Mongoose添加验证Node-Demo连接方式

Mongoose添加验证Node-Demo连接方式

# mongodb://user:pwd@host/database-name?authSource=admin
mongodb://root:[email protected]:27017/school?authSource=admin

• 未添加 ?authSource=admin
  

• 添加后
  

• mongoose 验证连接方式

mongodb://root:[email protected]/Teacher?authSource=admin

// 导入模块
const mongoose = require("mongoose");
// 连接数据库
const db = mongoose.createConnection(
  "mongodb://root:[email protected]:27017/school?authSource=admin",
  // mongodb[协议]://user:password@host:port/database-name
  {
      useNewUrlParser: true, useUnifiedTopology: true },
  (err) => {
     
    if (err) {
     
      console.log("-------------------------------------");
      console.log("数据库连接失败: ", err);
      console.log("-------------------------------------");
    } else {
     
      console.log("数据库连接成功");
    }
  }
);
// 创建集合规则
const teacherSchema = new mongoose.Schema({
     
  // 教师: 课程 班级 上课周期 是否休假
  course: String,
  classroom: String,
  ontime: String,
  isSleep: Boolean,
});

// 使用规则创建集合 创建集合 Teacher，使用 teacherSchema 规则
const Teacher = mongoose.model("Teacher", teacherSchema);
// 创建集合实例
const teacher = new Teacher({
     
  course: "node.js",
  classroom: "1801",
  ontime: "12:00",
  isSleep: true,
});
