mongoose 连接数据库操作 DeprecationWarning: current URL string parser is deprecated

Posted 2020-12-15 montai

moogoose 数据库操作是这样的:

//添加模块

const mongoose = require(‘mongoose‘);

//链接数据库{useNewUrlParser: true, useUnifiedTopology: true}

mongoose.connect(‘mongodb://localhost:27017/test‘, {useNewUrlParser: true, useUnifiedTopology: true});
//创建model, parse 很简单 只有一个name 值{ name: String }
const Cat = mongoose.model(‘Cat‘, { name: String });
//创建数据源
const kitty = new Cat({ name: ‘Zildjian‘ });
//插入数据
kitty.save().then(() => console.log(‘meow‘));

将红色字体部分,添加到代码中,就不会再出现下面的问题了
