网站服务器(Apach)日志读取分析成图及代码

先说一句招黑的话:python是最好的编程语言!
还有王法吗?
没有之一
还有谁

近来一直在学python,
最先知道python可以做爬虫,简单几行代码,轻松爬取网站的内容
上手也比较快,即学即上岗
即学即上岗
python真是无所不能呀,越来越被人重视,现在是引用这张经典照片的时候了
人生苦短,我用python
比如现在使用Arcpy写一写批处理的脚本,解决很多繁琐的问题
还有爬虫,将爬到的数据分析一下,很有成就感
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
过年放假前,接到一项挑战:将公司论坛网站(ArcGIS知乎)服务器上的Apach日志分析一下,看看网站论坛的搜索情况
日志是每天生成一个,一共是二百多天的,总共大概1.3个G,数量不大。

读取数据 每天搜索次数统计

1、首先肯定是看一下这些文件名字,嗯,很正规,方便后续的读取和存储
日志
2、然后随便打开一个文件,分析一下存储结构,
然后找到自己需要的内容,初步思考怎么提取出来
文件
3、接着尝试写代码读取一个文件看看,无压力
4、现在要的是将里面有形如“GET //search/ajax/search_result/search_type-questions__q-%E5%85%A5%E9%97%A8”搜索的请求行取出来,找到其中q-%E5%85%A5%E9%97%A8字符串,
然后使用“urllib.parse.unquote”转码,转为可以读懂的关键词,这就是要的结果了
5、读取到每个日志文件中的关键词后,将其存储到文本中,代码如下,

###读取源数据,通过挑选、反编码并写入内存
rootdir = "C://Users//Esri//Desktop//log"
loglist = []
tongjilist = []
for parent, dirnames, filenames in os.walk(rootdir):
day = 1
i = 1
for filename in filenames:
filedate = filename[7:-4]
filepath = os.path.join(parent, filename)
# print(filedate)
# print(filepath)
input = open(filepath, 'r')
num = 1
for line in input:
if (
'GET //search/ajax/search_result/search_type-questions__q-' and 'template-__page-1' and 'search_type-questions') in line:
kw1 = line.split()[6][53:-19]
kw = urllib.parse.unquote(kw1).replace('_', '')
if '?' in kw:
pass
else:
# file1 = open('C://Users//Esri//Desktop//statistics//原始数据.txt', 'a',encoding='utf-8')
logline = str(line.split()[0]) + ',' + str(line.split()[3][1:]) + ',' + kw + '\n'
loglist.append(logline)
# file1 = file1.write(line1)
# print(i)
i += 1
num += 1
day += 1
print(filedate + ":共有" + str(num) + "次搜索")
# file2 = open('C://Users//Esri//Desktop//statistics//每天搜索次数统计.txt', 'a')
tongjiline = filedate + ',' + str(num) + '\n'
tongjilist.append(tongjiline)
###创建文本并写入数据表头
log = open('C://Users//Esri//Desktop//statistics//原始数据.txt', 'w', encoding='utf-8')
loghead = "IP" + ',' + "日期" + ',' + "搜索关键词" + '\n'
log.write(loghead) # 写文件头
log.close()
tongji = open('C://Users//Esri//Desktop//statistics//每天搜索次数统计.txt', 'w', encoding='utf-8')
tongjihead = "日期" + ',' + "次数" + '\n'
tongji.write(tongjihead) # 写文件头
tongji.close()
###将内存的list保存到文本中
openlog = open('C://Users//Esri//Desktop//statistics//原始数据.txt', 'a', encoding='utf-8')
openlog.writelines(loglist)
openlog.close()
opentongji = open('C://Users//Esri//Desktop//statistics//每天搜索次数统计.txt', 'a', encoding='utf-8')
opentongji.writelines(tongjilist)
opentongji.close()
del loglist
del tongjilist
day -= 1
sumday = i - 1
print(str(day) + "天一共有:" + str(sumday) + "次搜索")
# print(filedate)
startday = (datetime.datetime.strptime(filedate, "%Y-%m-%d") - datetime.timedelta(days=day - 1)).strftime("%Y-%m-%d")
# print(startday)

PS:读取完文件花了10S

同一IP、日期、搜索关键词结果去重

好了,得到初步结果。
通过代码,可以看到:每天搜索次数统计.txt中包含了三方面的内容:IP,时间,搜索关键词,
对于同一IP,同一时间,同一搜索关键词进行去重,得到清洗后的数据源,才能进行后续的有效分析
代码如下

搜索关键词Top100统计

有了数据能做些什么呢?
既然是网站论坛的搜索关键词统计,那么统计一下搜索次数最高的关键词 TOP100!
python很容易上手,那么问题来了:你将对Python的了解不够深入。
所以在你开始实现自己的想法时,一种“朴素的编程思想”贯穿脑中,费尽心力写了几十行,还不怎么完美
最后发现该功能已经写成函数了,你只需用一行去调用即可。
这里不禁感叹python的强大:没有做不到的,只有你想不到的。
好吧,这是我的心得体会!

如果想知道运行这些过程消耗的时间,可以在最后加上以下代码

1
2
3
4
5
'''执行操作时间'''
endtime = datetime.datetime.now()
time = (endtime - starttime).seconds
print('------------------------------------------------------' + '\n' + "一共用时" + str(time) + "秒")
print('邮件发送给:%s'%_to.split(','))

最后的最后,如果你觉得每天的统计次数成图效果不好,可以制作一个HTML网页去展示,调用js的C3库,易于交互查看
