Python uses memory ZipFile objects to package files in memory sample _python

Copy Code code as follows:

Import ZipFile
Import Stringio

Class Inmemoryzip (object):
def __init__ (self):
# Create the In-memory File-like object
Self.in_memory_zip = Stringio.stringio ()

def append (self, filename_in_zip, file_contents):
' Appends a file with name Filename_in_zip and contents of
File_contents to the in-memory zip. '
# Get a handle to the ' in-memory zip in append mode
ZF = ZipFile. ZipFile (Self.in_memory_zip, "a", ZipFile). zip_deflated, False)

# 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
# Unix permissions are not inferred as 0000
For Zfile in Zf.filelist:
Zfile.create_system = 0

return self

def read (self):
' Returns a string with the contents of the in-memory zip. '
Self.in_memory_zip.seek (0)
Return Self.in_memory_zip.read ()

def writetofile (self, filename):
"' writes the in-memory zip to a file. '
f = file (filename, "w")
F.write (Self.read ())
F.close ()

if __name__ = = "__main__":
# Run a test
Imz = Inmemoryzip ()
Imz.append ("Test.txt", "Another Test"). Append ("Test2.txt", "Still Another")
Imz.writetofile ("Test.zip")
