连接数据库

const mongoose = require('mongoose')
    const {  Schema } = mongoose
    //连接数据库（library），如果该数据库不存在则自动添加
    mongoose.connect('mongodb://localhost:1270/library', {  useNewUrlParser: true, useUnifiedTopology: true });
    //建表
    const userSchema = new Schema({ 
      u_Type: { 
        type: String
      },
      u_Name: { 
        type: String
      },
      u_No: { 
        type: Number,
        // unique: true
      },
      u_Password: { 
        type: String
      },
      b_limit: { 
        type: String
      },
      b_Massage: { 
        type: Array
      }
    })
     const User = mongoose.model('User', userSchema)
