R2 Custom Domains are read-only and only allow you to get files you know the names/keys of. There's no listing or uploading

I'm having an issue when using the example in https://developers.cloudflare.com/r2/api/s3/presigned-urls/#presigned-url-alternative-with-workers

Do I need to specify the accessKeyId and secretAccessKey when signing the request?

The presign gives the error "Invalid Argument: Credential access key has length 0, should be 32"

I have already a domain, and apparently I can use a subdomain for making my bucket public, is there any resource that could help me set this up? because I accidently connected my main domain and one minute later I received an email complaining that my app crashed :blob_sweat:. So, I don't want to repeat the same mistake, is creating a subdomain and connecting it to a bucket documented somewhere?

Two examples of links copied from the GCS console and translated into links for R2 with a domain bound to a bucket.

This is User Generated Content and this does not mean that files with such names should not be processed.

K

Karew•3/18/24, 9:04 AM

You should not be letting users name the file keys you store in S3-like services, you should ideally track that filename seperately somehow and store the file under a predictable key

C

crux•3/18/24, 9:06 AM

However, this is a bug. Files with such names are possible, do not violate any standards and work with direct distributions from other S3-like services. In addition, I want to serve files directly from R2/S3, and not waste resources on retrieving a separately stored name.

I

Isaac McFadyenOP•3/18/24, 12:13 PM

One of the issues with letting users name their own files is that they could upload a file with / I think?

I

Isaac McFadyenOP•3/18/24, 12:13 PM

Then suddenly they've created a new "directory" in your R2 bucket.

This is not about how to “correctly” host user files. The point is that Sippy is expected to correctly migrate a file with URL-coded characters in the name.

The API you want to use is the S3 Compatible API, only publicly documented option

You will be using the S3 Compatible API, so yes

C

Chaika•3/18/24, 2:15 PM

There's examples here: https://developers.cloudflare.com/r2/examples/, and lots of libraries which support S3 which mostly just work with R2, as long as you configure them right

There's an AWS SDK for Java which you can use. The point of using the S3 Protocol rather then reinventing the wheel is that there are tons of existing libraries which work

Hey all. Got a weird problem with R2 in an account of a client of ours. We host the images for their WordPress site in R2. Some days ago, it looks like their R2 subscription was cancelled, and ever since we've not been able to enable it back. Images are down in the site, client's upset, I'm sweating bullets.

I see there is a billing migration going on, I imagine this issue might be related to that, but does any one know a workaround for this?

Btw, I have pressed the "Billing" link in the upper alert and it doesn't show any subscription to be re-enabled.

DeleteObjectCommand

DeleteObjectCommand

DeleteObjectCommand

DeleteObjectCommand is technically not supported yet but are there any other ways to do this from workers?

Keep in mind that pre-signing doesn't do any network IO and is simply computing a URL based on input
