提取視頻ID

在播放頁源碼中，可以找到如下視頻信息：

var VIDEO_INFO = {

title: "咱們相愛吧 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即為視頻ID.

請求getinfo接口

使用Chrome瀏覽器的開發者工具監控網絡請求，發現getinfo接口的請求地址如下：

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

我們嘗試構造各個請求參數，然后看看請求結果是什么樣子的。

params = {

'isHLS': False,

'charge': 0,

'vid': 'y00221a60w7',

'defn': 'shd',

'defnpayver': 1,

'platform': 10901,

'sdtfrom': 'v1010',

'host': 'v.qq.com',

'fhdswitch': 0,

'show1080p': 1,

}

參數中的defn為清晰度標識，可選值有sd(標清)、hd(高清)、shd(超清)、fhd(1080P)。請求結果如下：

我們感興趣的有三個列表：fi列表、ci列表、ui列表。

ui列表中的url是視頻真實地址的前綴，選擇ui列表第一個元素中的url即可。

fi列表列出了各個視頻碼流，每一項中的id是碼流的編號，這個參數在后面會用到。

ci列表列出了各個分段的相關信息，各個分段信息中的keyid在后面會用到。

請求getkey接口

同樣，在網絡請求監測中發現getkey接口的請求是這樣的：

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

構造參數如下：

params = {

'otype': 'json',

'vid': 'y00221a60w7',

'format': 10401,

'filename': 'y00221a60w7.p401.4.mp4',

'platform': 10901,

'vt': 217,

'charge': 0,

}

參數中的vid為視頻ID，format為碼流的編號，filename根據分段信息中的keyid得來。以第四個分段為例，說說如何構造filename參數。第四個分段信息中的keyid為y00221a60w7.10401.4，我們將keyid中間的.10替換為.p，然后在末尾加上.mp4即可。

getkey接口的請求結果示例如下：

{

"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粗來了。

構造視頻真實地址

通過網絡監測發現視頻真實地址是像這樣的：

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

分析該地址的構造，不難發現，地址前綴在前面的ui列表中已經得到了，filename也計算出來了，vkey參數就是上面得到的key.

Python代碼示例

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']:

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

運行輸出如下：
