服务器在WebSocket中重新启动时重新连接客户端 [英] Reconnection of Client when server reboots in WebSocket

问题描述

我正在使用通过PHP5和Chrome浏览器作为客户端的网络套接字. 我已从网站 http://code.google.com/p/phpwebsocket/.

I am using web socket using PHP5 and the Chrome browser as client. I have taken the code from the site http://code.google.com/p/phpwebsocket/.

我运行服务器，并且客户端也已连接.我也可以聊天. 现在，当我重新启动服务器(通过杀死它并重新启动它)时， 客户端获得断开连接的信息，但在发送消息时自动不与服务器重新连接.

I run the server, and the client is also connected. I can chat as well. Now when I restart the server (by killing it and starting it again), the client gets the disconnected information, but automatically doesn't reconnect with server when I send the message.

如何实现这一目标?就像我收到断开连接的信息时一样，是否应该检查它并将其发送给JavaScript以刷新页面或重新连接?

How to achieve this? Like when I get the dis-connected information, should I check it and send it to JavaScript to refresh the page or reconnect?

推荐答案

服务器重新启动时，Web套接字连接已关闭，因此触发了JavaScript onclose事件.这是一个示例，尝试每五秒钟重新连接一次.

When the server reboots, the Web Socket connection is closed, so the JavaScript onclose event is triggered. Here's an example that tries to reconnect every five seconds.

function start(websocketServerLocation){
    ws = new WebSocket(websocketServerLocation);
    ws.onmessage = function(evt) { alert('message received'); };
    ws.onclose = function(){
        // Try to reconnect in 5 seconds
        setTimeout(function(){start(websocketServerLocation)}, 5000);
    };
}
