使用node.js发送附件数组

npm init -y

npm install express multer

const express = require('express');
const multer = require('multer');
const path = require('path');

const app = express();

// 设置存储引擎和文件保存路径
const storage = multer.diskStorage({
  destination: function (req, file, cb) {
    cb(null, 'uploads/');
  },
  filename: function (req, file, cb) {
    cb(null, file.originalname);
  }
});

// 创建multer实例
const upload = multer({ storage: storage });

app.post('/upload', upload.array('attachments'), (req, res) => {
  // 处理上传的文件
  const files = req.files;
  // 其他逻辑处理...
  res.send('文件上传成功！');
});

app.listen(3000, () => {
  console.log('服务器已启动，监听端口3000');
});
