const MongoClient = require('mongodb').MongoClient; const assert = require('assert'); const url = 'mongodb://127.0.0.1:27017'; const dbName = 'jhblog'; MongoClient.connect(url, {useNewUrlParser:true}, function (err, client) { assert.equal(null, err); console.log('Connected successfully to server'); const db = client.db(dbName); db.collection("posts", function (err, collection) { var list = [ {title: "马里奥", tag:"game"}, {title: "node.js", tag:"it"} ]; collection.insert(list, function (err, result) { assert.equal(null, err); client.close(); }); }); });
