我有这个代码用于从我的Arduino接收数据,但我想将数据发送回我的A​​rduino并在我的客户端页面上获得响应.我添加了一个监听功能,但是io.on is not a function当我从客户端页面发送数据时,我一直在收听.

test.js

io.listen(app.listen(3000)).on('connection', function (client) {

    // store client into array
    clients.push(client);

    // on disconnect
    client.on('disconnect', function() {

        // remove client from array
        clients.splice(clients.indexOf(client), 1);


    });

    // I added this to listen for event from my chart.JS

    io.on('connection', function(socket){

        socket.on('LED on', function (data) {
            console.log(data);

        });
        socket.on('LED off', function (data) {
            console.log(data);

        });
    });
});
