ofs 0.4.3

要求

对于所有基于boto的存储（Google Storage，S3等）需要boto>=2.0。

示例用法

(本地版本 - 依赖于‘pairtree’，以及‘simplejson’)

 >>> from ofs.local import PTOFS

 >>> o = PTOFS()
 (Equivalent to 'o = PTOFS(storage_dir = "data", uri_base="urn:uuid:", hashing_type="md5")')

 # Claim a bucket - this will add the bucket to the list of existing ones
 >>> uuid_id = o.claim_bucket()
 >>> uuid_id
 '4aaa43cdf5ba44e2ad25acdbd1cf2f70'

 # Choose a bucket name - if it exists, a new UUID one will be formed instead and returned
 >>> bucket_id = o.claim_bucket("foo")
 >>> bucket_id
 'foo'
 >>> bucket_id = o.claim_bucket("foo")
 >>> bucket_id
 '1bf93208521545879e79c13614cd12f0'

 # Store a file:
 >>> o.put_stream(bucket_id, "foo.txt", open("foo....))
 {'_label': 'foo.txt', '_content_length': 10, '_checksum': 'md5:10feda25f8da2e2ebfbe646eea351224', '_last_modified': '2010-08-02T11:37:21', '_creation_date': '2010-08-02T11:37:21'}

 # or:
 >>> o.put_stream(bucket_id, "foo.txt", "asidaisdiasjdiajsidjasidji")
 {'_label': 'foo.txt', '_content_length': 10, '_checksum': 'md5:10feda25f8da2e2ebfbe646eea351224', '_last_modified': '2010-08-02T11:37:21', '_creation_date': '2010-08-02T11:37:21'}

 # adding a file with some parameters:
 >>> o.put_stream(bucket_id, "foooo", "asidaisdiasjdiajsidjasidji", params={"original_uri":"http://...."})
 {'_label': 'foooo', 'original_uri': 'http://....', '_last_modified': '2010-08-02T11:39:11', '_checksum': 'md5:3d690d7e0f4479c5a7038b8a4572d0fe', '_creation_date': '2010-08-02T11:39:11', '_content_length': 26}

 # Get the underlying URL pointing to a resource
 >>> o.get_url(bucket_id, "foo")
   [typical local pairtree response:]
"file:///opt/ofs_store/pairtree_root/1b/f9/32/......./obj/foo"
   [typical remote response]
"http://..."
"ftp://..."

 # adding to existing metadata:
 >>> o.update_metadata(bucket_id, "foooo", {'foo':'bar'})
 {'_label': 'foooo', 'original_uri': 'http://....', '_last_modified': '2010-08-02T11:39:11', '_checksum': 'md5:3d690d7e0f4479c5a7038b8a4572d0fe', '_creation_date': '2010-08-02T11:39:11', '_content_length': 26, 'foo': 'bar'}

 # Remove keys
 >>> o.remove_metadata_keys(bucket_id, "foooo", ['foo'])
 {'_label': 'foooo', 'original_uri': 'http://....', '_last_modified': '2010-08-02T11:39:11', '_checksum': 'md5:3d690d7e0f4479c5a7038b8a4572d0fe', '_creation_date': '2010-08-02T11:39:11', '_content_length': 26}

 # Delete blob
 >>> o.exists(bucket_id, "foooo")
 True
 >>> o.del_stream(bucket_id, "foooo")
 >>> o.exists(bucket_id, "foooo")
 False

 # Iterate through ids for buckets held:
 >>> for item in o.list_buckets():
 ...   print(item)
 ...

 4a726b0a33974480a2a26d34fa0d494d
 4aaa43cdf5ba44e2ad25acdbd1cf2f70
 .... etc

 # Display the labels in a specific bucket:
 >>>o.list_labels("1bf93208521545879e79c13614cd12f0")
 [u'foo.txt']

开发者

测试使用plain unittest但建议使用nose。

要运行botostore测试，您需要将test.ini.tmpl复制到test.ini，并填写Google存储账户的详细信息。
