如果需要加密，需要在aliyun开启密钥服务，然后把密钥id写入代码，当如aliyun提供了密钥别名，所以最好用别名

前端

<div class="prism-player" id="J_prismPlayer"></div> <script> var player = new Aliplayer({ id: "J_prismPlayer", width:"1000px", height:"640px", format: 'm3u8',useFlashPrism: true,vid:"<%= @play_auth[:VideoId] %>", playauth:"<%= @play_auth[:PlayAuth] %>", cover:"<%= @play_auth[:CoverURL] %>" });</script>

当然，也需要引入js，因为就一个页面用，就直接在前端引用了
