网页里使用websocket读取后台日志并实时展示

1. 后台启动websocket(需要 cherrypy & ws4py 支持)

    python websocketlogserver.py
   

2. 网页里加载 websocketlogreader.js

    <script src="websocketlogreader.js"></script>
   
    <script type='text/javascript'>
   
    var websocket = 'ws://192.168.1.198:9001/ws';
    var background_task_pid = 1234;
    var background_task_log = '/var/log/some.log';
    $("#logs").websocketlogreader({
        websocket:websocket
        ,pid:background_task_pid
        ,logfile:background_task_log
        ,onclose:function(evt){
            // background task finished
        }
    });
   
    </script>
