egg 连接mysql 在mysql 插入数据

1。配置mysql

exports.mysql = {
　　　　enable: true,
　　　　package: 'egg-mysql'

};

　　

'use strict';
module.exports = appInfo => {
  const config = exports = {};
  // use for cookie sign key, should change to your own and keep security
  config.keys = appInfo.name + '_1551971762613_5533';
  // add your config here
  config.middleware = [];
  config.mysql = {
    client: {
      host: 'localhost',
      port: '3306',
      user: 'root',
      password: 'root',
      database:'cms-api'
    }
  },
  config.security= {
    csrf: {
      enable: false,
    }
   }
  return config;
};

2.services

user.js

const Service = require('egg').Service;
class UserService extends Service {
    async create(user)  {
        let {app}=this;
        let  result = await app.mysql.insert('user',
             user
           );
        return  result;
     }

}
module.exports = UserService;

3.Controller

user.js

const Controller = require('egg').Controller;

class UserController extends Controller {
  async create() {
    const { ctx,service} = this;
    let  user  =ctx.request.body;
    let  result  = await  service.user.create(user);
    console.log(result);
    this.ctx.body=result;
    if(result.affectedRows === 1)  {
        this.ctx.body ={
            code:0,
            data:result.insertId
        }
    }else {
      this.ctx.body ={
        code:1,
        data:'用户添加失败'
    }
    }
  } 
}

module.exports = UserController;

/ 判断插入成功
const insertSuccess = result.affectedRows === 1;

result的打印解果

OkPacket {
  fieldCount: 0,
  affectedRows: 1,
  insertId: 0,
  serverStatus: 2,
  warningCount: 0,
  message: '',
  protocol41: true,
  changedRows: 0 }
