問題描述

這段代碼報錯var queryAll = user_model.find();，不知道這段代碼錯在哪兒，麻煩有經驗的人幫忙看哈，

// login actionconst express = require(’express’);var mongoose = require(’mongoose’);var User_Model = mongoose.model(’User_Model’);const router = express.Router();router.get(’/’,(req,res,next)=>{ res.render(’login.html’);});module.exports=router;router.post(’/’,(req,resp,next)=>{ debugger; //連接數據庫 mongoose.connect(’mongodb://127.0.0.1:27017/likeread’,(err)=>{if(err) console.log(’err’); }); console.log(mongoose); var user_model = new User_Model(); debugger; //查找數據 var queryAll = user_model.find({}); queryAll.exec((err,result)=>{if(err){ console.log(err);}else{ console.log(result);} }); debugger; user_model.close((err,res)=>{if(err){ console.log(err);} }); debugger; resp.end();});

問題解答

var queryAll = User_Model.find({});
