formidable实现node.js中的文件上传
效果图
核心代码
var express = require("express");
var formidable = require('formidable');
var util = require("util");
var app = express();
app.engine('htm', require('express-art-template')) //设置模板引擎
app.get("/", function(req, res) {
res.render('index.htm');
})
app.post('/dopost', function(req, res) {
var form = new formidable.IncomingForm(); //获取formidable对象
form.uploadDir = "./uploads"; //指定上传文件夹（必须提前手动创建）
form.keepExtensions = true; //保持拓展名不变
form.parse(req, function(err, fields, files) {
res.send('ok');
});
})
app.listen(3000, function() {
console.log("run server____");
})html代码
