Question

我使用几乎完全相同的代码分别使用boto将文件上传到Amazon S3和Google Cloud Storage：

import boto

filename = 'abc.png'
filenameWithPath = os.path.dirname(os.path.realpath(__file__)) + '/' + filename
cloudFilename = 'uploads/' + filename

# Upload to Amazon S3
conn = boto.connect_s3(aws_access_key_id=AWS_ACCESS_KEY, aws_secret_access_key=AWS_SECRET_KEY)
bucket = conn.get_bucket(AWS_BUCKET_NAME)
fpic = boto.s3.key.Key(bucket)
fpic.key = cloudFilename
fpic.set_contents_from_filename(filenameWithPath)

# Upload to Google Cloud Storage
conn = boto.connect_gs(gs_access_key_id=GS_ACCESS_KEY, gs_secret_access_key=GS_SECRET_KEY)
bucket = conn.get_bucket(GS_BUCKET_NAME)
fpic = boto.s3.key.Key(bucket)
fpic.key = cloudFilename
fpic.set_contents_from_filename(filenameWithPath)

Amazon S3部分代码运行完美。但是，Google云端存储部分会在语句TypeError, 'str' does not support the buffer interface上提供错误消息fpic.set_contents_from_filename(...)。

问题是什么？

Exception Type: TypeError at /upload/

Boto：上传到Amazon S3 OK，但上传到Google Cloud Storage：'str'不支持缓冲区界面
