PYTHON이 메모리에 ZIP 파일을 생성하는 방법

如题，代码如下：

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: 写文本内容到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:写文件内容到zip

      注意这里的第二个参数是本地磁盘文件的全路径(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: 读取zip文件内容

      """

      self._memory_zip.seek(0)

      return self._memory_zip.read()

 

  def write_file(self, filename):

      """

      description:写zip文件到磁盘

      """

      f = file(filename, "wb")

      f.write(self.read())

      f.close()

使用方法如下：

        mem_zip_file = MemoryZipFile()
        mem_zip_file.append_content('mimetype', "application/epub+zip")
        mem_zip_file.append_content(&#39;META-INF/container.xml&#39;, &#39;&#39;&#39;<?xml version="1.0" encoding="UTF-8" ?>
<container version="1.0" xmlns="urn:oasis:names:tc:opendocument:xmlns:container"> </container>&#39;&#39;&#39;);
        #追加磁盘上的文件内容到内存，注意这里的第二个参数是本地磁盘文件的全路径(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, &#39;zip&#39;)
