端口443上的Node.js + Express.js + Socket.io（HTTPS TLS / SSL） [英] Node.js + Express.js + Socket.io on port 443 (HTTPS TLS/SSL)

问题描述

我有一个带有Node.js，Express.js和Socket.io的应用程序，使用除443之外的任何端口运行良好。服务器只能在HTTPS端口443上运行，同样，websocket也应加密。

I have an app with Node.js, Express.js, and Socket.io that runs fine using ANY port except 443. The server is meant to only operate over HTTPS port 443 and likewise, the websocket should be encrypted as well.

CODE THAT WORKS

var fs = require('fs');
var https = require('https');
var express = require('express');
var socket = require('socket.io');
var sslOptions = {
    key: fs.readFileSync(__dirname + '/../ssl/server.key,
    cert: fs.readFileSync(__dirname + '/../ssl/server.pem,
    ciphers: 'ECDHE-RSA-AES256-SHA:AES256-SHA:RC4-SHA:RC4:HIGH:!MD5:!aNULL:!EDH:!AESGCM',
    honorCipherOrder: true
};

var app = express();
var server = https.createServer(sslOptions, app);
var io = socket.listen(server, {
    "log level" : 3,
    "match origin protocol" : true,
    "transports" : ['websocket']
});
server.listen(8443);

当我将端口（最后一行）更改为443时，节点服务器立即崩溃并出现错误：

When I change the port (last line) to 443, the Node server crashes right away with an error:

warn: error raised: Error: listen EADDRINUSE

推荐答案

显然你已经有一台服务器正在监听你机器上的那个端口。你有可能吗？在其他地方启动此服务器并且它仍在运行？

Apparently you've already got a server listening on that port on your machine. Is is possible that you started this server elsewhere and it's still running?
