Python uses a memory zipfile object to package files in the memory. Example

This article mainly introduces the example of using the memory zipfile object to package files in the memory in python. For more information, see the following code:

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
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 that
# 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 ")
