Winston: JSON 的循环结构：Sequelize 日志记录

创建于 2017-11-05 · 3评论 · 资料来源: winstonjs/winston

代码：

const winston = require('winston');

const sequelize = new Sequelize(config.db.database, config.db.username, config.db.password, {
    host: config.db.host,
    dialect: config.db.dialect,
    logging: winston.info // Not work it
});

版本：

winston: 3.0.0-rc1
sequelize: 4.22.2
mysql2: 1.4.2

错误堆栈：

我相信这与续集而不是温斯顿有关。
我们在将 sequelize 升级到版本 4 后遇到了这个问题。
我认为，从这个版本开始，使用两个参数 sql 和一些 sequelize 对象（我不记得对象到底是什么）调用了一个日志记录函数。 winston 尝试记录传递的每个参数，因此它也尝试了 sequelize 对象，什么不打算记录。

要解决此问题，请尝试将 winston 日志调用包装到另一个函数中。

const winston = require('winston');

const sequelize = new Sequelize(config.db.database, config.db.username, config.db.password, {
    host: config.db.host,
    dialect: config.db.dialect,
    logging: function(sql, sequelizeObject) {
        winston.info(sql); // Not work it
    }
});
