我如何处理 Socket.io 中的关闭事件? [英] How can i handle Close event in Socket.io?

问题描述

我正在制作基于 Web 的简单在线游戏.游戏使用 Socket.io 互相联网.但我遇到了问题.

I'm making simple online game which based on Web. the game uses Socket.io for netwoking each other. but I encountered the problem.

考虑以下情况.我运行了 Socket.io 服务器.一名玩家制作房间，另一名玩家加入房间.他们玩了一段时间游戏..但是一位玩家非常生气并关闭了游戏标签.

think about following situation . I ran Socket.io server. one player making the room , and other player join the room. they played game some time .. but one player so angry and close the game tab.

在这种情况下，如何在服务器端获取一个客户端关闭浏览器的事件?

in this situation , how can I get the event which one client have been closed the browser in server-side ?

根据谷歌搜索，人们这样说:使用浏览器关闭事件，如 onBeforeUnload"

according to googling , peoples say like this : "use browser-close event like onBeforeUnload"

但我知道所有浏览器都不支持 onBeforeUnload 事件.所以我想要解决方案在 SERVER SIDE 检查客户端断开连接事件.

but I know that All browser don't support onBeforeUnload event. so i want solution about checking the client disconnection event in SERVER SIDE.

在 Socket.io ( nodeJS ) 服务器端控制台，当客户端的连接关闭时，控制台显示如下:

in Socket.io ( nodeJS ) server-side console , when client's connection closed , the console say like following :

调试 - 丢弃传输

我的 nodeJS 版本是 0.4.10，Socket.io 版本是 0.8.7.并且两者都在 Linux 上运行.

My nodeJS version is 0.4.10 and Socket.io version is 0.8.7. and both are running on Linux.

有人可以帮忙吗?

短代码在这里:

var io = require ( "socket.io" ).listen ( 3335 );
io.sockets.on ( "connection" , function ( socket )
{
  socket.on ( "req_create_room" , function ( roomId ) 
  {
    var socketInstance = io
    .of ( "/" + roomId )
    .on ( "connection" , function ( sock )
    {
       sock.on ( "disconnect" , function () 
       {
          // i want this socket data always displayed...
          // but first-connected-client doesn't fire this event ..
          console.log ( sock );
       }
    });
  });
});

推荐答案

更新: 我创建了 一篇博文 用于此解决方案.欢迎任何反馈！

Update: I created a blog post for this solution. Any feedback is welcome!

我建议对 Socket IO 使用卸载时同步断开连接"选项.我遇到了类似的问题，这真的帮了我.

I recommend using the 'sync disconnect on unload' option for Socket IO. I was having similar problems, and this really helped me out.

在客户端:

var socket = io.connect(<your_url>, {
'sync disconnect on unload': true });

无需连接任何unload 或beforeunload 事件.在多个浏览器中尝试了这一点，到目前为止效果很好.

No need to wire in any unload or beforeunload events. Tried this out in several browsers, and its worked perfectly so far.
