I am trying to upload a file to a private bucket in BB. The code sample here is what I am trying.

Firstly, there are two API endpoint variables in the settings - ENDPOINT (with a given value) and ENDPOINT_URL_YOUR_BUCKET. What is the difference between them? The private bucket I have created shows endpoint variable having value as s3.us-east-005.backblazeb2.com (almost similar to the ENDPOINT value provided in the settings file), is that to be used for both? Otherwise, what is to be filled in each of these two?

Secondly, what are ENDPOINT_URL_YOUR_BUCKET, KEY_ID_YOUR_ACCOUNT and APPLICATION_KEY_YOUR_ACCOUNT, all of which are needed to upload a file to a private bucket? Where do I get these values from? For the bucket, when I generated an application-key, I got an applicationKey and keyId (I added read write access for the application-key), but they are applicable to the APPLICATION_KEY_PRIVATE_RO and KEY_ID_PRIVATE_RO variables in the script, so where do those three variables come from?

There is a simple typo in the signature/variable names

Hey,

So I've been using your functions and for some unknown reason the get_presgined_url functions runs 27 times everytime I call it:
def get_object_presigned_url(key, expiration_seconds, b2):
try:
response = b2.meta.client.generate_presigned_url(ClientMethod='get_object',
ExpiresIn=expiration_seconds,
Params={
'Bucket': bucket,
'Key': key
} )
print(response)
return response
except ClientError as ce:
print('error', ce)

Any idea why would that happen?

Hi,

So i'm getting up to speed with using b2 buckets and the boto library. After cloning the repo and opening the sample project in my ide, i first read thru the article at Backblaze B2 Quick Start: Using Python With the Backblaze S3 Compatible API and gathered a fairly good understanding of the code. I then tried just running it and encountered a wall of text in errors from python. So i then watched the youtube explainer video. Part 1 at least presents a greatly simplified overview, basically matching what i had gathered in reading the article. However in the video the code executes without issue, successfully making the request and receiving bucket data.

With the understanding that this should work, i created a new python file, called it sample minimal and pulled out just the basic minimal parts that should run and replicate the success that the video had. Another wall of text from python in errors and ending with "ValueError: Invalid endpoint: https://s3.us-west-002.backblazeb2.com".

I then searched the repository for issues, finding only one that didn't match my trouble, then checked branches, and found the v1.0 branch. Surprise, v1.0 works like a charm. After spending now a couple hours familiarizing myself with the project, i was quickly able to read and make sense of the simplified v1.0 version and was successful in running the code, without a mess of python errors or any other issues.

I just wanted to bring this to your attention, basically the v2.0 branch which is what downloads by default when cloning the repo is either broken or requires additional information, while the v1.0 just works. As an intro to working with B2, the successful result would be far more advantageous for new users who may not be as stubborn as i was today.

sample.py line 7 says points to more instructions, but they do not exist.

I'm not sure where it meant to link to now...
