前言

嗨喽，大家好呀~这里是爱看美女的茜茜呐

又到了学Python时刻~

现在好看的妹子真的太多啦~

如何一次性把这些好看的视频全保存下来捏？

image

开发环境:

版本: python 3.8
编辑器: pycharm 2022.3.2 专业版
requests >>> pip install requests
ffmpeg 音视频合成软件

实现一个案例的流程:

一. 思路分析

案例的分析视频 media .mp4 .mp3 .m4a m3u8视频流

.m4s: 视频/音频格式

数据来源分析: 找到视频内容

network抓包

二. 代码实现(代码实现基本流程)

发送请求使用代码的方式访问网站
获取数据取出网页源代码
解析数据提取视频链接
保存数据

导入模块

import requests
import re       # 正则表达式模块
import json
import pprint
import subprocess
import os

伪装(请求头)

headers = {
    # 用户信息
    "cookie": "buvid3=355AA300-6A61-04E5-A05C-E891D886F69632716infoc; b_nut=1675085932; i-wanna-go-back=-1; _uuid=387EA3810-FBF5-E92C-827E-2510B578C5B9A33232infoc; buvid4=15C69C98-F6A7-EC6A-872F-E69C1840DD6D33724-023013021-1pW1w45e5fZS9RtebDiGZw%3D%3D; nostalgia_conf=-1; CURRENT_FNVAL=4048; rpdid=|(kmJY|k))lY0J'uY~l|)lmY|; SESSDATA=17eb9f1a%2C1690782878%2C6a25c%2A22; bili_jct=4af9076b42f76603dfe4cf018ad2000f; DedeUserID=422789639; DedeUserID__ckMd5=fc4901c78719b545; CURRENT_QUALITY=80; b_ut=5; b_lsid=51ED8F105_1861C3EEC10; theme_style=light; is-2022-channel=1; sid=66dafqju; fingerprint=97ca5a8b555e63aca787c9cd27273c7e; buvid_fp_plain=undefined; buvid_fp=8cc52ae38b592ff26dc2b393eebd890b; PVID=2; innersign=1; bp_video_offset_422789639=758803412994228200",

发送请求

url = 'https://www.***.com/video/BV1qv4y1k7UE/?vd_source=8f216a44bce0dbe14e3447c34c2ab3e2'
response = requests.get(url, headers=headers)

获取数据

html_data = response.text

解析数据

json_str = re.findall('__playinfo__=(.*?)</script>', html_data)[0]
# <h1 .*?>(.*?)</h1>
title = re.findall('<h1 .*?>(.*?)</h1>', html_data)[0]
# Python基础 字典
json_data = json.loads(json_str)
# pprint.pprint(json_data)
audio_url = json_data['data']['dash']['audio'][0]['baseUrl']
print(audio_url)
video_url = json_data['data']['dash']['video'][0]['baseUrl']
print(video_url)

保存数据

audio_data = requests.get(audio_url, headers=headers).content
with open(f'{title}.mp3', mode='wb') as f:
    f.write(audio_data)
video_data = requests.get(video_url, headers=headers).content
with open(f'{title}.mp4', mode='wb') as f:
    f.write(video_data)

ffmpeg = f'ffmpeg -i {title}.mp4 -i {title}.mp3 -acodec copy -vcodec copy {title+"-out.mp4"}'
subprocess.run(ffmpeg)
os.remove(f'{title}.mp4')
os.remove(f'{title}.mp3')
