node.js - Express Server 连续抛出 404 错误

问题描述

我不断收到这些错误。

这是我的一些代码。

  if (isNaN(port)) {
    // named pipe
    return val;
  }

  if (port >= 0) {
    // port number
    return port;
  }

  return false;
}

/**

function onError(error) {

  var bind = typeof port === 'string'

用户.js

const jwt = require('jsonwebtoken');
const router = express.Router();

const User = require('../models/user');

router.post("/profile", (req, res, next) => {

})

module.exports = router;

事件.js

var express = require('express');
var router = express.Router();

const Event = require('../models/event');
const checkAuth = require('../middleware/check-auth');

router.post("/createEvent", checkAuth, (req, res, next) => {
  const event = new Event({
    title: req.body.title,
    description: req.body.description,
    date: req.body.date,
    time: req.body.time,
    location: req.body.location,
    invite: req.body.invite,
    private: req.body.private
  });
  event.save()
    .then(result => {
      res.status(201).json({
        msg: "Event Created",
        rslt: result
      });
    })
    .catch(err => {
      res.status(500).json({
        err: err
      });
    });

});
module.exports = router;

关于我做错了什么的任何建议。这是我几个月前开始的一个项目，当然，还没有完成。我最近才回到它，似乎无法弄清楚为什么我的服务器无法工作。似乎与数据库连接良好。
