javascript - multer无法进行文件上传？

问题描述

问 题

在使用multer中间件时无法进行文件的上传。
js代码：

var express = require('express');
var router = express.Router();
var multer  = require('multer');
var upload = multer({ dest: 'uploads' });
router.get('/', function(req, res, next) {
    res.render('input1');
});
router.post('/upload', upload.single('avatar'),function (req,res,next) {

});
module.exports = router;  

form代码：

form(enctype="multipart/form-data" action='/upload' method="POST")
        .form-group(align='center')
            input.btn(type='file' value='请选择文件' name='avatar')
            input.btn(type='submit' value='上传')

解决方案

已经解决 是因为express渲染路由的逻辑没有搞清楚
