前几天稍微看了一下Ratchet,并且实践了一下它官方例子.所以现在就将实践的过程记录下来. 在具体实践之前先将Ratchet是什么东东,要先说明一下.以下的英文是从官方copy过来的 Ratchet is a loosely coupled PHP library providing developers with tools to create real time, bi-directional applications between clients and servers over We…
Why SignalR does not use WebSockets? As you probably know SignalR supports multiple transports. The favor one and most powerful one is of course WEBSOCKET transport. Unfortunately this transport cannot be always used in any infrastructure. When you…
