PYTHON如何在内存中生成ZIP文件

来源：意榕旅游网

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('META-INF/container.xml', '''
 ''');
 #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')
