Node.js + Socket.io + Apache

Node.js + Socket.io + Apache

本文关键字:Apache io Socket Node js      更新时间:2023-09-26

我正在寻找一种集成Node.js + Socket的方法。io + Apache:我希望apache继续提供HTML/JS文件。我想要node.js监听端口8080上的连接。像这样:

var util = require("util"),
    app = require('http').createServer(handler),
    io = require('/socket.io').listen(app),
    fs = require('fs'),
    os = require('os'),
    url = require('url');
app.listen(8080);
function handler (req, res) {
    fs.readFile(__dirname + '/index.html',
  function (err, data) {
    if (err) {
      res.writeHead(500);
      return res.end('Error loading index.html');
    }
    res.writeHead(200);
    res.end(data);
  });
}
io.sockets.on('connection', function (socket) {
  socket.emit('news', { hello: 'world' });
  socket.on('my other event', function (data) {
    socket.emit('ok 1', { hello: 'world' });
  });
  socket.on('clientMSG', function (data) {
    socket.emit('ok 2', { hello: 'world' });
  });
});

如果我访问连接到此服务器的HTML,它可以工作,但我需要转到mydomian.com:8080/index.html。我想要的是能够登录mydomian.com/index.html。并且能够打开一个套接字连接:

<script>
        var socket = io.connect('http://mydomain.com', {port: 8080});
        socket.on('news', function (data) {
            console.log(data);
            socket.emit('my other event', { my: 'data from the client' });
        });
        socket.on('connect', function (data) {
            console.log("connect");
        });
        socket.on('disconnect', function (data) {
            console.log("disconnect");
        });

            //call this function when a button is clicked
        function sendMSG()
        {
            console.log("sendMSG"); 
            socket.emit('clientMSG', { msg: 'non-scheduled message from client' });
        }
    </script>

在这个例子中,我必须使用fs。当我去到URL中的8080端口时,readFile不工作。

有什么建议吗?谢谢大家。

从Apache端口80提供静态内容,并通过Socket提供动态/数据内容。8080端口上的IO服务器。你不需要app = require('http').createServer(handler)在你的插座。IO程序

Apache端口80 |-------------| 客户 |------------| 套接字。IO端口8080

var io = require('socket.io').listen(8080);
io.sockets.on('connection', function (socket) {
  io.sockets.emit('this', { will: 'be received by everyone'});
  socket.on('clientMSG', function (from, msg) {
    console.log('I received a private message by ', from, ' saying ', msg);
  });
  socket.on('disconnect', function () {
    sockets.emit('user disconnected');
  });
});

AWS + APACHE + NODEJS + SOCKET。IO + angularjs

服务器端


这在我的生产服务器上工作,运行apache端口80和NodeJS在端口8000上。用你想要的选项改变NodeJS端口…

  1. 为nodejs服务器的文件创建一个名为"nodejs"的文件夹,位于/var/www/html
  2. 在不同于80的端口上运行Nodejs,例如端口8000
  3. 执行命令:a2enmod proxy_http
  4. 执行a2enmod proxy_wstunnel
  5. 将接下来的两行放在以下文件的末尾:/etc/apache2/apache2.conf

    LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so
    LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so 
    
  6. 将接下来的12行放在以下文件的末尾:/sites-available/000-default.conf
    (如果你有自己创建的其他网站,把行放在那里)

    RewriteEngine On
    RewriteCond %{REQUEST_URI}  ^socket.io          [NC]
    RewriteCond %{QUERY_STRING} transport=websocket [NC]
    RewriteRule /{.*}       ws://localhost:8000/$1  [P,L]
    RewriteCond %{HTTP:Connection} Upgrade [NC]
    RewriteRule /(.*) ws://localhost:8000/$1 [P,L]
    ProxyPass /nodejs http://localhost:8000/
    ProxyPassReverse /nodejs http://localhost:8000/
    
    ProxyPass /socket.io http://localhost:8000/socket.io
    ProxyPassReverse /socket.io http://loacalhost:8000/socket.io
    ProxyPass /socket.io ws://localhost:8000/socket.io
    ProxyPassReverse /socket.io ws://localhost:8000/socket.io
    
  7. sudo service apache2 restart


客户端
我使用下面的库来实现Socket。在AngularJS中,但是我认为这个指南
对于socket的基本Javascript实现也很有用。输入输出技术。

调用PHP服务器:example.com
调用NodeJS服务器:example.com/nodejs
调用NodeJS Socket: example.com <——这个调用将默认由库

完成

希望能帮到你!

您可以继续从Apache提供页面,但您需要在node.js/socket.io中启用CORS:

index.html (from Apache)

<script src = "https://cdnjs.cloudflare.com/ajax/libs/socket.io/4.0.0/socket.io.js"></script>
<script>
   const socket = io("ws://your.domain.com:8080");
<script>

app.js (In nodejs):(启用CORS)

const express = require('express');
const app = express();
const http = require('http').Server(app);
const io = require('socket.io')(http, {
    cors: {
      origin: "*",
      methods: ["GET", "POST"]
    }
});
http.listen(8080);
