我目前正在学习在 nodejs 的上下文中进行日志记录。目前我的设置使用 morgan 作为快速中间件，winston 作为我的日志记录。我的问题是摩根使用什么级别的日志记录？到目前为止，这是我的 appjs。我正在尝试决定如何拆分我的日志记录。

import bodyParser from "body-parser";
import express from "express";
import helmet from "helmet";
import morgan from "morgan";
import path from "path";
import { logger, stream } from "./utils/logger";
import es from "./esClient";

const app = express();

app.use(helmet());
app.use(morgan("combined", { stream }));
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

export default app;

这是我导入的记录器文件

import winston from "winston";
import path from "path";

winston.emitErrs = true;

const logger = new winston.Logger({
  transports: [
    new winston.transports.File({
      level: "info",
      name: "info",
      filename: path.join(__dirname,"..","..","logs/access.log"),
      json: true,
      maxsize: 5242880, //5MB
      maxFiles: 5,
      colorize: true
    }),
    new winston.transports.File({
      level: "verbose",
      name: "elasticsearch",
      filename: path.join(__dirname,"..","..","logs/elasticsearch.log"),
      json: true,
      maxsize: 5242880, //5MB
      maxFiles: 5,
      colorize: true
    }),
    new winston.transports.File({
      level: "error",
      name: "error",
      filename: path.join(__dirname,"..","..","logs/errors.log"),
      json: true,
      maxsize: 5242880, //5MB
      maxFiles: 5,
      colorize: true
    }),
    new winston.transports.Console({
      colorize: true,
      level: "warning"
    })
  ]
});

const stream = {
  write: function(message, encoding){
    logger.info(message);
  }
};

export { logger, stream };

编辑：为澄清起见，我不希望将我的 http 请求日志记录到我的数据库日志中。有没有办法做到这一点？
