一五六、Node+Vue 使用七牛上传图片，并配置个人域名

1. 七牛云ak/sk获取

点击注册🔗开通七牛开发者帐号
如果已有账号，直接登录七牛开发者后台，点击这里🔗查看 Access Key 和 Secret Key

2. Node.js获取七牛token

安装qiniu

npm install qiniu

创建空间
在这里插入图片描述

Node获取token

const qiniu = require('qiniu');
const ACCESS_KEY = 'xxx';
const SECRET_KEY = 'xxx';
const mac = new qiniu.auth.digest.Mac(ACCESS_KEY, SECRET_KEY);

const {Auth} = require('@middlewares/auth');
const AUTH_ADMIN = 16;

const {Resolve} = require('@lib/helper');
const res = new Resolve();

const Router = require('koa-router');

const router = new Router({
    prefix: '/api/v1'
});

// 获取token
router.post('/upload/token', new Auth(AUTH_ADMIN).m, async ctx => {
    const options = {
        scope: 'xxx', //你的存储空间名称
        expires: 7200
    };
    const putPolicy = new qiniu.rs.PutPolicy(options);
    ctx.response.status = 200;
    const data = {
        token: putPolicy.uploadToken(mac)
    };
    ctx.body = res.json(data);
});

module.exports = router;

3. Vue获取token并上传图片

获取token

//src/api/upload.js
import request from '@/utils/request';

// 获取上传图片token
export function getToken(params) {
    return request({
        url: '/upload/token',
        method: 'post',
        params
    });
}
