Node.js和Socket.IO-如何在断开连接后立即重新连接

编辑：Socket.io已内置支持现在

当我使用socket.io时，断开连接没有发生（仅当我手动关闭服务器时）。但是您可以在例如失败10秒或发生断开事件后说几秒钟后重新连接。

socket.on('disconnect', function(){   // reconnect});

我想出了以下实现：

客户端Javascript

var connected = false;const RETRY_INTERVAL = 10000;var timeout;socket.on('connect', function() {  connected = true;  clearTimeout(timeout);  socket.send({'subscribe': 'schaftenaar'});  content.html("<b>Connected to server.</b>");});socket.on('disconnect', function() {  connected = false;  console.log('disconnected');  content.html("<b>Disconnected! Trying to automatically to reconnect in " +  RETRY_INTERVAL/1000 + " seconds.</b>");  retryConnectOnFailure(RETRY_INTERVAL);});var retryConnectOnFailure = function(retryInMilliseconds) {    setTimeout(function() {      if (!connected) {        $.get('/ping', function(data) {          connected = true;          window.location.href = unescape(window.location.pathname);        });        retryConnectOnFailure(retryInMilliseconds);      }    }, retryInMilliseconds);  }// start connectionsocket.connect();retryConnectOnFailure(RETRY_INTERVAL);

服务器端（node.js）：

// express route to ping server.app.get('/ping', function(req, res) {    res.send('pong');});
