该食谱提供了一个很好的功能来完成您要问的事情。我已将其修改为使用MD5哈希而不是SHA1，正如您的原始问题所要求的那样
def GetHashofDirs(directory, verbose=0):
import hashlib, os
SHAhash = hashlib.md5()
if not os.path.exists (directory):
return -1
try:
for root, dirs, files in os.walk(directory):
for names in files:
if verbose == 1:
print 'Hashing', names
filepath = os.path.join(root,names)
try:
f1 = open(filepath, 'rb')
except:
# You can't open the file for some reason
f1.close()
continue
while 1:
# Read file in as little chunks
buf = f1.read(4096)
if not buf : break
SHAhash.update(hashlib.md5(buf).hexdigest())
f1.close()
except:
import traceback
# Print the stack traceback
traceback.print_exc()
return -2
return SHAhash.hexdigest()
您可以像这样使用它：
print GetHashofDirs('folder_to_hash', 1)
