VUE如何实现element upload上传图片到阿里云的案例(element,upload,vue,开发技术)

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 })}
