mongodb 遇到問題-查詢單個需要封裝id

標籤：url   name   color   DBName   _id   status   col   param   objectid   

mongodb，get字元查詢需要傳入特定的封裝id才能識別

 1 const ObjectID = require(‘mongodb‘).ObjectID 2  3 exports.queryOne = (req, res) => { 4     console.log(req.body) 5     MongoClient.connect(url, function(err, client) { 6             assert.equal(null, err); 7             const db = client.db(dbName); 8             // Get the documents collection 9             const collection = db.collection(‘documents‘);10             const id = new ObjectID(req.params.id)11             console.log(id)12             // Find some documents13             collection.find({‘_id‘:id}).toArray(function(err, docs) {14                 assert.equal(err, null);15                 res.status(200).json(docs)16                 client.close();17             });18         });19     }
