Node.js上传文件

var formidable = require('formidable');
var util = require('util');

exports.upload = function(req,res){
    var form = new formidable.IncomingForm();
    form.encoding = 'utf-8';
    form.uploadDir = "E:/file/upload";//目录需要已存在
    /**
     * fields 表单中的其他属性
     * files  文件集合
     */
    form.parse(req, function(err, fields, files) {
        res.writeHead(200, {'content-type': 'text/plain'});
        res.write('received upload:\n\n');
        res.end(util.inspect({fields: fields, files: files}));
    });
}

上传后显示：
