Question

我最近尝试将SSL证书安装到我的服务器上。证书文件（privkey.pem，fullchain.pem）位于应用程序的根目录中。当我运行以下代码时：

var express = require('express');
var app = express();
var helmet = require('helmet');
var db = require('./server/database.js');
var fs = require('fs');
var ssl = require('ssl-root-cas');

'use strict';
var rootCas = require('ssl-root-cas/latest').create();

// default for all https requests
// (whether using https directly, request, or another module)
require('https').globalAgent.options.ca = rootCas;

app.use(helmet()); 

var options = {
    key : fs.readFileSync('privkey.pem', 'ascii'),
    cert : fs.readFileSync('fullchain.pem', 'ascii')
}

app.get('/', function(req, res) {
    res.sendFile(__dirname + '/public/index.html');
});
app.use('/public', express.static(__dirname + '/public'));

var serv = require('https').createServer(options, app);

服务器运行时没有错误。 “服务器正在侦听端口80”确认我添加了节目，证书似乎没有引起任何直接问题。但是，当我尝试连接到域时（使用https：//），Chrome会使用ERR_CONNECTION_REFUSED进行响应。通过http连接到域时，Chrome会使用相同的消息进行响应。我正在使用SocketIO，它稍后在代码中初始化，我没有在我的问题和SocketIO的函数之间找到任何连接。是什么导致无法连接？

https请求通过端口443而不是80发送。以下代码没有问题：

var express = require('express');
var app = express();
var helmet = require('helmet');
var db = require('./server/database.js');
var fs = require('fs');
var ssl = require('ssl-root-cas');

'use strict';
var rootCas = require('ssl-root-cas/latest').create();

// default for all https requests
// (whether using https directly, request, or another module)
require('https').globalAgent.options.ca = rootCas;

app.use(helmet()); 

var options = {
    key : fs.readFileSync('privkey.pem', 'ascii'),
    cert : fs.readFileSync('fullchain.pem', 'ascii')
}

app.get('/', function(req, res) {
    res.sendFile(__dirname + '/public/index.html');
});
app.use('/public', express.static(__dirname + '/public'));

var serv = require('https').createServer(options, app);
//var serv = require('https').Server(app); //DEBUG ONLY

Javascript http服务器：ERR_CONNECTION_REFUSED
