复制代码 代码如下:
import zipfile
import StringIO

# Create the in-memory file-like object
self.in_memory_zip = StringIO.StringIO()
def append(self, filename_in_zip, file_contents):

file_contents to the in-memory zip.'''
# Get a handle to the in-memory zip in append mode

# Write the file to the in-memory zip
zf.writestr(filename_in_zip, file_contents)
# Mark the files as having been created on Windows so that
# Unix permissions are not inferred as 0000
for zfile in zf.filelist:
zfile.create_system = 0
return self

'''Returns a string with the contents of the in-memory zip.'''
self.in_memory_zip.seek(0)
