问题描述
我有一个数据库充满BlobKeys，以前通过标准的Google App Engine上传过程，并通过设置 gs_bucket_name 参数将每个上传文件传送到同一Google云端存储分区。
我想要做的是能够解码现有的blobkeys，以便我可以获取他们的Google Cloud Storage文件名。我知道我 可以 使用属性来自并没有做到这一点，因为它取代了谷歌存储文件名并创建了一个blobkey。
那么，我怎样才能把一个以前上传的blobkey Google云存储存储分区通过应用引擎，并获得它的Google云存储文件名？（python）
您可以获取cloudstorage文件名只存在于上传处理程序（fileInfo.gs_object_name）中，并将其存储在数据库中。之后，它将丢失，并且似乎不会保留在BlobIn中fo或其他元数据结构。
更新：我能够解码Blobstore-Viewer中的SDK-BlobKey：encoded_gs_file：base64-encoded-filename-here。然而，真实的东西不是base64编码的。
create_gs_key（文件名，rpc =无）... Google说：以字符串形式返回加密的blob密钥。有没有人猜测为什么这是加密的？
I've got a database full of BlobKeys that were previously uploaded through the standard Google App Engine create_upload_url() process, and each of the uploads went to the same Google Cloud Storage bucket by setting the gs_bucket_name argument.
What I'd like to do is be able to decode the existing blobkeys so I can get their Google Cloud Storage filenames. I understand that I could have been using the gs_object_name property from the FileInfo class, except:
Meaning gs_object_name property is only available in the upload handler, and if I haven't been saving it at that time then its lost.
Also, create_gs_key() doesn't do the trick because it instead takes a google storage filename and creates a blobkey.
So, how can I take a blobkey that was previously uploaded to a Google Cloud Storage bucket through app engine, and get it's Google Cloud Storage filename? (python)
You can get the cloudstorage filename only in the upload handler (fileInfo.gs_object_name) and store it in your database. After that it is lost and it seems not to be preserved in BlobInfo or other metadata structures.

Update: I was able to decode a SDK-BlobKey in Blobstore-Viewer: "encoded_gs_file:base64-encoded-filename-here". However the real thing is not base64 encoded.
create_gs_key(filename, rpc=None) ... Google says: "Returns an encrypted blob key as a string." Does anyone have a guess why this is encrypted?
