javascript - Mongoose 异常的事件名称

问题描述

我正在使用 winston 记录我的错误，但我遇到了一个死点。我在互联网上搜索，但我什么也没找到。也许你们可以在这里帮助我。

我有一个错误，我喜欢使用例如 process.on("Eventname", (ex) => { blah blah blah}) 来捕捉它

下面是我的错误：

node:internal/process/promises:246
          triggerUncaughtException(err, true /* fromPromise */);
          ^

MongooseServerSelectionError: connect ECONNREFUSED 127.0.0.1:27017

[nodemon] app crashed - waiting for file changes before starting...

这是我的日志文件：

const config = require("config");
require("express-async-errors");
const winston = require("winston");
require("winston-mongodb");

module.exports = function () {
  winston.handleExceptions(
    new winston.transports.File({ filename: "logs/uncaughtExceptions.log" })
  );

  process.on(**"Mongoose Event Name"**, (ex) => {
    console.log("WE GOT AN UNCAUGHT EXCEPTION");
    winston.error(ex.message, ex);
    process.exit(1);
  });

  process.on("unhandledRejection", (ex) => {
    throw ex;
  });

  winston.add(new winston.transports.File(), { filename: "logs/logfile.log" });
  winston.add(new winston.transports.MongoDB(), {
    db: config.get("mongoDB.connString"),
    level: "info",
  });
};

任何帮助都非常受欢迎

非常感谢您并继续编码！
