實行一個圖片上傳和表單數(shù)據(jù)的提交，但是出了點問題

可行模式

const router = require('koa-router')();
const controller = require('../controller/user');
const multer = require('koa-multer');

var storage = multer.diskStorage({
        //文件保存路徑  
        destination: function(req, file, cb) {
            cb(null, 'static/images/')
        },
        //修改文件名稱  
        filename: function(req, file, cb) {
            var fileFormat = (file.originalname).split(".");
            cb(null, Date.now() + "." + fileFormat[fileFormat.length - 1]);
        }
    })
    //加載配置  
var upload = multer({ storage: storage });

router.post('/userInsertInto', upload.single('file'), async(ctx, next) => {
    console.log(ctx.req.body)
    let data = JSON.parse(ctx.req.body.data);
    console.log(data);
    ctx.body = {
        msg: "aa"
    }
})

module.exports = router;

require,module.exports 模式

require

const router = require('koa-router')();
const controller = require('../controller/user');

router.post('/userInsertInto', controller.userInsertInto)


module.exports = router;

module.exports

const router = require('koa-router')();
const userModel = require('../mysql/mysql');
const multer = require('koa-multer');

var storage = multer.diskStorage({
        //文件保存路徑  
        destination: function(req, file, cb) {
            cb(null, 'static/images/')
        },
        //修改文件名稱  
        filename: function(req, file, cb) {
            var fileFormat = (file.originalname).split(".");
            cb(null, Date.now() + "." + fileFormat[fileFormat.length - 1]);
        }
    })
    //加載配置  
var upload = multer({ storage: storage });

const userInsertInto = async (ctx) => {
    await upload.single('file');
    console.log(ctx.req.body)
    let data = JSON.parse(ctx.req.body.data);
    ctx.body = {
        msg: "aa"
    }
}

module.exports = {
    userInsertInto: userInsertInto
}
