倡萌最近在为客户定制网站时,需要获取优酷视频缩略图,百度了一大圈,所得的方法无非都是:
- VideoUrlParser.class.php 这个类
- 沐风 Youku Videos 1.2.0 插件
- 其他代码版本……
查看了里面的代码,无非都是通过旧版本的优酷api获取数据:
http://v.youku.com/player/getPlayList/VideoIDS/XMjIwNDg2NjU2/timezone/+08/version/5/source/out?password=&ran=2513&n=3
很不幸的是,优酷已经升级这个API,无法再获取视频缩略图,你可以点击上面的链接地址,就可以得到如下如所示的内容:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |

从内容中再也找不到缩略图了。
没办法,倡萌只有去优酷官方查看新的API,新的 API 方式在:http://open.youku.com/docs?id=46,也就是通过 https://openapi.youku.com/v2/videos/show.json 接口,需要“视频id”和“应用key(client_id)”这两个参数。
所以我们要想办法获的“视频id”和“应用key(client_id)”,就可以使用这个接口获取数据。
所以,我们先注册优酷,创建应用,获得“应用key(client_id)”,具体步骤如下:
- 首先要拥有一个优酷帐号,并申请加入开发平台,点击这里注册优酷帐号
- 一个开发者帐号可以申请多个应用(client_id),点击这里申请
- 应用自动生效,可作为开发和测试使用。应用分为四个等级,普通、中级、高级和合作级。升级后不同等级应用可调用不同API。
- API访问频率限制:普通——每小时1000次,中级——每小时5万次,高级——每小时20万次,合作——无限制
有了 client_id,获取到的信息如下:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
{"id":"XMjIwNDg2NjU2", "title":"\u675c\u96ef\u5a9e - \u96ea \u6211\u53ebMT\u63d2\u66f2", "link":"http:\/\/v.youku.com\/v_show\/id_XMjIwNDg2NjU2.html", "thumbnail":"http:\/\/r1.ykimg.com\/054204085264610F6A0A3F40A0CC261A", "bigThumbnail":"http:\/\/r1.ykimg.com\/054104085264610F6A0A3F40A0CC261A", "duration":"226.35", "category":"\u52a8\u6f2b", "state":"normal", "created":"2010-11-06 19:53:54", "published":"2010-11-06 19:58:21", "description":"\u675c\u96ef\u5a9e - \u96ea \u6211\u53ebMT\u63d2\u66f2", "player":"http:\/\/player.youku.com\/player.php\/sid\/XMjIwNDg2NjU2\/partnerid\/490ad1e99b548935\/v.swf", "public_type":"all", "copyright_type":"original", "user":{"id":"3805457","name":"\u9b3c\u0416\u6ce3","link":"http:\/\/v.youku.com\/user_show\/id_UMTUyMjE4Mjg=html"},"tags":"\u6211\u53ebMT\u63d2\u66f2,\u675c\u96ef\u5a9e,\u6211\u53ebMT","view_count":64838,"favorite_count":"230","comment_count":"55","up_count":"896","down_count":"17","operation_limit":[],"streamtypes":["flvhd","flv","hd","3gp","3gphd"],"source":{"id":"1","name":"\u4f18\u9177\u7ad9\u5185WEB\u4e0a\u4f20","link":"http:\/\/www.youku.com\/v_up\/"}} |
第4、5行 就是缩略图,前者小,后者大:
1 2 |
"thumbnail":"http:\/\/r1.ykimg.com\/054204085264610F6A0A3F40A0CC261A", "bigThumbnail":"http:\/\/r1.ykimg.com\/054104085264610F6A0A3F40A0CC261A", |
下面分享下具体的代码样例,懂代码的看下注释应该就明白了:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 |

注:请务必在 30 行填入你申请到的 应用key(client_id)”,否则无法正常使用!!
在实际使用中,我们可以使用
1 |
<?php echo get_youku_video_thumb(); ?> |
输出视频缩略图的网址。
