Yes. It's required to help prevent abuse.

This will be problematic for those living in countries where international bank accounts are not available, especially since they only want to use the free version and Cloudflare may limit their account if their bandwidth increases.

boldpixOP•11/11/24, 1:05 PM

Can anyone recommend a free cloud storage service that doesn't demand bank details for initial signup and is actually free to use?

Hello guys, do you have any idea why the cache doesn't work? I've got a bunch of small images stored in R2 and displayed on my website. I have a Cache rule set, but there are still a lot of Class B operations.

RoyalFlashhh•11/11/24, 3:31 PM

from 10kb to 1mb

RoyalFlashhh•11/11/24, 3:36 PM

Not sure if I can filter by hostname. But this screenshot for whole website

RoyalFlashhh•11/11/24, 4:01 PM

I just thought if I set cache to 1 year then there shouldn't be any Class B operations. Thanks anyway

Troubleshooting 403 / CORS issues with R2

So, your assets aren't loading because you are getting a CORS error despite having setup everything correctly?
Let's try troubleshooting.

In your browser console, do you see a 401/403 error right above the CORS error? If yes, then you aren't actually dealing with a CORS issue! If you do have a CORS issue, head to the last section.

If you are using a Custom domain

Go to the Network tab and find the failing request (you may need to reload the page, since only requests after opening the developer tools are logged).
You need to check the response headers for the following two headers:

cf-cache-statuscf-cache-status
cf-mitigatedcf-mitigated

### If you have a cf-mitigatedcf-mitigated header

Your request was blocked by one of your WAF rules. Go to Security Events and look for what service blocked your request.

If you don't have a `cf-cache-statuscf-cache-status` header

Your request was blocked by Hotlink Protection.
Go to your dashboard and disable it or write a configuration rule to only disable on your Custom domain

If you are using the S3 API

Your request is very likely incorrectly signed.
Try executing the request via curl to inspect the real response returned by the S3 api and then tackle that issue.
Once your request is correctly signed, you'll receive the proper CORS headers.

If it's actually CORS

Here are some common issues with CORS configurations:

ExposeHeadersExposeHeaders is missing headers like ETagETag
AllowedHeadersAllowedHeaders is missing headers like
```
Authorization
```
```
Authorization
```
or Content-TypeContent-Type
AllowedMethodsAllowedMethods is missing methods like POSTPOST/PUTPUT (you do not need to include OPTIONSOPTIONS)

Rakhim•11/11/24, 4:44 PM

I'm using R2 to serve images uploaded by users of my app. I'm tempted to disable public access to the R2 bucket, and serve images via worker. I'm wondering if there are downsides to this? Would it significantly worsen the performance due to worker invocation? What's the general good practice when using R2-files to the public?

Original message was deleted

Rakhim•11/11/24, 4:55 PM

My users have accounts at subdomain.domain.com, and I’d like their images to appear to be served from their subdomains, rather than from the central assets.domain.con

Rakhim•11/11/24, 4:57 PM

Create a bucket per user? Hmm.. maybe. I’d have to check on limits. I don’t know yet how many users I’ll have, could be thousands.

Original message was deleted

Rakhim•11/11/24, 5:12 PM

Thanks for the info. I think I'll stick to one bucket for now.

Dieter•11/11/24, 5:26 PM

Good evening, I just wanted to check/ask to be sure, do file fetches in public buckets count towards Class B operations?

(asking because I worry that if they do, someone could technically spam requests on the bucket and could perhaps cost me quite a bit of money)

Dieter•11/11/24, 5:32 PM

Hmm ok, thank you :firefly: !
Not sure where I can even set up rate limiting but I'll have a look.

I'm just trying to prevent that I wake up to a multi hundred/thousand dollar bill at some point

But it seems like with caching (which should be enabled) and rate limiting perhaps it should be fine (its a bucket with a bunch of relatively small images (KB's), and while class B operations are generally a whole lot cheaper, I do want to be cautious)

Dieter•11/11/24, 7:32 PM

oh I have, set them up at like 80 % of the free tier for now to see how long it takes until I hit it

I just wish there was some option to like disable the DNS domain after a certain threshhold is met (like idk, disable the bucket's DNS record after 25 million class B operations for example)

Dieter•11/11/24, 7:33 PM

perhaps it'd be possible with the cloudflare API? maybe I should check out if that's a possibility

Original message was deleted

Dieter•11/11/24, 7:35 PM

where can you select a webhook for that? all I can see is a notification email

Dieter•11/11/24, 7:38 PM

ah there's a Destinations tab

Dieter•11/11/24, 7:42 PM

Hmm, when checking the wiki it says it needs a professional or higher plan but I can make them anyway

Dieter•11/11/24, 7:50 PM

yeah but I don't mind having to create a smal script/program for that tbh

Dieter•11/11/24, 7:50 PM

I'll take it if it means I don't have to worry at all :D

I know its unlikely but still, I'm rather 100 % sure than 99 %

Dieter•11/11/24, 7:51 PM

thanks for the help :HuTaoHeart2:

How do I list objects in the worker using a key percentage?

Brunão77•11/11/24, 8:33 PM

Is there a way to indicate in R2 that all objects that are more than 7 days old since they were uploaded and whose key starts with the word "clip" are deleted?

Brunão77•11/11/24, 9:09 PM

want to tell r2 to do

Wamy•11/11/24, 11:50 PM

Is there a way to serve requests to an R2 bucket using workers from a specific URL that doesn't include the file path?

For example the url

https://r2.storage.com/hash?token=user_token

will serve a file located at my r2 bucket without redirecting to somewhere for example like https://r2.cloudflarestorage.com/mybucket/myfile.txt

The worker would lookup the file by using the hash and verify the request internally using the user token

Wamy•11/11/24, 11:50 PM

basically I want a custom domain that hides the exact location of the file so that my server signs requests

Wamy•11/11/24, 11:51 PM

I also still need to take advantage of the cloudflare cache

Isaac McFadyen•11/12/24, 12:39 AM

Using Workers: absolutely, you'll need to write the Worker yourself but you can use the R2 bindings from inside a Worker to fetch the file based on the URL.

Isaac McFadyen•11/12/24, 12:39 AM

https://github.com/kotx/render is a good example of a Worker that does that and which is fairly fully-featured

thank you, the question is if it will still be as fast as r2 directly

Wamy•11/12/24, 1:49 AM

render looks very good and Ill be stealing code for sure

Wamy•11/12/24, 1:50 AM

at least to see how they do it initially

teena•11/12/24, 4:40 AM

I've configured my files from R2 to be served from:
assets.mydomain.comassets.mydomain.com
So, fetching and displaying images on my site works as expected, for example,
assets.mydomain.com/some-random-id.pngassets.mydomain.com/some-random-id.png

I've added a download button on each image, but I can't get past the CORS errors.
I've followed almost every solution I found on the internet, including adding transform headers rules, but still no luck.
I've set up CORS rules on the bucket, but nothing!

Does anyone here have experience with this?
Help would be appreciated!

My server end code can generate a pre-signed url, and I can upload a file using the pre-signed url when running curl on server. But I got an Unauthorized error when I issued the same curl command from my laptop's terminal.
