腾讯云web上传文件文档

https://cloud.tencent.com/document/product/266/9239#.E5.B8.B8.E8.A7.81.E9.97.AE.E9.A2.98

sdk:https://github.com/tencentyun/vod-js-sdk-v6

根据文档下载sdk或参考sdk即可

前端源代码地址 https://github.com/tencentyun/vod-js-sdk-v6/blob/master/docs/index.html

注意，前端获取签名的地址要改成自己后台的签名生成地址

在视频上传成功里面加入自己的逻辑

注意 ：

添加签名其他参数时，其他参数要UrlEncode，  比如加转码时

procedure= HttpUtility.UrlEncode("转码任务流");
