通過websocket在定時器上發送消息

我已經設置了服務器，現在我只想每60秒發送一條消息。如何在其他功能中發送消息？我想寫一些像函數gameLoop（）{someobject.send（myMessage）; }但如果是這種情況，那麼someobject.send（myMessage）會是什麼？通過websocket在定時器上發送消息

var server = http.createServer(function(request, response) { 
    console.log((new Date()) + ' Received request for ' + request.url); 
    response.writeHead(404); 
    response.end(); 
}); 
server.listen(3001, function() { 
    console.log((new Date()) + ' Server is listening on port 3001'); 
}); 

wsServer = new WebSocketServer({ 
    httpServer: server, 
    // You should not use autoAcceptConnections for production applications 
    autoAcceptConnections: false 
}); 

function originIsAllowed(origin) { 
    // put logic here to detect whether the specified origin is allowed. 
    return true; 
} 

wsServer.on('request', function(request) { 
    if (!originIsAllowed(request.origin)) { 
    request.reject(); 
    console.log((new Date()) + ' Connection from origin ' + request.origin + ' rejected.'); 
    return; 
    } 

    var connection = request.accept('echo-protocol', request.origin); 
    console.log((new Date()) + ' Connection accepted.'); 
    connection.on('message', function(message) { 
    if (message.type === 'utf8') { 
     console.log('Received Message: ' + message.utf8Data); 
     if(message.utf8Data == "Map?") { 
     connection.send(JSON.stringify(map)); 
     } 
    } 
    }); 
    connection.on('close', function(reasonCode, description) { 
    console.log((new Date()) + ' Peer ' + connection.remoteAddress + ' disconnected.'); 
    }); 
});

要發送，你必須使用消息： wsServer.sendMessage(people, data, id)。因此，您需要在您的gameloop（）函數中使用wsServer對象。作爲替代方法，您可以將node.js中的wsServer設置爲全局對象，如下所示：global.wsServer = wsServer。並訪問它作爲global.wsServer.sendMessage("one", "Game Over", id)

我的IDE是說global.wsServer.sendMessage（）是一個未解決的函數或方法。 –

是否在創建'var wsServer = new WebSocketServer（{...}）後設置了'global.wsServer = wsServer'' – Nivesh

將代碼添加到代碼後，我現在得到：TypeError：undefined不是函數.send（）函數。我正在使用websocket v1.0.22包。 –
