mem_zip_file = MemoryZipFile()
mem_zip_file.append_content('mimetype', "application/epub+zip")
mem_zip_file.append_content('META-INF/container.xml', '''
''');

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')
