mongoDB数据库导入数据
利用mongoose创建数据库,基本操作
// 引入mongoose第三方模块 用来操作数据库 const mongoose = require('mongoose'); // 数据库连接 mongoose.connect('mongodb://localhost:27017/playground', { useNewUrlParser: true}) // 连接成功 .then(() => console.log('数据库连接成功')) // 连接失败 .catch(err => console.log(err, '数据库连接失败'));C // 创建集合规则 const courseSchema = new mongoose.Schema({ name: String, author: String, isPublished: Boolean }); // 使用规则创建集合 // 1.集合名称 // 2.集合规则 const Course = mongoose.model('Course', courseSchema) // courses // 创建文档 const course = new Course({ name: 'node.js基础', author: 'marco', isPublished: true }); // 向集合中插入文档 Course.create({name: 'Javascript', author: 'maoco', isPublished: false}, (err, result) => { console.log(err) console.log(result) }) // 将文档插入到数据库中 course.save();
2. mongoDB数据库导入数据
mongoimport –d 数据库名称 –c 集合名称 –file 要导入的数据文件
找到mongodb数据库的安装目录,将安装目录下的bin目录放置在环境变量中
找到mongoimport的安装目录
添加到系统环境变量
找到要导入数据的目录, user.json, 然后在改目录下打开命令终端,输入命令;mongoimport -d playground -c users -file ./user.json , 即可将数据导入数据库playground中的users集合中
user.json数据
