当我尝试在multer中上传图片时没有反应

Question

当我尝试使用multer上传图像时，我没有从节点服务器得到任何响应

const express = require('express')
var router = express.Router()
var multer = require('multer')


var upload = multer({
    dest: appRoot + '/uploads/photo'
})


router.post('/upload', upload.single('photo'), function (req, res, next) {
    var fileinfo = req.file;
    res.send(fileinfo);
})


module.exports = router
