tornado 增加日志模块

log类

#!/usr/bin/env python
# -*-  coding:utf-8 -*-
 
import logging.handlers
 
class Logger(logging.Logger):
    def __init__(self, filename=None):
        super(Logger, self).__init__(self)
        # 日志文件名
        if filename is None:
            filename = 'cgss.log'
        self.filename = filename
 
        # 创建一个handler，用于写入日志文件 (每天生成1个，保留30天的日志)
        fh = logging.handlers.TimedRotatingFileHandler(self.filename, 'D', 1, 5)
        fh.suffix = "%Y%m%d-%H%M.log"
        fh.setLevel(logging.DEBUG)
 
        # 再创建一个handler，用于输出到控制台
        ch = logging.StreamHandler()
        ch.setLevel(logging.DEBUG)
 
        # 定义handler的输出格式
        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)
 
        # 给logger添加handler
        self.addHandler(fh)
        #self.addHandler(ch)

handler类

class test(tornado.web.RequestHandler):
    def get(self):
        log = Logger()
 
        # 输出日志
        log.info("日志模块消息!")
        log.debug("日志模块调试消息!")
        log.error("日志模块错误消息!")
 
        self.write("hello world")
