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', '''<?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')
