腾讯视频的地址解析下载

来源：www.45fan.com 2019-03-29 17:39:32

以腾讯视频播放页地址http://v.qq.com/x/cover/rz4mhb6494f12co.html为例，说说如何解析得到视频的真实地址。

提取视频ID

在播放页源码中，可以找到如下视频信息：

var VIDEO_INFO = {
  title: "咱们相爱吧 第1集",
  duration: "2746",
  vid: "y00221a60w7",
  piantou:"0",
  pianwei:"0",
  showMark:"1",
  showBullet:true,
  showImageBullet:false,
  openBulletDefault:true,
  isNeedPay: false,
  isTrailer: 0,
  singlePrice: "undefined",
  vipPrice: "undefined",
  tryTime: "1306029",
  isTrailer : 0,
  type: "2"
};

其中，vid的值y00221a60w7即为视频ID.

请求getinfo接口

使用Chrome浏览器的开发者工具监控网络请求，发现getinfo接口的请求地址如下：

http://h5vv.video.qq.com/getinfo?callback=txplayerJsonpCallBack_getinfo_591513&isHLS=false&charge=0&vid=y00221a60w7&defn=hd&defnpayver=1&otype=json&guid=29a06bf3852fbe2ea6eb53829c3878fa&platform=10901&sdtfrom=v1010&host=v.qq.com&_rnd=1479010822&fhdswitch=0&show1080p=1&_qv_rmt=sNk0sWZTA17002uQa%3D&_qv_rmt2=0Qs65I9%2B149182HOQ%3D&_=1479010820769

我们尝试构造各个请求参数，然后看看请求结果是什么样子的。

params = {
  'isHLS': False,
  'charge': 0,
  'vid': 'y00221a60w7',
  'defn': 'shd',
  'defnpayver': 1,
  'otype': 'json',
  'platform': 10901,
  'sdtfrom': 'v1010',
  'host': 'v.qq.com',
  'fhdswitch': 0,
  'show1080p': 1,
}

参数中的defn为清晰度标识，可选值有sd（标清）、hd（高清）、shd（超清）、fhd（1080P）。请求结果如下：

   }
  ]
 }
}

我们感兴趣的有三个列表：fi列表、ci列表、ui列表。

ui列表中的url是视频真实地址的前缀，选择ui列表第一个元素中的url即可。
fi列表列出了各个视频码流，每一项中的id是码流的编号，这个参数在后面会用到。
ci列表列出了各个分段的相关信息，各个分段信息中的keyid在后面会用到。

请求getkey接口

同样，在网络请求监测中发现getkey接口的请求是这样的：

http://h5vv.video.qq.com/getkey?callback=txplayerJsonpCallBack_getkey_931033&&otype=json&vid=y00221a60w7&format=10401&filename=y00221a60w7.p401.4.mp4&platform=10901&vt=203&charge=0&_rnd=1479015483148&_=1479015476641

构造参数如下：

params = {
  'otype': 'json',
  'vid': 'y00221a60w7',
  'format': 10401,
  'filename': 'y00221a60w7.p401.4.mp4',
  'platform': 10901,
  'vt': 217,
  'charge': 0,
}

参数中的vid为视频ID，format为码流的编号，filename根据分段信息中的keyid得来。以第四个分段为例，说说如何构造filename参数。第四个分段信息中的keyid为y00221a60w7.10401.4，我们将keyid中间的.10替换为.p，然后在末尾加上.mp4即可。

getkey接口的请求结果示例如下：

{
 "br": 125315.14,
 "ct": 21600,
 "filename": "y00221a60w7.p401.mp4",
 "key": "AE6DC4B022C2A29C59D1A8E942787A2A54F64A5ABFCA7C99B51BD6539703D4F745DD2D77C3433ACAF1961BBFB6D84C1C717D23BEDCAF4DABC0D8BA2229F6C3464F59F0A10C5ED4CC25E355D9171DC65D411D6834BCA2DECD",
 "keyid": "y00221a60w7.10401.4",
 "level": 0,
 "levelvalid": 1,
 "s": "o",
 "sp": 0,
 "sr": 0
}

看！key粗来了。

构造视频真实地址

通过网络监测发现视频真实地址是像这样的：

http://60.206.195.15/vlive.qqvideo.tc.qq.com/y00221a60w7.p401.4.mp4?sdtfrom=v1010&guid=29a06bf3852fbe2ea6eb53829c3878fa&vkey=6C5D63159598E6D217BA73F6F3335C0B80CECE2A4E889AFCDD8A391DB9C648059731AE9AD47BDA03B016F76E8B59D9DF0C2373CA32A4ADB935AEE0FE73ECE1C460DC01F6B733A5F38035AC289C44721F606C1ADF5AED4267

分析该地址的构造，不难发现，地址前缀在前面的ui列表中已经得到了，filename也计算出来了，vkey参数就是上面得到的key.

Python代码示例

import requests
import json

vid = 'y00221a60w7' # replace with your vid
for definition in ('shd', 'hd', 'sd'):
  params = {
    'isHLS': False,
    'charge': 0,
    'vid': vid,
    'defn': definition,
    'defnpayver': 1,
    'otype': 'json',
    'platform': 10901,
    'sdtfrom': 'v1010',
    'host': 'v.qq.com',
    'fhdswitch': 0,
    'show1080p': 1,
  }
  r = requests.get('http://h5vv.video.qq.com/getinfo', params=params)
  data = json.loads(r.content[len('QZOutputJson='):-1])

  url_prefix = data['vl']['vi'][0]['ul']['ui'][0]['url']
  for stream in data['fl']['fi']:
    if stream['name'] != definition:
      continue
    stream_id = stream['id']
    urls = []
    for d in data['vl']['vi'][0]['cl']['ci']:
      keyid = d['keyid']
      filename = keyid.replace('.10', '.p', 1) + '.mp4'
      params = {
        'otype': 'json',
        'vid': vid,
        'format': stream_id,
        'filename': filename,
        'platform': 10901,
        'vt': 217,
        'charge': 0,
      }
      r = requests.get('http://h5vv.video.qq.com/getkey', params=params)
      data = json.loads(r.content[len('QZOutputJson='):-1])
      url = '%s/%s?sdtfrom=v1010&vkey=%s' % (url_prefix, filename, data['key'])
      urls.append(url)

    print 'stream:', stream['name']
    for url in urls:
      print url

运行输出如下：

stream: shd
