workerman不支持c++的weboscket

a6965921

客户端的cocos2d-x(c++)的websocket

发到你们workerman 可以收到客户端发来的握手请求 但是接下来没反应了 你们貌似把她加密 发给客户端 导致握手失败 没办法成功的连接

以下PHP代码可以握手成功 成功的和客户端连接上

walkor

看样子是没有完成websocket握手。

你可以直接用http://www.workerman.net/workerman-chat这个框架来做,这个是基于websocket的聊天室,里面有websocket类,并且有握手相关代码可以直接复用。

websocket握手和业务逻辑都在 applications/Chat/Event.php 中,里面代码很少,有详细的注释,很好理解。你稍加修改应该就能满足你的需求
