如何在 Node.js 中使用 express-winston 将日志存储到 mysql 数据库中

how to store logs into mysql db using express-winston in Node.js

我正在尝试在 Node.js.

中使用 express-winston 将日志存储到 mysql db(使用 Sequelize)

根据文档(https://www.npmjs.com/package/winston-sql-transport),我应该执行以下操作:

const { Logger } = require('winston');
const { SQLTransport } = require('./../lib/winston-sql-transport');   
 
const logger = new Logger({
  transports: [
    new SQLTransport({
      tableName: 'winston_logs',
    })]
});
 
module.exports = logger;

我在 app.js 中应用了上面的代码,但没有成功。

app.js

const { SQLTransport } = require('./../lib/winston-sql-transport'); // //Error: Cannot find module './../lib/winston-sql-transport'

const mysqlOption =  {
   tableName: 'winston_logs'
}

app.use(
  expressWinston.logger({
    transports: [
      new SQLTransport(mysqlOption)
    ],
    format: winston.format.combine(
      winston.format.timestamp({ format: timezoned }),
      winston.format.json(),
    ),
    metaField: null,
    expressFormat: true, 
    statusLevels: false,
    level: function (req, res) {
      var level = "";
      if (res.statusCode < 400) { level = "info"; }
      if (res.statusCode >= 400) { level = "warn"; }
      if (res.statusCode >= 500) { level = "error"; }
      return level;
    }
  })
)

我尝试将导入更改为 const { SQLTransport } = require('winston-sql-transport');
产生的错误:

Error: You have to define client

at new SQLTransport (/server/node_modules/winston-sql-transport/lib/winston-sql-transport.js:40:13)

我发现很少有人谈论这个包。
所以我想知道有没有什么办法可以做到?

更新 1:

我按照评论

的建议更新了mysqlOption
const { SQLTransport } = require('winston-sql-transport'); 

const mysqlOption =  {
  tableName : "winston_logs",
  client: 'mysql',
  connection: {
    host: '127.0.0.1:3306',
    user: 'root',
    password: '',
    database: 'mydb'
  }
}

日志成功出现在控制台中,但我的数据库中没有存储任何内容。

更新 2:
由于我使用的是 Sequelize,因此我将为日志提供架构 table

// See http://docs.sequelizejs.com/en/latest/docs/models-definition/
// for more of what you can do here.
const Sequelize = require('sequelize');
const DataTypes = Sequelize.DataTypes;

module.exports = function (app) {
  const sequelizeClient = app.get('sequelizeClient');
  const logs = sequelizeClient.define('winston_logs', {
    id: {
      type: DataTypes.INTEGER(10),
      allowNull: false,
      autoIncrement: true,
      primaryKey: true
    },
    level: {
      type: DataTypes.STRING(45),
      allowNull: false
    },
    message: {
      type: DataTypes.TEXT,
      allowNull: false
    },
    meta: {
      type: DataTypes.STRING(255),
      allowNull: false
    },
    hostname: {
      type: DataTypes.STRING(255),
      allowNull: false
    },
    timestamp: {
      type: DataTypes.DATE,
      allowNull: false
    },
  }, {
    hooks: {
      beforeCount(options) {
        options.raw = true;
      }
    }
  });

  logs.associate = function (models) {
  };

  return logs;
};

最终放弃将日志存储在 mysql 数据库中,因为 mysql 传输包似乎有点过时了。

相反,我使用 winston-daily-rotate-file
在本地存储日志 可以设置旋转频率,最大文件大小等
