Socket.io - 客户端断开后手动重新连接

Question

I use node.js and socket.io to create a real time web application. I will give the users full control of the socket connection, like manual disconnect and (re)connect.

function socket_connect()
{
    console.log('func socket_connect');
    socket = io.connect('http://url/to/the/app');
}

function socket_reconnect()
{
    console.log('func socket_reconnect');
    socket_connect();
}

function socket_disconnect ()
{
    console.log('func socket_disconnect');
    if (socket) socket.disconnect();
}

On client start up the socket_connect() function works fine, but after using socket.disconnect() , no new connection starts.

Answer 1

You can reconnect by following client side config.

 // for socket.io version 1.0
io.connect(SERVER_IP,{'forceNew':true });

Answer 2

It works now, with socket.socket.reconnect()

function socket_connect()
{
    console.log('func socket_connect');
    socket = io.connect('http://url/to/the/app');
}

function socket_reconnect()
{
    console.log('func socket_reconnect');
    socket.socket.reconnect();
}

function socket_disconnect ()
{
    console.log('func socket_disconnect');
    if (socket) socket.disconnect();
}

If you're using Socket.io 1.0, try using the io manager on the socket to handle manual disconnection and reconnection.

// Connect to socket.io 
var socket = io.connect('url');

function manual_disconnect() {
   socket.io.disconnect();
}

function manual_reconnect() {
   socket.io.reconnect();
}

The reconnecting_attempt, reconnecting, reconnected and connected events on the socket should all be emitted afterwards.
