WebSocket++是通过提供各种「Handler」(callback function),来做事件的处理;在官方网站上,有列出可以使用的handler列表(页面)。 而在这个范例里,则是通过set_message_handler(),来设置当Server收到信息时,要执行的callback function,这里就是on_message()这个函数;这也是一般来说,一定会用到的callback function 。
m_server.set_close_handler(bind(&broadcast_server::on_close,this,::_1)); m_server.set_message_handler(bind(&broadcast_server::on_message,this,::_1,::_2)); }voidrun(uint16_t port) {//listen on specified portm_server.listen(port);//Start the server accept loopm_server.start_accep...

With your example I get first message ("some data") after 10 seconds, then after 10 seconds I get three messages from on_interrupt() and then each 10 seconds I get additional two from on_interrupt(). Single message is never sent. What could be the cause?
}//接收到消息的回调方法websocket.onmessage =function (event) { setMessageInnerHTML(event.data); }//连接关闭的回调方法websocket.onclose =function () { setMessageInnerHTML("WebSocket连接关闭"); }//监听窗口关闭事件,当窗口关闭时,主动去关闭websocket连接,防止连接还没断开就关闭窗口,server端会抛异常。
