Socket.IO 无法通过 https 连接 [英] Socket.IO can't connect through https
本文介绍了Socket.IO 无法通过 https 连接的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个使用 socket.IO 的 node.js 应用程序.它在 http 上运行良好,但是当尝试通过 https 连接到套接字时 - 没有任何反应.
这是代码的一部分:
I have a node.js app, that uses socket.IO. It works fine on http, but when trying to connect to the socket through https - nothing happens.
Here's some part of the code:
var fs = require('fs');
var ioHttp = require('socket.io').listen(8899, {
'flash policy port': -1
});
initSocket(ioHttp);
var ioHttps = require('socket.io').listen(8895, {
key: fs.readFileSync('/path/to/file/file.key'),
cert: fs.readFileSync('/path/to/file/file.crt'),
ca: [
fs.readFileSync('/path/to/file/sub.class1.server.ca.pem'),
fs.readFileSync('/path/to/file/ca.pem')
],
'flash policy port': -1
});
initSocket(ioHttps);
和 initSocket
函数:
function initSocket(io) {
io.enable('browser client minification');
io.enable('browser client etag');
io.enable('browser client gzip');
io.set('transports', [
'websocket',
'htmlfile',
'flashsocket',
'jsonp-polling'
]);
io.sockets.on('connection', function (client) {
//the connnection is handled here
});
}
客户端连接如下:
var secureConnection = false;
var port = 8899;
if (window.location.protocol === 'https:') {
port = 8895;
secureConnection = true;
}
var socket = io.connect('domain.org', {port: port, secure: secureConnection});
正如我所说的,在 http 上一切正常,但在 https 上连接却给我连接被中断".我做错了什么?
As I said everything works fine on http, but connecting on https gives me "The connection was interrupted". What am I doing wrong?
推荐答案
你不能像 https
服务器那样初始化 socket.io
服务器.您必须启动一个单独的 https 服务器,然后将 socket.io 服务器连接到它.
You cannot initalize socket.io
server like https
server. You have to start a separate https server and then attach socket.io server to it.
var https = require('https'),
fs = require('fs');
var options = {
key: fs.readFileSync('ssl/server.key'),
cert: fs.readFileSync('ssl/server.crt'),
ca: fs.readFileSync('ssl/ca.crt')
};
var app = https.createServer(options);
io = require('socket.io').listen(app); //socket.io server listens to https connections
app.listen(8895, "0.0.0.0");
