Add support for creating a ResumableUpload object with a resumable_url.

[aviau]

Hello,

Does this library support resuming an upload?

More specificly, can I construct a working ResumableUpload object from a resumable_url ?

If yes, is there an example of this anywhere?

I'm also looking for this.

I thought the purpose is to be able to reinitiate an upload from the initial resumable_url so we can continue uploading the next chunks without having to start over.

Is there any good example for this?

There isn't currently support for re-creating the ResumableUpload object from a resumable_url.
The intent is that you would keep the ResumableUpload object around and continue to upload chunks from it.

This is the sample that shows how to do resumable uploads:

https://googleapis.github.io/google-resumable-media-python/latest/google.resumable_media.requests.html#resumable-uploads

Oh... right. So I guess our case is beyond the scope of the application. Where we might have lost internet connection or had to even restart the entire server and thought we can resume the upload.

I found something close to what I'm looking for here if anyone is looking: https://medium.com/google-cloud/google-cloud-storage-signedurl-resumable-upload-with-curl-74f99e41f0a2

Looking at the library and product documentation on resumable uploads, I think it would be possible to add this as a new feature.

Documentation on resuming uploads with the resumable session uri:

• https://developers.google.com/drive/api/v3/manage-uploads#resume-upload
• https://cloud.google.com/storage/docs/json_api/v1/how-tos/resumable-upload#resume-upload

Summary:

• Create an empty PUT request to the resumable session URI with a Content-Range header indicating that current position is unknown
• Send the request
• Process the request. If a 308 Resume Incomplete is received, process the response's Range and continue uploading from that location.

@busunkim96 thanks for that! I tried the restful APIs and it works well!
