【Python爬虫实例学习篇】——4、超详细爬取bilibili视频

由于经常在B站上学习,但无奈于家里网络太差,在线观看卡顿严重,于是萌生了下载视频的想法(如果只是单纯想下载视频,请用you-get库)。废话不多说直接开干。
(我发现好像很多人在爬bilibili视频的时候都有用到某个API然后还需要一个cid参数,这些在本文中没有用到。。。。)(另外再说明一下,第3篇文章没有通过审核,要看的话去公众号哈哈)
个人博客地址:https://www.asyu17.cn
使用工具

  1. python3.6
  2. requests库
  3. lxml库(xpath解析)
  4. json库(解析json数据获取下载链接)
  5. ffmpeg(合并视频和音频)

目录

  1. 确定视频资源地址
  2. 下载测试
  3. 下载视频和音频(两种方法)
  4. 合并视频和音频
  5. BiliBiliVideo.py
  6. 运行结果

1、确定视频资源地址

(1) 用Chrome随便打开一个视频,Ctrl+Shift+C选择视频框尝试获取视频的链接。结果发现获取的链接地址为:blob:https://www.bilibili.com/198785ae-c0e6-48c1-b27b-36c5af8935c6 ,这是一个blob加密的链接,不能直接访问。

(2) 网上查找资料后,这篇文章给了我灵感,思路:对网页抓包,抓取到视频分片的链接,再利用所抓到的链接信息进行定位。
【Python爬虫实例学习篇】——4、超详细爬取bilibili视频_第2张图片
(3) 可以定位到所有视频分片的信息全部来源于 https://www.bilibili.com/video/av56643958
【Python爬虫实例学习篇】——4、超详细爬取bilibili视频_第3张图片
(4) 对这部分json代码进行解析(完整json数据太大,请自行去 B站 找到对应位置观看),可以发现:
        quality参数是指视频清晰度,112为高清1080p+、80为高清1080p、64为高清、32为清晰、16为流畅。
        duration参数是指视频长度,单位为秒。
        frameRate参数为帧率。
        SegmentBase参数应该是视频片初始片大小和片基址范围,单位为字节。
        deadline参数是在url里的参数,指示了链接失效的时间戳。

2、下载测试

(1) 既然确定了上述链接就是我们要请求的视频链接,那么尝试直接发送获取请求看看。
      结果。。。。403错误,服务器拒绝访问。
【Python爬虫实例学习篇】——4、超详细爬取bilibili视频_第4张图片
(2) 继续回到Fiddler检查抓包数据发现,同一链接反复出现。仔细观察返回码发现:返回码为200时无数据、请求方式为OPTIONS,返回码为206时有数据、请求方式为GET。查阅资料后猜测,在获取b站视频之前需要用OPTION方式向请求服务器分配资源,然后再用GET方式获取视频分片。
【Python爬虫实例学习篇】——4、超详细爬取bilibili视频_第5张图片
(3) 下面进行获取一个视频分片的测试,考虑到不管是这个OPTIONS请求还是GET请求,其connect属性皆是kepp-alive,考虑使用requests.session()来保持会话。

发现是能够成功下载视频的,但是该视频不能打开。

(4) 重新设置Range的范围为’Range’: ‘bytes=0-4639000’ 后,视频大小为4.42MB,能够正常观看时长为59秒(视频无声音)。猜测:之前下载的908字节不足以构成一个(该视频分辨率为960*534,故猜测应该是62.57kb构成一个画面),另外视频无声音,查找资料后得知,B站的视频和音频是分离的(此时联想到json解析最后一组数据没有分辨率,猜测可能是音频的链接)。
【Python爬虫实例学习篇】——4、超详细爬取bilibili视频_第7张图片
验证成功,最后一个链接为音频的链接
【Python爬虫实例学习篇】——4、超详细爬取bilibili视频_第8张图片

3、下载视频和音频(两种方法)

方法1:取消range参数直接一次下载整个视频或音频
【Python爬虫实例学习篇】——4、超详细爬取bilibili视频_第9张图片
方法2:利用416报错码进行分片下载,每次下载1MB的资源,最后一次将range设置为,‘Range’: ‘bytes=上一次末尾-’。从而实现分片下载。

    # 获取视频链接和音频链接
    VideoURL = videojson['data']['dash']['video'][0]['baseUrl']
    AudioURl = videojson['data']['dash']['audio'][0]['baseUrl']
    print(videojson)
    #获取视频资源的名称
    name = str(html.xpath("//h1/@title")[0].encode('ISO-8859-1').decode('utf-8'))
    # 下载视频和音频
    BiliBiliDownload(url=VideoURL, name=name + '_Video', session=session)

    while True:

        res = session.get(url=url, headers=headers,verify=False)
        if res.status_code != 416:
            begin = end + 1

        with open(name + '.mp4', 'ab') as fp:
            fp.write(res.content)
            fp.flush()

4、合并视频和音频

合并视频和音频我查阅了很多资料,最终决定使用ffmpeg来完成这一操作。z在用合并之前,需要先去安装ffmpeg,详情请参考这篇文章 ffmpeg安装。若是运行过程中出现ffmpeg+一堆乱码,可以参考这篇文章。
下面是合并音频代码:

  1. 需要先在ffmpeg库的video方法中添加如下代码:
# 组合音频和视频 (自己加的)

def combine_audio(video_file, audiio_file, out_file):
    try:
        cmd ='D:/python/ffmpeg-20200115-0dc0837-win64-static/bin/ffmpeg -i '+video_file+' -i '+audiio_file+' -acodec copy '+out_file
        print(cmd)
        subprocess.call(cmd, shell=True)  # "Muxing Done
        print('Muxing Done')
        if res != 0:
            return False
        return True
    except Exception:
        return False
  1. 随后在自己的BiliBiliVideo.py中调用如下代码即可
# 一下path都需要使用全路径
def CombineVideoAudio(videopath,audiopath,outpath):
    ffmpeg.video.combine_audio(videopath,audiopath,outpath)

5、BiliBiliVideo.py

以下是完整代码:

import requests
import json
from lxml import etree
import ffmpeg.video
import os

requests.packages.urllib3.disable_warnings()

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3970.5 Safari/537.36',
    'Referer': 'https://www.bilibili.com/'
}


def GetBiliVideo(homeurl,num,session=requests.session()):
    res = session.get(url=homeurl, headers=headers, verify=False)
    html = etree.HTML(res.content)
    videoinforms = str(html.xpath('//head/script[3]/text()')[0])[20:]
    videojson = json.loads(videoinforms)
    # 获取详情信息列表
    #listinform = str(html.xpath('//head/script[4]/text()')[0])
    listinform = str(html.xpath('//head/script[4]/text()')[0].encode('ISO-8859-1').decode('utf-8'))[25:-122]
    listjson=json.loads(listinform)
    # 获取视频链接和音频链接
    try:
        # 2018年以后的b站视频,音频和视频分离
        VideoURL = videojson['data']['dash']['video'][0]['baseUrl']
        AudioURl = videojson['data']['dash']['audio'][0]['baseUrl']
        flag=0
    except Exception:
        # 2018年以前的b站视频,格式为flv
        VideoURL = videojson['data']['durl'][0]['url']
        flag=1
    # 获取文件夹的名称
    dirname = str(html.xpath("//h1/@title")[0].encode('ISO-8859-1').decode('utf-8'))
    if not os.path.exists(dirname):
        # 如果不存在则创建目录
        # 创建目录操作函数
        os.makedirs(dirname)
        print('目录文件创建成功!')
    # 获取每一集的名称
    name=listjson['videoData']['pages'][num]['part']
    print(name)
    # 下载视频和音频
    print('正在下载 "'+name+'" 的视频····')
    BiliBiliDownload(homeurl=homeurl,url=VideoURL, name=os.getcwd()+'/'+dirname+'/'+name + '_Video.mp4', session=session)
    if flag==0:

        BiliBiliDownload(homeurl=homeurl,url=AudioURl, name=os.getcwd()+'/'+dirname+'/'+name+ '_Audio.mp3', session=session)
        print('正在组合 "'+name+'" 的视频和音频····')
    # CombineVideoAudio(name + '_Video.mp4',name + '_Audio.mp3',name + '_output.mp4')
    print(' "'+name+'" 下载完成!')

def BiliBiliDownload(homeurl,url, name, session=requests.session()):
    headers.update({'Referer': homeurl})
    session.options(url=url, headers=headers,verify=False)
    # 每次下载1M的数据
    begin = 0
    end = 1024*512-1
    flag=0
    while True:
        headers.update({'Range': 'bytes='+str(begin) + '-' + str(end)})
        res = session.get(url=url, headers=headers,verify=False)
        if res.status_code != 416:
            begin = end + 1
            end = end + 1024*512
        else:
            headers.update({'Range': str(end + 1) + '-'})
            res = session.get(url=url, headers=headers,verify=False)
            flag=1
        with open(name, 'ab') as fp:
            fp.write(res.content)
            fp.flush()

        # data=data+res.content
        if flag==1:
            fp.close()
            break

def CombineVideoAudio(videopath,audiopath,outpath):
    ffmpeg.video.combine_audio(videopath,audiopath,outpath)
    os.remove(videopath)
    os.remove(audiopath)



if __name__ == '__main__':

    # av44518113
    av = input('请输入视频号:')
    url='https://www.bilibili.com/video/'+av
    # 视频选集
    range_start=input('从第几集开始?')
    range_end = input('到第几集结束?')
    if int(range_start)<=int(range_end):
        for i in range(int(range_start),int(range_end)+1):
            GetBiliVideo(url+'?p='+str(i),i-1)

    else:
        print('选集不合法!')
