Question

我已经设置了服务器，现在我只想每隔60秒发送一条消息。如何在其他功能中发送消息？我想编写类似函数gameLoop（）{someobject.send（myMessage）;但是如果是这样的话，那么someobject.send（myMessage）会是什么？

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.');
  });
});

要发送消息，您必须使用： wsServer.sendMessage(people, data, id)。因此，在gameloop（）函数中需要wsServer个对象。作为替代方案，您可以将node.js中的wsServer设置为全局对象：global.wsServer = wsServer。并将其作为global.wsServer.sendMessage("one", "Game Over", id)
