Worker::runAll();When the client The callback function triggered when a connection is established with Workerman (after the TCP three-way handshake is completed). The onConnect callback will only be triggered once per connection.
The callback function triggered when the client connection is disconnected from Workerman. No matter how the connection is disconnected, onClose will be triggered as soon as it is disconnected. onClose will only be triggered once per connection.
