呵呵,最近在学习python,只明白了大概,很多还不会,不熟悉。现在放一个python程序,目标是:遍历文件夹里的torrent文件,分析hash info 加密后是否跟原文件的文件名相同,不同的话,记录log文件。我写起来有点复杂,感觉还不是按照python的思维来写程序,要学的还很多。
#! /usr/bin/python
from sys import *
from bencode import *
import hashlib
import os
import os.path
#-----test-----
#if len(argv) != 2:
# print "ERROR: use ./33.py filename"
# exit(2)
#file_name = argv[1]
#-----test-----
def check_torrent_hash(file_name):
filename ='torrent/'+file_name
metainfo_file = open(filename, 'rb')
if metainfo_file:
metainfo = bdecode(metainfo_file.read())
else:
print "ERROR: Not a valid torrent file"
exit(1)
metainfo_file.close()
info = metainfo['info']
hahaha = bencode(info)
mySha1 = hashlib.sha1()
mySha1.update(hahaha)
mySha1_Digest = mySha1.hexdigest()
up_str = mySha1_Digest.upper();
OK = file_name.split('.')
#print up_str
#print OK[0]
if not up_str==OK[0]:
error_file = open('/home/changyou/wget/error.log', 'a+')
error_file.writelines(up_str+'\n')
error_file.close()
return 'NO~~please check /home/changyou/wget/error.log'
else:
return 'OK!!!'
rootdir = "/home/changyou/wget/torrent/"
for parent, dirnames, filenames in os.walk(rootdir):
for filename in filenames:
print check_torrent_hash(filename)
