node.js - express 无法接受到jQuery ajax 过来的formdata数据

问题描述

ajax部分

$.ajax({ url: ’/article/create’, type: ’POST’, data: formData,//<----要传输的数据 async: false, cache: false, timeout:100, contentType: false,//<----头信息设置为false processData: false, success: function(data){ alert('文件上传成功'); }, error: function(xhr){ alert(’文件上传失败：原因是’ + xhr.status); } });//end ajax

express代码

var multer = require(’multer’)var storage = multer.diskStorage({ destination: function (req, file, cb){cb(null, ’./public/upload’) }, filename: function (req, file, cb){cb(null, file.originalname) }});var uploadsingle = multer({ storage: storage});exports.savePost = function (req,res,next) { // console.log(req.files); 打印出来是undefined var upload=uploadsingle.single(’file’); upload(req, res, function (err) { // console.log(req); console.log(’ok’); console.log(err); next() })

问题解答

npm install --save multer
