如何获取参数值

Question

How can I get the value of my parameter to the socket.io server?

In my client I have this simple code:

var id = '0001';
var userame = 'Shane';

socket.on('news', function (data) {
    console.log(data);
    socket.emit('getdetails', {id:id},{username:username});
});

In the server (app.js):

io.on('connection', function (socket) {
    socket.emit('news', { hello: 'world' });
    socket.on('getdetails', function (data) {
        console.log(data.username);
    });
});

But username is undefined. How to get the value of my username?

Answer 1

I think you need to add user name and id to the data param in the client. It looks like when server gets it, data is empty.

Try {id:id,username:username}
