迭代对象数组，并将每个对象保存到MongoDB

Question

我想在从Facebook端点接收数据后，将每个对象从数组保存/插入到我的MongoDB中。

我将如何遍历返回的对象数组，然后将其保存到我的mongoDB？ :)从我的路线，在那里我从Facebook的API接收数据用的SuperAgent

代码

var express = require('express'); 
var router = express.Router(); 
var request = require('superagent') 
var utils = require('../utils') 

router.get('/facebook', function(req, res, next) { 

    var url = "https://graph.facebook.com/v2.9/xxxxxxxx" 

    request 
    .get(url) 
    .set('Accept', 'application/json') 
    .end(function(err, result){ 
     var parse = JSON.parse(result.text) 
     res.json({ 
     confirmation: 'success', 
     response: parse 
     }) 
    }); 

}); 

module.exports = router; 

每个对象看起来像这样：

"confirmation": "success", 
"response": { 
"data": [ 
{ 
"message": "Søger et godt hjulsæt til Max 1000\nkr.1,000 - Løsning, Vejle, Denmark\n\nVed at ser er en masse fine hjulsæt er er i overskud der ude er der nogen der har et rigtig fint hjulsæt i vil sælge mig ?",

我的模型/ Schema

var mongoose = require('mongoose') 

var FeedSchema = new mongoose.Schema({ 
    type: {type: String, default: ''}, 
    title: {type: String, default: ''}, 
    image: {type: String, default: ''}, 
    description: {type: String, default: ''}, 
    timestamp: {type: Date, default: Date.now} 
}) 

module.exports = mongoose.model('FeedSchema', FeedSchema) 

我曾尝试，但没有工作尚未

var express = require('express'); 
var router = express.Router(); 
var request = require('superagent') 
var utils = require('../utils') 
var Feed = require('../models/Feed') 

router.get('/facebook', function(req, res, next) { 

    var url = "https://graph.facebook.com/v2.9/XXXXXXX" 
    var bulk = Feed.initializeUnorderedBulkOp(); 

    request 
    .get(url) 
    .set('Accept', 'application/json') 
    .end(function(err, result){ 
     var parse = JSON.parse(result.text) 

     var object = parse.data 

     array.forEach((object) => { 
     bulk.insert({ 
      type: object.type, 
      title: object.title, 
      image: object.image, 
      description: object.description 
     }) 
     }) 
     bulk.execute(); 
    }); 


}); 

module.exports = router; 

Answer 1

可以迭代这个数组，然后bulk.execute所有对象。

var bulk = db.items.initializeUnorderedBulkOp(); 
array.forEach((object) => { 
    bulk.insert({ 
    type: object.type, 
    title: object.title, 
    image: object.image, 
    description: object.description, 
    timestamp: object.timestamp 
    }) 
}) 
bulk.execute();
