# script.js 匹配md中所有图片，并返回所有图片
function matchImgs (content) {
  // 正则匹配图片
  const images = [];

  content.replace(reg, function (m) {
    const imgUrl = m.replace(/(aaa)/g, 'imgurl'); // 去掉前缀aaa
    images.push(`http://域名/${imgUrl}`)
  })
  return images;
}

const imgs = matchImgs();
exports.imgs = imgs;

# bagpipe.js 批量下载图片
const fs = require("fs");

图片批量上传

const fs = require("fs");
const path = require('path');
import * as child from 'child_process';

function upload () {
  const templateUrl = path.join(process.cwd(), '/images');
  const dirInfo = fs.readdirSync(templateUrl);
  for (let i = 0; i < dirInfo.length; i++) { // 遍历文件目录
    const item = dirInfo[i];
    const location = path.join(templateUrl, item);
    const index = location.lastIndexOf('/');
    const fileName = location.substring(index + 1); // 文件名
    const imgPath = `${templateUrl}/${fileName}`;
    // TODO 上传到图床，获取图片url
  }

node遍历文件目录

const url = process.cwd();
const dirInfo = fs.readdirSync(url);
for (let i = 0; i < dirInfo.length; i++) {
  console.log(dirInfo[i])
  // TODO 获取文件名、路径等信息
