稍微成型点的用WEBSOCKET实现的实时日志LOG输出-白红宇

难的是还是就地用JS显示出来相关的发布进度。

还好，花了一下午实现了。

可以移植到项目中去罗。。。

websocket.py：

import tornado.ioloopimport tornado.webimport tornado.websocketfrom tornado.ioloop import IOLoopfrom datetime import timedeltaimport timeimport osimport sysimport tornado.httpserverclass WebSocketHandler(tornado.websocket.WebSocketHandler):    file_content = ""    filename = "test.log"    def open(self):        pass    def update_client(self):        self.write_message(self._read_file(self.filename))    def on_message(self, message):        print message        self.filename = message.split('-')[1]        self.update_client()    def on_close(self):        pass    def _read_file(self, filename):        print filename, '================='        with open(filename) as f:            content = f.read()            content_diff = content.replace(self.file_content, '')            self.file_content = content            return content_diffclass IndexPageHandler(tornado.web.RequestHandler):    def get(self):        self.render("websockets.html")class Application(tornado.web.Application):    def __init__(self):        handlers = [            (r'/', IndexPageHandler),            (r'/ws', WebSocketHandler)        ]        settings = dict(            template_path=os.path.join(os.path.dirname(__file__), "templates"),            static_path=os.path.join(os.path.dirname(__file__), "static"),            debug=True        )        tornado.web.Application.__init__(self, handlers, **settings)if __name__ == '__main__':    ws_app = Application()    server = tornado.httpserver.HTTPServer(ws_app)    server.listen(8888)    tornado.ioloop.IOLoop.instance().start()
