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.

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:

So, fetching and displaying images on my site works as expected, for example,

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.

What are the possible reasons?

Guys I had 3 R2 buckets and I was using teh same api key to connect and it was working fine, butI created the 4th bukcet and allowed that bucket in the api key but for some reason its not working..

Please do not post your question in multiple channels/post it multiple times per the rules at ⁠#

welcome-and-rules. It creates confusion for people trying to help you and doesn't get your issue or question solved any faster.

I am using r2 api token

Manoj from ONEMCO•11/12/24, 8:53 AM

Yes, still failing and I tried that few time readding it

Manoj from ONEMCO•11/12/24, 8:59 AM

all the bucket now stopped working ... and not connecting

Manoj from ONEMCO•11/12/24, 8:59 AM

seems like create all the required buckets first and then create the api key... other wise it will be an issue

Manoj from ONEMCO•11/12/24, 8:59 AM

only option is to roll and get new set of key and that sucks... is there any other way around it?

Manoj from ONEMCO•11/12/24, 9:08 AM

well the issues started when I created the 4th bucket and it was not connecting… so to fix it I changed the api key settings from all to the manually select the bucket and selected all 4 bucket, and now the 4th bucket is not conneting… and now I am not even to add the existing buckets to the clients as well….

Manoj from ONEMCO•11/12/24, 9:08 AM

There has to be a way to refresh it to use the same API keys

Manoj from ONEMCO•11/12/24, 9:10 AM

thought crossed my mind.. may be leave it for couple of hours and then try it

Manoj from ONEMCO•11/12/24, 9:25 AM

sure, I will create a new token and try it… I am out now on my ipad, I will be back in couple of hours…

Is there anyway to use a custom sub domain without it being on cf dns? I have it linked to vercel for registration reasons, so i cant move the dns to cloudflare

ella•11/12/24, 11:50 AM

by move it i meant change the ns, i need to have it linked to vercel for automatically registering subdomains

ella•11/12/24, 11:51 AM

nope

It is possible to list a part of the string using r2. in the case when I pass example/arquivo.jpg. Where would I bring all the example files/

new credential works fine

Manoj from ONEMCO•11/12/24, 12:50 PM

So the issues is that if you create a storage bucket you need the new credentials.. which should not be the case

uhh so the r2 endpoint started giving me 403 errors out of nowhere saying . I don't think I have changed anything in the environment that would cause this. I also tried changing the api key and it's still giving the same error. Am I the only one with this issue?

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:

### If you have a 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 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:

is missing headers like
is missing headers like or
is missing methods like / (you do not need to include )

its not 403

Deleted User•11/12/24, 4:40 PM

its cors

Deleted User•11/12/24, 4:41 PM

and for the bttom section

Deleted User•11/12/24, 4:41 PM

i have that

Deleted User•11/12/24, 4:41 PM

its broken again

its weird as hell
