    var toid = {$toid};

     var ws =  new WebSocket("ws://127.0.0.1:8282");

      ws.onmessage = function(e){

       var message =  eval("(" e.data ")");
          switch (message.type){

   public static function onMessage($client_id, $message)
   {
       $message_data = json_decode($message,true);
       if(!$message_data){

       }
       switch($message_data['type']){
           case "bind":
               $fromid = $message_data['fromid'];
               Gateway::bindUid($client_id, $fromid);
               return;
           case "say":
               $text = nl2br(htmlspecialchars($message_data['data']));
               $fromid = $message_data['fromid'];
               $toid = $message_data['toid'];

               $date=[
                   'type'=>'text',
                   'data'=>$text,
                   'fromid'=>$fromid,
                   'toid'=>$toid,
                   'time'=>time()
               ];

               if(Gateway::isUidOnline($toid)){
                   Gateway::sendToUid($toid, json_encode($date));
                   $date['isread']= 1;
               }else{
                   $date['isread']=0;
               }

               $date['type']="save";
               Gateway::sendToUid($fromid,json_encode($date));

               return;
       }
   }

                  //指定两个聊天对象聊天
                      if(toid==message.fromid) {

                          $(".chat-content").append(' <div class="chat-text section-left flex"> <span class="text"><i class="icon icon-sanjiao4 t-32"></i>'   message.data   '</span> </div>');

                  save_message(message);
                  return;
          }
    }
