获取腾讯视频真实地址（涉及清晰度选择） - 好文

前言

*

由于需要在小程序插入腾讯视频，于是在网上找了诸多方法，但基本都只能抓到低清版本的；偶然发现大神能抓到超清版（720p）的,但由于自己的视频并不都含有超清的版本，因而只能退而求其次使用480p的；这对于移动端（包括全屏）的清晰度已经足够了。毕竟也不是专门做视频的小程序。

步骤

主要api

* http://vv.video.qq.com/getinfo <http://vv.video.qq.com/getinfo>
* http://vv.video.qq.com/getkey <http://vv.video.qq.com/getkey>
腾讯视频的vids

* 当你打开一个腾讯视频的时候，比如https://v.qq.com/x/page/ <https://v.qq.com/x/page/>
x0164ytbgov.html，vids=x0164ytbgov。
这个将作为参数让我们去访问api.
访问getinfo

* 当我们得到vids后，我们就可以访问api：

http://vv.video.qq.com/getinfo?vids=x0164ytbgov&platform=101001&charge=0&otype=json&defn=shd

<http://vv.video.qq.com/getinfo?vids=x0164ytbgov&platform=101001&charge=0&otype=json&defn=shd>
（如果需要xml格式，就让参数中otype=xml)
* 获取到 json1： QZOutputJson= { "dltype":1, "exem":0, "fl":{ "cnt":2, "fi":[ {
"id":100701,"name":"msd","lmt":0,"sb":1,"cname":"标清;(270P)","br":28,"profile":2,
"drm":0,"video":1,"audio":1,"fs":16546732,"sl":1}, {"id":2,"name":"mp4","lmt":0,

},"vh":256, "vid":"x0164ytbgov", "videotype":0, "vr":0, "vst":2, "vw":480, "wh":
1.875, "wl":{"wi":[]} } ] } };
拼接低清版本的视频地址

* 到这一步，我们就可以获取低清版本的视频源地址了。
* 我们把获取到字符串去掉QZOutputJson=和最后的分号，变成正式的json realVideoURLRequestPath=
"http://vv.video.qq.com/getinfo?vids=x0164ytbgov&platform=101001&charge=0&otype=json&defn=shd"
videoInfo =requests.get(realVideoURLRequestPath) videoInfo_json =
videoInfo.text[len('QZOutputJson='):-1] tempStr = json.loads(videoInfo_json)
* 这样我们就可以获取到 tempStr['vl']['vi'][0]['ul']['ui'][0]['url'] +tempStr['vl']['vi'
][0]['fn'] +"?vkey=" +tempStr['vl']['vi'][0]['fvkey']
* 即：

http://ugcws.video.gtimg.com/x0164ytbgov.m701.mp4?vkey=1E327E4FE26E8B8222C226B0873DBF94C094934198E382AE2910361C29E5396237CCF814A49976A5A485F2E806CBC4C21602406034413F9896BF0972F7678D8263845FD123BA9B3604419489CD2BF4254EFD5F87D62A6F88FFF2A4E38F57C9898DD1F7C38C1F548C

<http://ugcws.video.gtimg.com/x0164ytbgov.m701.mp4?vkey=1E327E4FE26E8B8222C226B0873DBF94C094934198E382AE2910361C29E5396237CCF814A49976A5A485F2E806CBC4C21602406034413F9896BF0972F7678D8263845FD123BA9B3604419489CD2BF4254EFD5F87D62A6F88FFF2A4E38F57C9898DD1F7C38C1F548C>

拼接高清视频地址

* 因为我们这个视最清晰只有高清，所以json中的fi字段 "fi":[ {"id":100701,"name":"msd","lmt":0,"sb":1,
"cname":"标清;(270P)","br":28,"profile":2,"drm":0,"video":1,"audio":1,"fs":
16546732,"sl":1}, {"id":2,"name":"mp4","lmt":0,"sb":1,"cname":"高清;(480P)","br":
33,"profile":1,"drm":0,"video":1,"audio":1,"fs":34433483,"sl":0} ]
* 如果有超清清的话，一般会多一个id为10701的数组元素，如： { "id":10701, "name":"shd", "lmt":0, "sb":1
, "cname":"超清;(720P)", "br":39, "profile":1, "drm":0, "video":1, "audio":1, "fs
":41560039, "sl":0 }
* 这时，我们就需要用到 http://vv.video.qq.com/getkey <http://vv.video.qq.com/getkey> api
* 首先我们先构造filename=[vids]+.mp4 即 filename=x0164ytbgov.mp4
* 然后访问：
http://vv.video.qq.com/getkey <http://vv.video.qq.com/getkey>?format=2
&otype=json&vt=150&vid=x0164ytbgov&ran=0\%2E9477521511726081\\&charge=0&
filename=x0164ytbgov.mp4&platform=11

* 返回json2 QZOutputJson= { "br":62042.312, "ct":21600, "filename":
"x0164ytbgov.mp4", "ip":"120.36.254.197", "key":
"A76112B8282FBD47AE5408A46CBE73D6C3B087688864DAE1C5076726E901E76673A9884A141F398F08A0EB6E9A2C684DA23F92D9A6D0B2787CB108EF75FCD8D7A631A2D40AF2C020392BEE038A662EF1434BF157CAC87218E87A26B65375D06C"
,"keyid":"x0164ytbgov.2", "level":0, "levelvalid":1, "s":"o", "sp":0, "sr":0 };
*
根据这两个json，我们就构造新的连接：

tempStr[‘vl’][‘vi’][0][‘ul’][‘ui’][0][‘url’]+filename+?vkey=key
(key为json2的key),即：

http://ugcws.video.gtimg.com/x0164ytbgov.mp4?vkey=A76112B8282FBD47AE5408A46CBE73D6C3B087688864DAE1C5076726E901E76673A9884A141F398F08A0EB6E9A2C684DA23F92D9A6D0B2787CB108EF75FCD8D7A631A2D40AF2C020392BEE038A662EF1434BF157CAC87218E87A26B65375D06C

<http://ugcws.video.gtimg.com/x0164ytbgov.mp4?vkey=A76112B8282FBD47AE5408A46CBE73D6C3B087688864DAE1C5076726E901E76673A9884A141F398F08A0EB6E9A2C684DA23F92D9A6D0B2787CB108EF75FCD8D7A631A2D40AF2C020392BEE038A662EF1434BF157CAC87218E87A26B65375D06C>

* 这样，我们就获得了高清的视频地址了
拼接超清视频地址

* 前面说过了额，如果有超清清的话，一般会多一个id为10701的数组元素，如： { "id":10701, "name":"shd", "lmt":0,
"sb":1, "cname":"超清;(720P)", "br":39, "profile":1, "drm":0, "video":1, "audio":1
, "fs":41560039, "sl":0 }
* 这时我们构造的filename=x0164ytbgov.p701.1.mp4
* 此时访问getkey的api就要改为：
http://vv.video.qq.com/getkey <http://vv.video.qq.com/getkey>?format=10701
&otype=json&vt=150&vid=x0164ytbgov&ran=0\%2E9477521511726081\\&charge=0&
filename=x0164ytbgov.p701.1.mp4&platform=11

* 聪明的你可能发现了：format={id}
*
到最后构成真实视频的url:
tempStr[‘vl’][‘vi’][0][‘ul’][‘ui’][0][‘url’]+filename+?vkey=key
(key为json2的key,filename=x0164ytbgov.p701.1.mp4)

*
由于测试用的视频地址无超清源，所以超清这块的测试需要使用的超清视频做测试。提示已测试可行。
