Python gzip库函数使用方法及实例

解压gzip文件示例:
import gzip
f = gzip.open('file.txt.gz', 'rb')
file_content = f.read()
f.close()


创建gzip文件:
import gzip
content = "Lots of content here"
f = gzip.open('file.txt.gz', 'wb')
f.write(content)
f.close()


gzip压缩现有文件:
import gzip
f_in = open('file.txt', 'rb')
f_out = gzip.open('file.txt.gz', 'wb')
f_out.writelines(f_in)
f_out.close()
f_in.close()
 
  
实例：
 
  
从/opt/mat/*.gz文件中读取每一行，找到包含'GET~#~ ~#~'或者'POST~#~ ~#~'的输出该行
 
  
 
  
#!/usr/bin/python
#!encoding:utf8

import shutil
import os
import sys
import glob
import re
import gzip

#扫描目录文件
def parseFile(filename):
    #打开文件，遍历其中的每一行遇到有'GET~#~ ~#~'或者'POST~#~ ~#~'的输出该行
    file = gzip.open(filename, 'rb')
    #eachline = file.readlines()
    for eachline in file:
        #str = eachline
        #if eachline == "*GET~#~ ~#~*" or eachline == "*POST~#~ ~#~*":
        if eachline.find("GET~#~ ~#~") or eachline.find("*POST~#~ ~#~*"):
            print(eachline)
    file.close()
if __name__ == '__main__':
    scandir = '/opt/mat/'
    fileform = '*.gz'
    flist = glob.glob(os.path.join(scandir, fileform))
    for item in flist:
        print(item)
        parseFile(item)
