我正在使用节点v0.10.26并表达v4.2.0,我对节点很新.在过去三个小时左右的时间里,我一直在我的桌子上打我的脑袋试图获得一个与节点一起使用的文件上传表单.在这一点上,我只是想让req.files不返回undefined.我的观点看起来像这样
<!DOCTYPE html>
<html>
<head>
<title>{{ title }}</title>
<link rel='stylesheet' href='/stylesheets/style.css' />
</head>
<body>
<h1>{{ title }}</h1>
<p>Welcome to {{ title }}</p>
<form method='post' action='upload' enctype="multipart/form-data">
<input type='file' name='fileUploaded'>
<input type='submit'>
</form>
</body>
</html>
这是我的路线
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res) {
res.render('index', { title: 'Express' });
});
router.post('/upload', function(req, res){
console.log(req.files);
});
module.exports = router;
这是我的app.js
var express = require('express');
var path = require('path');
var favicon = require('static-favicon');
var …我有问题上传文件nodejs.我读过 stack1 和 stack2.但我认为终端输出的这种不同情况如下:
