how do I list object in bucket in Flutter?

I’m glad, cloudflare should fix this type of issues where you don’t get to see what failed, just try stuff until it works

kian•8/5/23, 6:03 PM

Yeah, it’s just how CORS works.

psx•8/5/23, 8:46 PM

Hi, I am using r2 bucket to store some data like images/videos/fonts. When I get the data using the public domain pointing to r2 bucket, images/videos are being fetched perfectly, but fonts are not being loaded and showing cors error, don't know why it is happening?

Any help/hint would be great

kev-ac•8/5/23, 9:59 PM

Do you have CORS rules set up for the bucket? If so: How do they look like?

kev-ac•8/5/23, 10:06 PM

To test it I've quickly set up a test bucket with a bare minimum CORS rule set:

[
  {
    "AllowedOrigins": [
      "*"
    ],
    "AllowedMethods": [
      "GET"
    ]
  }
]

[
  {
    "AllowedOrigins": [
      "*"
    ],
    "AllowedMethods": [
      "GET"
    ]
  }
]

It works just fine with font files and the CORS headers are added to the response.
Here's the test url: https://pub-39985ea202da4f348be027c2d73de5a9.r2.dev/Inter-italic.var.woff2

You probably want to hint the bucket to a part to the world where you expect the most uploads from (or the location of your server that interacts with the bucket the most)

For people accessing files and caching them near places of frequent access, you have the whole Cloudflare CDN

psx•8/5/23, 10:49 PM

Yes, it is working this way but I didn't want to allow all origins. Is it possible to set cors such a way, it allows get requests but not put, only allow put reqs through signed urls using s3 client library?

kev-ac•8/5/23, 10:52 PM

CORS is a client-side thing, so nothing that can be used for authorization. But: PUT requests would never go through your custom or r2.dev domain, so this won't be an issue here. For PUT requests you talk to the s3-compatible endpoint ({id}.r2.cloudflarestorage.com).

psx•8/5/23, 11:20 PM

Yes I am using the put singed urls the same way, was just curious is it safe to allow all origins or not

It’s an widget that people can use it on their website, that’s why I had to allow all origin to access the fonts

But then why images and videos were working from the public domain, I thought everything is accessible using that custom domain

I have set the cache rules to dodn’t cache my files,because I worried about I will violation of terms 2.8.

r2 + cache everything stonks

Unsmart•8/6/23, 3:15 AM

Cache is free and R2 is only single region so a cache hit will be infinitely faster than going to origin. No reason not to cache unless you need sting consistency on reads which you probably don’t

Karew•8/6/23, 11:10 AM

R2 doesn't compress data at all when you upload it, you have to compress the file before uploading it and set the Content-Encoding: gzipContent-Encoding: gzip.

Cloudflare's whole network does transparent encoding when it can

I have not personally tried brbr encoding, but it works both ways with gzipgzip right now (it was something they needed to fix early on in R2)

So you can:
(1) Don't compress the JSON before you upload it. Cloudflare will still encode/compress it only the fly for gzipgzip or brbr clients
(2) Upload a gziped JSON. Cloudflare will uncompress it on the fly for identityidentity encoding or just send the file for gzipgzip. I am not sure what happens for brbr here.

Is it possible to confirm the location of an R2 Bucket?

kian•8/6/23, 7:59 PM

https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetBucketLocation.html

GetBucketLocation - Amazon Simple Storage Service

Returns the Region the bucket resides in. You set the bucket's Region using the LocationConstraint request parameter in a CreateBucket request. For more information, see CreateBucket .

I don’t think the log endpoint is meant to enumerate all of your bucket objects that way. You should use the S3 API if you want to list or manage the bucket objects
