示例1: _read
# 需要導入模塊: from storages.compat import BytesIO [as 別名]
# 或者: from storages.compat.BytesIO import seek [as 別名]
def _read(self, name):
memory_file = BytesIO()
try:
pwd = self._connection.pwd()
self._connection.cwd(os.path.dirname(name))
self._connection.retrbinary('RETR ' + os.path.basename(name),
memory_file.write)
self._connection.cwd(pwd)
memory_file.seek(0)
return memory_file

raise FTPStorageException('Error reading file %s' % name)示例2: _compress_content
# 需要導入模塊: from storages.compat import BytesIO [as 別名]
# 或者: from storages.compat.BytesIO import seek [as 別名]

# Boto 2 returned the InMemoryUploadedFile with the file pointer replaced,
# but Boto 3 seems to have issues with that. No need for fp.name in Boto3
# so just returning the BytesIO directly

# 需要導入模塊: from storages.compat import BytesIO [as 別名]
# 或者: from storages.compat.BytesIO import seek [as 別名]

# The GZIP header has a modification time attribute (see http://www.zlib.org/rfc-gzip.html)
# This means each time a file is compressed it changes even if the other contents don't change
# For S3 this defeats detection of changes using MD5 sums on gzipped files
# Fixing the mtime at 0.0 at compression time avoids this problem
