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 zipfileImport StringIO Class InMemoryZip (object ):Def _ init _ (self ):# Create the in-memory file-like objectSelf. in_memory_zip = StringIO. StringIO () Def append (self, filename_in_zip, file_contents ):'''Appends a file with name filename_in_zip and contentsFile_contents to th

Copy Code code as follows: Import ZipFile Import Stringio Class Inmemoryzip (object):def __init__ (self):# Create the In-memory File-like objectSelf.in_memory_zip = Stringio.stringio () def append (self, filename_in_zip, file_contents):' Appends a file with name Filename_in_zip and contents ofFile_contents to the in-memory zip. '# Get a handle to the ' in-memory zip in append modeZF = ZipFile.

The code is as follows: Import ZipFileImport Stringio Class Inmemoryzip (object):def __init__ (self):# Create the In-memory File-like objectSelf.in_memory_zip = Stringio.stringio () def append (self, filename_in_zip, file_contents):"Appends a file with name Filename_in_zip and contents ofFile_contents to the in-memory zip.

Use the Java.util.zip.ZipFile class to extract the files. Can extract Zip,jar,war, but cannot extract RAR file.

Take FileInputStream as the representative, writ's reading, is not more than 255, big is to make negative, this I also really can't push out, oh, right, pay attention to different encoding format, such as a Chinese character, read up the number of bytes may be 2, may be 3 bytes. Read reads a bit, the bits that are read are displayed in decimal, and can be converted to characters for easy viewing. 16-bit stream eight-bit streams, outputstreamwriter, base class like Filewrit, these are n

When doing a file operation, the general steps are as follows: Read operation: To target file new an input stream-> read data-> manipulate data Write: New to target file a output stream-> call write method write data Understanding the Java

To operate on a ZIP file, the following three classes are used primarily:1, ZipFile. Represents a class associated with a zip file operation. You can use this class to create a zip file or to open a zip file.2, Ziparchive. Represents a Zip document instance through which you can create a zip document directly from a Stream object. The ZipFile class operates primarily on disk files, while ziparchive represen
