首先安装依赖
cnpm install ali-oss
封装client
若是想减小打包后静态资源大小,可在index.html引入:(然后在client.js里注释掉const oss = require(‘ali-oss'))
<script src="http://gosspublic.alicdn.com/aliyun-oss-sdk-4.4.4.min.js"></script>

const oss = require( 'ali-oss' ) export function client(data) { // 后端提供数据 return new oss({ region: data.endpoint, // *****.aliyuncs.com accesskeyid: data.accesskeyid, accesskeysecret: data.accesskeysecret, bucket: data.bucketname, endpoint: data.endpoint, secure: true }) } |
然后,在vue页面引用,给client传入后台返回的阿里数据
结果如下图:

补充知识:vue-cli项目中,配合element_ui来实现上传图片与视频到oss上。
