python在内存中生成Zip文件！
import zipfile
import StringIO
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('META-INF/container.xml', '''<?xml version="1.0" encoding="UTF-8" ?>
<container version="1.0" xmlns="urn:oasis:names:tc:opendocument:xmlns:container"> </container>''');
#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!!!!!
