VUE对接阿里云视频点播客户端JavaScript上传SDK

我之前用的是服务端java上传，不过后来因为换了key（accessKeyId，accessKeySecret）值后发现上传变得很慢，有时候会快一点，不过也不是太影响流程，但是不管快慢都会出现无法立即获取到上传后的播放地址，然后我进断点看了一下是可以的，发现是因为断点往下进行的慢，如果进断点后直接走完结束掉也是无法立即获取的，最后也没有解决掉，所以换成前端上传了

好该上班了，直接代码走一下（代码都是官方demo的）

一、第一步根据官方文档引入js文件

这一块要说明一下 VUE2.0与3.0引入可能会有区别，那就可以按照我的方式来引入

引入根据自己的实际开发：

二、引入官方DEMO中的js代码，官方给了两种方式，我用的是推荐的上传地址和凭证方式

1.上传地址和凭证方式(推荐使用)

2.STS方式

我先把整体代码搬出来，我用的前端UI组件是 Ant Design of Vue
