正则匹配酷6视频url后使用接口引用案例

通过酷6的一个转发接口，使用java正则来获取匹配酷6网大部分视频网址链接，抓取获得ip、flash、title等属性用于内嵌视频展示;关键代码是抓取数据，展示代码很简单。大致效果图如下：

1.抓取数据代码：

2.展示代码：

展示其实很简单，动态的拼装一个embed标签放到html或jsp页面就行；格式如下：

<embedsrc="http://player.ku6.com/refer/flKjsasaK0W9fdCsFYO99A../v.swf"width="480" height="400"allowscriptaccess="always" allowfullscreen="true"type="application/x-shockwave-flash" ></embed>

在action中动态拼装的参数为src，src就是上面抓取程序抓到的参数了，还有一些抓到的title和description用于内嵌页面的其他样式展示用。

关于embed标签的使用方式可参考：http://www.52php.cn/article/p-gakwyywu-da.html
