在没有服务器交互的情况下发送客户端到客户端消息

[英]sending client to client messages without server interaction

原文 2013-12-22 15:36:29 4 1 php/ web-services/ webserver

I am not sure if I can explain this correctly…. 我不确定是否可以正确解释...。 But is there a way to send a message from one client to another without bringing the server into interaction…. 但是有没有一种方法可以将消息从一个客户端发送到另一个客户端，而无需使服务器交互……。 I mean the server will setup the channel between two clients and the clients will communicate using that channel only…. 我的意思是服务器将在两个客户端之间建立通道，而客户端将仅使用该通道进行通信…。 No server interaction what so ever… much of what like pubnub does… so basically what I am trying to do is build something like pubnub … I know it is possible… if I'm not mistaken that is….. So, what are the things I need to get started… oh and I'm not sure what tag to put this question in... basically i want something like the following picture... 从来没有服务器交互过……像pubnub所做的很多事情……所以基本上我想做的就是构建像pubnub这样的东西……我知道这是有可能的……如果我没记错的话……..那么，什么是我需要开始的事情...哦，我不确定将这个问题放入哪个标签...基本上，我想要类似下图的内容...
