前台： <form method=“post” enctype=“multipart/form-data” action="/upload"> <input type=“file” name=“thumbnail”> <input type=“submit”> </form> app.js代码: var express = require(‘express’); var multer = require(‘multer’); var upload = multer({dest:’./public/uploads’}); var app = express(); app.use(upload); app.post(’/upload’,upload.single(‘avatar’),function(req,res,next){ console.log(req.file); res.send(‘ok’); }); multer版本1.1.0 哪位高手有可用的上传代码欢迎贴出来！，谢谢啦！
@jingsam 谢谢回答，删掉之后报这个错了
Unexpected field

你有上传成功的代码示例吗？@jingsam 你好，还有个问题，①如果用表单提交的方式上传，那<input type=“file” name=“avatar”>这个name如何变成自动获取所上传文件的名字？② upload.single(‘avatar’)，这个后台怎么变成取表单传过来的名字？③除了用表单提交的方式，用http的post请求上传文件怎么写？蟹蟹！
