How python generates a zip file in memory

Title, the code is as follows:

Class Memoryzipfile (object):   def __init__ (self):       #创建内存文件       self._memory_zip = Stringio.stringio ()           def append_content (self, Filename_in_zip, file_content): "" "       Description: Write text content to zip" ""       ZF = ZipFile . ZipFile (Self._memory_zip, "a", ZipFile. zip_deflated, False)       zf.writestr (Filename_in_zip, file_content) for       Zfile in Zf.filelist:zfile.create_ System = 0       return self            def append_file (self, Filename_in_zip, Local_file_full_path): "" "       

Description: Write file contents to zip

Note that the second parameter here is the full path to the local disk file (Windows:c/demo/1.jpg | Linux:/usr/local/test/1.jpg)

"""

ZF = ZipFile. ZipFile (Self._memory_zip, "a", ZipFile. zip_deflated, False)

Zf.write (Local_file_full_path, Filename_in_zip)

For zfile in Zf.filelist:zfile.create_system = 0

return self

def read (self):

"""

Description: Reading the contents of a zip file

"""

Self._memory_zip.seek (0)

Return Self._memory_zip.read ()

def write_file (self, filename):

"""

Description: Write zip file to disk

"""

f = file (filename, "WB")

F.write (Self.read ())

F.close ()

Here's how to use it:

        Mem_zip_file = Memoryzipfile ()        mem_zip_file.append_content (' mimetype ', "Application/epub+zip")        Mem_zip_ File.append_content (' Meta-inf/container.xml ', '
 
  
 
   
 
  ");        #追加磁盘上的文件内容到内存, note that the second parameter here is the full path to the local disk file (Windows:c/demo/1.jpg | linux:/usr/local/test/1.jpg)        Mem_zip_file.append _file ("1.jpg", "c:\1.jpg")            #将内存中的zip文件写入磁盘        mem_zip_file.write_file ("C:test.zip")          #获取内存zip文件内容        data = Mem_zip_file.read ()          #上传到fdfs        my_fdfs_client.upload_by_buffer (data, ' zip ')
