VUE對接阿里雲視頻點播客戶端JavaScript上傳SDK

我之前用的是服務端java上傳，不過后來因為換了key（accessKeyId，accessKeySecret）值后發現上傳變得很慢，有時候會快一點，不過也不是太影響流程，但是不管快慢都會出現無法立即獲取到上傳后的播放地址，然后我進斷點看了一下是可以的，發現是因為斷點往下進行的慢，如果進斷點后直接走完結束掉也是無法立即獲取的，最后也沒有解決掉，所以換成前端上傳了

好該上班了，直接代碼走一下（代碼都是官方demo的）

一、第一步 根據官方文檔 引入js文件

 

 這一塊要說明一下 VUE2.0與3.0引入可能會有區別，那就可以按照我的方式來引入

 

 引入根據自己的實際開發：

 

二、引入官方DEMO中的js代碼 ，官方給了兩種方式，我用的是推薦的上傳地址和憑證方式

1.上傳地址和憑證方式(推薦使用)

2.STS方式

我先把整體代碼搬出來 ，我用的前端UI組件是 Ant Design of Vue

我自己的代碼

 

 根據自己的組件進行修改，我沒有用官方DEMO上的分片大小、上傳分片數等數據，用的都是默認的沒有寫活，可根據情況來定

接下來是我對方法的理解

fileChange 是選擇文件調用的方法

 

 開始上傳的方法

 

 接下來就是createUploader下面的onUploadstarted開始上傳的方法

 

 這個方法就是根據上面的判斷，uploadInfo.videoId 是否有值，來決定具體執行哪個方法

如果 uploadInfo.videoId 存在, 調用 刷新視頻上傳憑證接口(https://help.aliyun.com/document_detail/55408.html)

這個刷新視頻也是有DEMO的  https://help.aliyun.com/document_detail/61063.html?spm=a2c4g.11186623.6.909.38ed3815y2BIhl

 

 如果 uploadInfo.videoId 不存在,調用 獲取視頻上傳地址和憑證接口(https://help.aliyun.com/document_detail/55407.html)

 

 這兩個就是上圖需要替換的接口地址，需要你后台來進行編輯后，給前端接口地址

接口返回的也就是上圖和代碼所對應的

 

 至此也就差不多結束了，可能有點亂，多多包涵
