我使用的是 node v0.10.26和express v4.2.0，我对node还很陌生.在过go 的三个多小时里，我一直在用我的头敲打我的办公桌，试图用node获得一份文件上传表单.在这一点上，我只是想得到更多.不返回未定义的文件.我的观点是这样的
<!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>
这是我的路由
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apply.js
var express = require('express');
var path = require('path');
var favicon = require('static-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var routes = require('./routes/index');
var users = require('./routes/users');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'hjs');
app.use(favicon());
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', routes);
app.use('/users', users);
/// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
/// error handlers
// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err
});
});
}
// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {}
});
});
module.exports = app;
我在某个地方看到，包括methodOverride()和bodyParser({keepExtensions:true,uploadDir:path})应该会有所帮助，但如果我添加这些行，我甚至无法启动服务器.
