如何配置Socket.io在https上的同一端口上运行？

Question

一如既往,我一直在搜索我的手指血腥找到我的问题的答案,所以我再次接触你所有的天才!:)

我已经使用socket.io(使用express)设置了一个Node.js服务器,它使用端口8443运行良好.它运行:).由于我的许多客户似乎不允许端口8443上的流量,因此他们无法使用我的服务.

我想知道如何在端口443上设置Node.js,因为使用Node-server的站点已经在使用此端口(Https).如果我尝试在我的节点服务器上使用端口443我得到:warn - 引发错误:错误:听EACCES

我的Node-js代码的一部分:

var fs = require('fs');
var https = require('https');
var express = require('express');
var socket = require('socket.io');
var port = 8443;

var sslOptions = {
  pfx: fs.readFileSync('mykey.pfx'),
     passphrase: ********
};

var app = express();

app.all('/*', function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE,OPTIONS');
  res.header('Access-Control-Allow-Headers', 'Content-Type, Authorization, Content-Length, X-Requested-With, *');
  next();
});

var server = https.createServer(sslOptions, app);

var io = socket.listen(server, {
    "log level" : 1,
    "match origin protocol" : true,
    "transports" : ['websocket', 'flashsocket'
   , 'xhr-polling'
   , 'jsonp-polling']
});

//No need to list all my socket events I guess

server.listen(port);

连接到我的节点服务器的客户端代码:

var socket = io.connect("https://www.*MYWEBSITE*.com", { secure: true, port: 8443});

我想你在这里问了几个不同的问题.我将自己回答第一个,它应该解决你原来的问题,但其他一些人提出了一些值得了解的方便的部署选项.

首先,您不需要在它自己的端口上运行socket.io服务器.您可以让socket.io服务器将自己绑定到Express应用程序.例如:

// ... require stuff
var app = express();

// ... set up your express middleware, etc

var server = https.createServer(sslOptions, app);
// attach your socket.io server to the express server
var io = require("socket.io").listen(server);
server.listen(port);

无论您如何设置节点应用程序,都值得知道如何将nginx设置为反向代理.这很好,因为您在运行节点应用程序时不必是root用户端口<1024,并且可以通过虚拟主机将许多应用程序绑定到同一IP地址.

这是一个nginx服务器配置块,它将反向代理节点应用程序(并支持websockets).

server {
    listen 80;
    server_name app.com www.app.com # a list of hosts for this application
    access_log /var/log/nginx/access/app.log; # you'll need to create /var/log/nginx/access
    error_log  /var/log/nginx/error/app.log; # and you'll need to create /var/log/nginx/error

    # prevents 502 bad gateway error

        proxy_redirect off;
    }
