python 动态生成 zip 文件

python 中处理 zip 文件

from zipfile import ZipFile

z = ZipFile('abc.zip', 'w')
z.write('abc.txt', 't/abc.txt')
z.writestr('t/abc2.txt', 'this text is from my')
z.close()


# 即时压缩

import os
from zipfile import ZipFile
from StringIO import StringIO

f = StringIO()
z = ZipFile(f, 'w')

def safewrite(f, *arg, **kw):
    if os.path.isfile(f):
        z.write(f, *arg, **kw)
    elif os.path.isdir(f):
        for root, dirs, files in os.walk(f):
            for f_ in files:
                z.write(os.path.join(root, f_))

safewrite('flash')
safewrite('abc.txt', 't/abc.txt')
z.writestr('t/abc2.txt', 'this text is from my')
z.close()


print 'Content-Type: application/zip'
print 'Content-Disposition: attachment; filename=abc.zip'
print

print f.getvalue()
