使用方法如下：

mem_zip_file = MemoryZipFile()

mem_zip_file.append_content('mimetype', "application/epub+zip")

mem_zip_file.append_content('META-INF/container.xml', '''<?xml version="1.0" encoding="UTF-8" ?>

''');

#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, 'zip')

to everyone: 2013,Happy New Year!!!!!
