1.开启 mongodb
StartMongo2.开启 端口(控制台)
startManager3.查看数据库
use eduline4.查看数据表
show collections5.查看表数据
db.users.find()

db.users.ensureIndex({"email":1},{"unique":true,"name":"emailuiq"})
db.users.ensureIndex({"nicheng":1},{"unique":true,"name":"nichenguiq"})

// 5.实例化 user
let user = new User(); // 因为user是关键词,当插入时,没有表会自动生成一个表,表名是users
// 6.保存参数
user.email = this.request.body['email'];
