【uniapp】视频分享预览小程序
六一收到个不同以往的需求，我的指导老师最近有点忙，让我们帮忙做一个可以通过二维码预览视频的小程序
收到需求后，因为只是临时用一下，不打算写一套完整的系统，所以大概的思路就是，其他成员将视频通过ftp传入我的服务器上，我通过uniapp将视频路径写死在index页面上，跳转时将url中的参数传入到下一个页面即可，视频播放页面通过拼接路径最后得到完整的src资源文件，在写入data完成渲染即可，同理在点击生成二维码时将参数带着去新的页面进行处理，得到该视频播放页面的url后利用qrcode进行渲染输出二维码
basic:[
{"name":"蔡晓东英雄事迹","url":"/pages/video/video?url=1.mp4"},
{"name":"云南传统手工业银器制作","url":"/pages/video/video?url=2.mp4"},
{"name":"高山流水的典故","url":"/pages/video/video?url=3.mp4"}

index页面
点击预览，跳转到视频播放页面
点击qrcode，跳转到二维码生成页面

视频播放页面
资源渲染后即可直接播放，这部分的代码找了好久，起初以为uniapp没有支持网页播放的能力，需要用第三方的。
