4.6 从minio上下载文件

示例是从mio上下载pdf结尾的文件

mio操作api：https://docs.min.io/docs/javascript-client-api-reference.html#fGetObject

src/config.js

module.exports = {
    endPoint: '192.168.1.3', //这里不能带http或者https
    port: 9000,
    useSSL: false, //不需要https
    accessKey: 'G2ga7dnJxg7M24C8',
    secretKey: 'ch7by1y17ytbXZOowW9PMz2lF69mzElX'
}

src/run.js

使用promise解决异步

const config = require('./config')
const Minio = require('minio')

let connect = async (config,client) => {
    return new Promise((resolve, reject) => {
        let bucket_name = null
        client.listBuckets(function (err, buckets) {
            if (err) return console.log(err)
            for (let i in buckets) {
                if
