我想要实现的是从我的mongoDB查询objectID到我的nodeJS然后通过我的本地主机检索它 http://localhost:3000/objectSearch?objectid=
我谷歌一切,我只是想不出来。如果有人会完成这个例子,那么我可以看看它是如何工作的,谢谢! :d
**objectSearch.js**
var express = require('express');
var router = express.Router();
var mongodb = require('mongodb');
var MongoClient = mongodb.MongoClient;
var objectID = require('mongodb')
var url = 'mongodb://localhost:27017/WishList';
router.get("/", function (err, db) {
if (err) {
console.log("unable to connect to server", err);
} else {
console.log("Connect to server");
var collection = db.collection('orders');
var _id = req.query.id
collection.findOne({_id: mongodb.ObjectID(_id)}, function (err, result) {
if (err || !result) {
res.render('error', {error: "No records found with that id"});
} else {
res.render(
'objectSearch',
{
objectSearch: result,
title: result
})
}
})
}
})
module.exports = router;
ObjectSearch.ejs

答案 0 :(得分:0)
您在网址上的参数不是id
,而是objectid
,因此您的代码行应为:
req.query.objectid
