javascript - I'm trying to return socket id?

Question

I'm trying to use express.io module for the first time and I like it. It's really extended part of socket.io and express.js.

I'm trying to return socket.id in app.io.route event. How can I get client unique id using express.io?

app.io.route('debug', function(socket) {
    console.log( socket.id );
});

Answer 1

该route函数接收一个SocketRequest对象，因此您需要以下内容：

app.io.route('debug', function (req) {
    console.log( req.io.id );
});

如果需要，您也可以直接访问 socket.io 套接字 ( req.socket)，但如果可能，您应该使用上面的 RequestIO 对象。
