhrz4jubeugek8zaohe9htzpndvilriyt2mndud09qsllkl4xaj3ce6i26p6bryay1_qatijxkm9j1hs3zyc7dgymazd6be9ugx4hkzity-y8ccbppeebgsaj9w&fp2p=1&spadseg=3"}

headers = {
    'user-agent': 'mozilla/5.0 (windows nt 10.0; win64; x64) applewebkit/537.36 (khtml, like gecko) chrome/94.0.4606.71 safari/537.36'
}
response = requests.post(url=url, json=data, headers=headers)

提取数据

html_data = response.json()['vinfo']
# 正则表达式
m3u8_url = re.findall("url(.*?),", html_data)[3].split('"')[2]
m3u8_data = requests.get(url=m3u8_url).text
m3u8_data = re.sub('#extm3u', '', m3u8_data)
m3u8_data = re.sub('#ext-x-version:\d', '', m3u8_data)
m3u8_data = re.sub('#ext-x-media-sequence:\d', '', m3u8_data)
m3u8_data = re.sub('#ext-x-targetduration:\d+', '', m3u8_data)
m3u8_data = re.sub('#ext-x-playlist-type:vod', '', m3u8_data)
m3u8_data = re.sub('#extinf:\d+\.\d+,', '', m3u8_data)
m3u8_data = re.sub('#ext-x-endlist', '', m3u8_data).split()

遍历

for ts in tqdm(m3u8_data):
    ts_url = 'https://apd-57c5d150c8b9788baf40ea4f65feddf8.v.smtcdns.com/moviets.tc.qq.com/a2k4juw9atia8thdfq6y5hwruglqar4l5fk9kfbauei8/uwmrofz2r5xgoaqxgdgnc2df64gvtkzl5c_x6a3jovt0qib-/dovi4hwq0sqexpo_ylkyxvijdr9zz2vwewbcy7x70krnbvnpvbaotsjwfoq1uojotsrkj8r3372hratovg4vykoffvzjq2eemdpleiiytv0tb-c3czxmkzz-34hk4fc-r4mzk55l9w1rqjmpsvrorzr_sqpqvgzrrrq830get0nljgkeaq9sbg/' + ts
    ts_content = requests.get(url=ts_url).content

保存数据

with open('霸王别姬.mp4', mode='ab') as f:
    f.write(ts_content)
print('下载完成')
