Question

io.disable('heartbeats');

不幸的是，虽然这似乎阻止了发送的听觉声音，但是当他们没有发送听力时，客户端仍会断开连接。

以下内容不起作用：

io.set('heartbeats', false);

我尝试将一些间隔设置为0，但没有成功：

io.set('heartbeat timeout', 0);
io.set('heartbeat interval', 0);

有关可能正确禁用心跳的建议吗？

Answer 1

代码是

io.disable('heartbeats');

在socket.io v0.8.7上成功测试

不禁用

debug - emitting heartbeat for client 299833185260419425
debug - websocket writing 2::
debug - set heartbeat timeout for client 299833185260419425
debug - got heartbeat packet
debug - cleared heartbeat timeout for client 299833185260419425
debug - set heartbeat interval for client 299833185260419425

禁用

debug - 客户授权

info  - handshake authorized 1205975980561506547
debug - setting request GET /socket.io/1/websocket/1205975980561506547
debug - client authorized for 
debug - websocket writing 1::
debug - websocket writing 5:::{"name":"news","args":[{"hello":"foo"}]}

Answer 2

心跳有问题。我有最新的socket.io和节点0.6.X

   info  - socket.io started
   debug - client authorized
   info  - handshake authorized 734447051478827620
   debug - setting request GET /socket.io/1/websocket/734447051478827620
   debug - client authorized for
   debug - websocket writing 1::
   debug - websocket writing 5:::{"name":"hello"}
   info  - transport end (socket end)
   debug - set close timeout for client 734447051478827620
   debug - cleared close timeout for client 734447051478827620
   debug - discarding transport

// server code
var io = require('socket.io').listen(8080);
io.disable('heartbeats');

io.sockets.on('connection', function (socket) {
  socket.emit('hello');
});

连接后客户端断开连接。

Answer 3

设置socket.io的日志级别，日志级别为2，我们不会看到每个套接字的所有心跳但只看到握手和断开连接

io.set（＆＃39; log level＆＃39;，2）;

禁用Socket.io心跳（Node.js）
