使用python实现日志功能

Python脚本日志系统

 

  Python通过logging模块提供日志功能,关于logging模块的使用网络上已经有很多详细的资料,这里要分享的是怎样在实际工程中使用日志功能。

  假设要开发一个自动化脚本工具,工程结构如下,Common这个package是框架功能的实现,Scripts目录是我们编写的测试用例脚本(请忽略其他不相关的目录)。

  我们对日志功能的需求如下:

  1 为了便于日志的查看,每个脚本对应一个日志文件,日志文件以脚本的名字命名

  2 日志路径以及每个脚本保存的日志容量可以设置,比如设置为5MB,则超过后最老日志被自动覆盖

  3 日志功能要使用方便,减少与框架业务功能的耦合

  现在来逐一分析上述需求。

  1 要实现每个脚本一个日志文件,则需要在日志模块中,根据用例脚本的名字来生成日志文件,这里的关键问题就是怎样在日志模块中获取用例脚本的名字。

  获取文件名的常用方法有:os.getcwd(), sys.argv[0], __file__,来看下各种的作用:

  先在一个文件(假设为test.py)中编写如下代码:

  可见,os.getcwd()获取的是执行脚本的目录, sys.argv[0]是执行脚本的绝对路径名, __file__是被执行代码所在文件的绝对路径名。

  现在就清楚了,我们应该用sys.argv[0]来获取执行脚本的名字,由于获取到的是绝对路径,需要做一点处理:sys.argv[0].split('/')[-1].split('.')[0]

  2 日志容量问题,要实现超过容量后自动覆盖最老日志,采用logging中的RotatingFileHandler类即可,可以设置日志文件的大小,以及备份个数。

  那么日志路径和容量配置放在哪里呢?让用户直接修改RotatingFileHandler的参数显然不好,最好不要让用户修改框架文件,用户只需调用接口写自己的脚本即可。

  这里采用的方案是将配置信息写入一个文件,XML文件比较适合用来作为配置文件,用户通过修改XML文件来制定配置,日志模块从XML文件读取参数。

  这里为了方便将XML文件放入Common下面,命名为config.xml,内容为:

使用python实现日志功能
<?xml version="1.0" encoding="utf-8"?>

<config>
<!-- 日志保存路径 -->
<logpath>E:\PythonLog</logpath> <!-- 每个脚本对应的日志文件大小,单位MB -->
<logsize>8</logsize> <!-- 每个脚本保存的日志文件个数 -->
<lognum>3</lognum>
</config>
使用python实现日志功能

  读取XML文件内容,使用lxml库非常简单,后面再给出代码。

  

  3 日志功能要使用方便,减少与框架业务功能的耦合,最好就是对日志功能进行封装,只提供记录日志的接口即可。

  日志接口采用类方法的形式就可以满足上述要求,用户只需要通过类调用日志记录接口,随处调用,使用方便,并且无需定义类实例,与框架业务没有耦合。

    

  有了上述分析,我们来实现日志模块。

  由于日志功能也是框架基础的一部分,我们将日志模块也放在Common这个package中,在Common下新建log.py文件,代码如下:

使用python实现日志功能
 1 # coding: utf-8
2
3 from lxml import etree 或者from lxml import html
4 import logging.handlers
5 import logging
6 import os
7 import sys
8
9 # 提供日志功能
10 class logger:
11 # 先读取XML文件中的配置数据
12 # 由于config.xml放置在与当前文件相同的目录下,因此通过 __file__ 来获取XML文件的目录,然后再拼接成绝对路径
13 # 这里利用了lxml库来解析XML
14 root = etree.parse(os.path.join(os.path.dirname(__file__), 'config.xml')).getroot()
15 # 读取日志文件保存路径
16 logpath = root.find('logpath').text
17 # 读取日志文件容量,转换为字节
18 logsize = 1024*1024*int(root.find('logsize').text)
19 # 读取日志文件保存个数
20 lognum = int(root.find('lognum').text)
21
22 # 日志文件名:由用例脚本的名称,结合日志保存路径,得到日志文件的绝对路径
23 logname = os.path.join(logpath, sys.argv[0].split('/')[-1].split('.')[0])
24
25 # 初始化logger
26 log = logging.getLogger()
27 # 日志格式,可以根据需要设置
28 fmt = logging.Formatter('[%(asctime)s][%(filename)s][line:%(lineno)d][%(levelname)s] %(message)s', '%Y-%m-%d %H:%M:%S')
29
30 # 日志输出到文件,这里用到了上面获取的日志名称,大小,保存个数
31 handle1 = logging.handlers.RotatingFileHandler(logname, maxBytes=logsize, backupCount=lognum)
32 handle1.setFormatter(fmt)
33 # 同时输出到屏幕,便于实施观察
34 handle2 = logging.StreamHandler(stream=sys.stdout)
35 handle2.setFormatter(fmt)
36 log.addHandler(handle1)
37 log.addHandler(handle2)
38
39 # 设置日志基本,这里设置为INFO,表示只有INFO级别及以上的会打印
40 log.setLevel(logging.INFO)
41
42 # 日志接口,用户只需调用这里的接口即可,这里只定位了INFO, WARNING, ERROR三个级别的日志,可根据需要定义更多接口
43 @classmethod
44 def info(cls, msg):
45 cls.log.info(msg)
46 return
47
48 @classmethod
49 def warning(cls, msg):
50 cls.log.warning(msg)
51 return
52
53 @classmethod
54 def error(cls, msg):
55 cls.log.error(msg)
56 return
使用python实现日志功能

  来测试一下,在脚本script1和script2中分别编写下面代码:

from Common.log import *

logger.info('This is info')
logger.warning('This is warning')
logger.error('This is error')

  分别运行两个脚本,控制台输出为:
