tornado 增加日誌模塊

log類

#!/usr/bin/env python
# -*-  coding:utf-8 -*-
 
import logging.handlers
 
class Logger(logging.Logger):
    def __init__(self, filename=None):
        super(Logger, self).__init__(self)
        # 日誌文件名
        if filename is None:
            filename = 'cgss.log'
        self.filename = filename
 
        # 創建一個handler，用於寫入日誌文件 (每天生成1個，保留30天的日誌)
        fh = logging.handlers.TimedRotatingFileHandler(self.filename, 'D', 1, 5)
        fh.suffix = "%Y%m%d-%H%M.log"
        fh.setLevel(logging.DEBUG)
 
        # 再創建一個handler，用於輸出到控制檯
        ch = logging.StreamHandler()
        ch.setLevel(logging.DEBUG)
 
        # 定義handler的輸出格式
        formatter = logging.Formatter('[%(asctime)s] - %(filename)s [Line:%(lineno)d] - [%(levelname)s]-[thread:%(thread)s]-[process:%(process)s] - %(message)s')
        fh.setFormatter(formatter)
        #ch.setFormatter(formatter)
 
        # 給logger添加handler
        self.addHandler(fh)
        #self.addHandler(ch)

handler類

class test(tornado.web.RequestHandler):
    def get(self):
        log = Logger()
 
        # 輸出日誌
        log.info("日誌模塊消息!")
        log.debug("日誌模塊調試消息!")
        log.error("日誌模塊錯誤消息!")
 
        self.write("hello world")
