Question

简短描述 在NodeJS中使用群集 - ＆gt; net.createServer - ＆gt; Socket.IO，如何在发送给worker之前获取头文件或连接字符串？

详细说明 我有4个服务器，每个服务器运行8个CPU。使用负载均衡器和集群，我将获得32个节点+4个主节点。

负载均衡器将使用ip地址来确定它将使用的服务器。运行Unity Socket.IO否则我想使用JSESSIONID。当连接到达主节点时，它会在ip上查找以确定要使用的集群。

在这里，我真的想要使用其他东西，或者所有连接（或大多数）将在同一个群集上。所以使用连接字符串唯一ID或cookie。

连接时我在连接字符串中添加一个唯一值？unique = {guid}但是当到达主节点时，我无法获取此数据（或cookie /标题）。

// THIS IS MASTER NODE

var server = net.createServer({ pauseOnConnect: true }, function (connection) {

    // HOW TO GET headers or URL from connection?

    // Incoming request processing
    var remote = connection.remoteAddress;
    var local = connection.localAddress;
    var cIp = remote + local;
    var ip = cIp.match(/[0-9]+/g)[0].replace(/,/g, '');
    var wIndex = ip % num_processes;

    // here we get the worker
    var worker = workers[wIndex];

    logger.log("Message to work "+ worker+", remote: "+ remote+ ", local: "+ local+", ip: "+ ip +", index: "+ wIndex);
    worker.send('sticky-session:connection', connection);

});


// THIS IS A WORKER NODE

process.on('message', function(message, connection) {
    if (message !== 'sticky-session:connection') {
        return;
    }

    // Emulate a connection event on the server by emitting the
    // event with the connection the master sent us.
    http.emit('connection', connection);

    connection.resume();
});

我试图在“数据”中捕获信息。但随后聊天就停止了。

connection.on('data', function (data) {

    /* WHERE I GET OUTPUT OF 

    GET /chat HTTP/1.1
    Host: 127.0.0.1:5223
    Connection: keep-alive
    Cache-Control: max-age=0

    */
    console.log(data.toString('utf8', 0, data.length));


    // BUT THE CHAT WONT WORK
});

NodeJS Socket.io Sticky-Session缺少标题
