Question

我是mongodb的新手，正在使用 Express ， Body-Parser 和 Mongoose ，并且我有一个mongodb数据库（在线，它的调用mlab）我从中提取数据的地方。一切正常，我已经使用邮差来获取，发布和删除。我试图获取JavaScript中的数据，以便可以在html中显示。我正在使用Ajax，它可以工作并返回成功，但是会触发Ajax的fail功能。

exports.photoalbum_all = function (req, res, next) {
    PhotoAlbum.find(({}), function (err, photoalbum) {
    if (err) return next(err);
    res.send("../Views/images", {photo: photoalbum});
  });
};

mongodb模型

const mongoose = require('mongoose');
const Schema = mongoose.Schema, 
let PhotoAlbumSchema = new Schema({
title: String,
albums:[
         {
             u_name: String,
             u_title: String
         }]
},{
  timestamps: true
});

PhotoAlbumSchema.virtual('pictureId').get(function(){
  return this._id;
});

mongodb路线

const express = require('express');
const router = express.Router();
 //
// Require the controllers
const photoalbum_controller = 
require('../controllers/photoalbum.controller');
// 
router.get('/find', photoalbum_controller.photoalbum_all);

app.js

// app.js
const express = require('express');
const bodyParser = require('body-parser');
const photoalbum = require('./routes/photoalbum.route'); // Imports routes for the photos
//
const app = express();
//
// Set up mongoose connection
const mongoose = require('mongoose');
let dev_db_url = 'mongodb://Trex_son:Salvat1on1987@ds243254.mlab.com:43254/photoalbumdb';
let mongoDB = process.env.MONGODB_URI || dev_db_url;
mongoose.connect(mongoDB, { useNewUrlParser: true });
mongoose.Promise = global.Promise;
let db = mongoose.connection;
db.on('error', console.error.bind(console, 'MongoDB connection error:'));

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));

app.use('/photoalbums', photoalbum);
let port = 1234;
app.listen(port, () => {
console.log('Server is up and running on port number ' + port);
});

我不确定Ajax是检索此数据的最佳方法，是否有更好的方法将这些值检索到html
