项目图片 地址源切换

最近项目图片地址源切换，需要把地址从火山迁移到阿里，项目中那么多图片地址，为了省事，公司同事写了一个全局替换的脚本，觉得非常好，记录一下

const fs = require('fs')
const http = require("http");
var request = require('request')
const path = require('path')
var FormData = require('form-data');
const randomString = (e)=>  {
    e = e || 32;
    var t = "ABCDEFGHJKMNPQRSTWXYZabcdefhijkmnprstwxyz2345678",
        a = t.length,
        n = "";
    for (var i = 0; i < e; i++) {
        n += t.charAt(Math.floor(Math.random() * a))
    }
    return n + Date.now()
}

            a(path.join(sourcePath, item))
        })
    } else {

把这个文件放在根目录下面 node 执行一下就可以啦
