七牛云上传图片element的upload组件

步骤:

1. 后端使用AccessKey,SecretKey,Bucket生成token给前端
2. 前端使用Domain和后端返回的token去调用qiniu的SDK上传文件

解释:

AccessKey,SecretKey:秘钥,在这里可以查看到https://portal.qiniu.com/user/key

Bucket:存储空间,在这里可以查看到https://portal.qiniu.com/kodo/bucket

Domain:存储空间Bucket对应的域名,通过这个域名和一个key值可以访问到图片,https://portal.qiniu.com/kodo/bucket/domain?bucketName=BucketName

 

前端具体使用步骤:官方文档

• 安装和引入插件 3.1版本

安装:
npm install qiniu-js


引入:
const qiniu = require('qiniu-js')
// or
import * as qiniu from 'qiniu-js'

• 上传组件

    
      
    



    data:
    
      fileList: [],
      uploadUrl: "http://qiniu.XXXXXXX.com/",//Domain,上传的域名
      uploadData: {//上传携带的额外参数
        key: "filename", //上传的文件名
        token: "", //后端生成的token
      },
