为什么我的本地主机服务器不接受此端口号？

Question

I have a hapi.js code as below: ` 'use strict';

const hapi = require("hapi");

const server = new hapi.Server();

server.connection({
    host: 'localhost',
    port: 2922,
});

server.route({
    method: 'GET',
    path: '/hello',
    handler: function (req, res) {
                    res('Hello world from hapi.js');
    }
});

server.start((err) => {
});

` The problem is that when I run this server with port number 22291 it executes and exit immediately without any error, What is the reason for? I am using linux centos 7

You need to check for the error in the start callback:

server.start((err) => {
   if (err) throw err;
});

That will give you the details you need to debug. Always make sure to check for errors in callbacks or you'll repeatedly run into this problem in Node.
