NodeJS使用formidable实现文件上传

.post('/add', handler.doAdd)
.get('/edit', handler.showEdit)
.post('/edit', handler.doEdit)
.get('/remove', handler.doRemove)

module.exports = router;

　　注意：router.js文件中的依赖不用多说。

4.创建handler.js文件

const formidable = require('formidable');
const config = require('./config');
const db = require('./common/db');
const path = require('path');
const fs = require('fs');
exports.doAdd = (req, res) => {
  const form = new formidable.IncomingForm();
  form.uploadDir = config.uploadDir;//上传文件的保存路径
  form.keepExtensions = true;//保存扩展名
  form.maxFieldsSize = 20 * 1024 * 1024;//上传文件的最大大小
  form.parse(req, (err, fields, files) => {
    if (err) {
      throw err;
    }
    const title = fields.title;
    const singer = fields.singer;
    const music = path.basename(files.music.path);
    const img = path.basename(files.img.path);
    db.query('INSERT INTO music (title,singer,music,img) VALUES (?,?,?,?)', [
      title,
      singer,
      music,
      img
    ], (err, rows) => {
      if (err) {
        throw err;
      }
      res.redirect('/');
    })
  })
};
