小程序真是一步一坑，最近在做一个视频播放组件，需要一些视频的url地址，结果发现直接拿腾讯视频中url根本不行，在网上看了好多帖子说的也不是特别详细，结果自己用了一天时间研究整理了一下，写了一个获取可用url的方法。希望能帮助到大家

先看效果

我们从腾讯视频网站上找到一个视频网页的连接，具体步骤就是打开视频点击分享，那个分享的链接就是我们要的

两个都可以复制下来  复制下来后是这样子 我们只需要src里的这段：

我们把上面链接的vid放到以下接口地址上 

http://vv.video.qq.com/getinfo?vid=h056607xye8&platform=101001&charge=0&otype=json

直接访问返回的是

 我们把前面的QZOutputJson=跟最后的 ; 过滤掉，得到一个json字符串了。解析它变成json对象，然后把标红的三个部分组合一下，顺序是 

url + fn + '?vkey=' + fvkey 

例如上面这串，组合下来就是

这个地址就可以直接放在小程序的video组件里面播放了。
