node+express上传图片

注意：别用multer 上传文件了，太坑了，普通文本获取不到，折腾了半天没有解决，最后采用 multiparty 解决了；

<!DOCTYPE html>
<html>
  <head>
    <title><%= title %></title>
    <link rel='stylesheet' href='/stylesheets/style.css' />
  </head>
  <body>
    <h1><%= title %></h1>
    <form action="/upload" method="post" enctype="multipart/form-data">
    <h2>单图上传</h2>
    <input type="file" name="logo">
<input type='text' name='username' value=''/>
<input type ='text' name = 'email' value =''/>
    <input type="submit" value="提交">
</form>
  </body>
</html>

var express = require('express');
var router = express.Router();
var multiparty = require('multiparty');
var fs = require('fs');

router.post('/upload',function(req,res,next){
    var uploadedPath;
    var dstPath;
    var form = new multiparty.Form({uploadDir: './public/images'});
    form.parse(req, function(err, fields, files){

        Object.keys(fields).forEach(function(name) {  //文本
            console.log('name:' + name+";filed:"+fields[name]);
        });


        Object.keys(files).forEach(function(name) {  //文件
            dstPath = 'public/images/'+new Date().getTime()+'-'+files[name][0].originalFilename;
            uploadedPath = files[name][0].path
        });
        fs.rename(uploadedPath, dstPath, function(err) {
            if(err){
                console.log('rename error: ' + err);
            } else {
                console.log('rename ok');
            }
        });

    })



})
