Node.js,socket,io和HTTPS

标签: node.js https

我正在制作白板应用:

var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);

io.on('connect', function(socket) {
  socket.on('join', function(data) {
    socket.join(data.room);
    console.log(data.room);
  });

  socket.on('drawing', function(data) {
    console.log(data);
    io.sockets.in(data.room).emit("senddraw", data);
  });

  socket.on('writetext', function(data) {
    console.log(data);
    io.sockets.in(data.room).emit("senddraw", data);
  });

  socket.on('action', function(data) {
    console.log(data);
    io.sockets.in(data.room).emit("action", data);
  });

});

http.listen(8080, function() {
  console.log('listening on localhost:8080');
});

如果我在服务器上运行此节点脚本,我可以通过我的网页的localhost副本进行连接。但是,由于它是通过HTTPS提供的,因此无法从我服务器上托管的副本进行连接。我收到错误:

polling-xhr.js:264混合内容:*****上的页面是通过HTTPS加载的,但是请求了一个不安全的XMLHttpRequest端点'http:// < /strong>..*:8080/socket.io/?EIO=3&transport=polling&t=Lu2NoGL”。此请求已被阻止;内容必须通过HTTPS提供。

如何在不禁用服务器上的ssl的情况下解决此问题?

客户端具有以下内容:

  //var socket = io.connect("http://localhost:8080");
  var socket = io.connect("http://**.***.***.**:8080");

  socket.on("connect", function(data) {
    socket.emit("join", {room : "@roomid"});
  });

关于绘制事件:

socket.emit("drawing", {x0 : x0, y0 : y0, x1 : x1, y1: y1, current : current, room : "@roomid"});

选择的是:

socket.on("drawing", function(data) {do blah});

您需要通过连接到socket.io client而不是/来更改网页javascript中的http://...*:8080代码:

var socket = io.connect('/');

我在使用 socket.io 的通知实现中解决了这个问题

我的 socket.io 服务器(节点)在 8001 端口上

我的应用程序使用 ssl 并通过 https 提供服务

大致步骤:

1. using reverse proxy in my virtualhost apache configurations to point all socket.io requests to my node server at 8001
2. sending requests from socket.io client to host = wss://domain.com:443/
3. using same version i.e. 4.0.0 of socket.io client and socket.io server

我使用的反向代理配置:

        RewriteEngine On
        RewriteCond %{REQUEST_URI}  ^/socket.io            [NC]
        RewriteCond %{QUERY_STRING} transport=websocket    [NC]
        RewriteRule /(.*)           ws://localhost:8001/$1 [P,L]

        ProxyPass /socket.io http://localhost:8001/socket.io connectiontimeout=600 timeout=600
        ProxyPassReverse /socket.io http://localhost:8001/socket.io

使用本指南: https://www.serverlab.ca/tutorials/linux/web-servers-linux/how-to-reverse-proxy-websockets-with-apache-2-4/

socket.io 客户端实现:

function createSocket(host) {
        return io(host);
    }
    function init() {
        var host = "wss://mydomain.com:443/";
        try {
            socket = createSocket(host);
            console.log('3');

            socket.on("connect", () => {
                console.log('In Connect');
            });

socket.io 服务器实现

const app = require("express")();
const server = require("http").createServer(app);

const io = require("socket.io")(server, {
cors: {
origin: '*',
}, 'pingTimeout': 180000, 'pingInterval': 25000,
});

io.on("connection", (socket) => {
  console.log("Connected!");
  socket.on("message", data => {
              console.log("in message with data: "+data.topic);
              pubClient.publish('notification', data);
            });
});

server.listen(8001);
