迭代对象数组，并将每个对象保存到 MongoDB

Question

在从 Facebook 端点接收到每个对象后，我想将数组中的每个对象保存/插入到我的 MongoDB 中。

如何遍历返回的对象数组，然后将其保存到我的 mongoDB？ :)

来自我的 Route 的代码，我使用 superagent 从 Facebook API 接收数据

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;

每个对象如下所示：

"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/架构

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)

我尝试过但还没有成功

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

您可以遍历数组，然后批量执行所有对象。

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();
