Hi, what is the best way to sync two R2 buckets?

I gather rclone or Super Slurper are two options as per docs. Any experience?

after spending 16 hours searching for a solution, I also do not. I am wondering if there is any way of sanitizing media files before putting them into the r2 within a worker. which is my actual motivation.

Z

zanzibar•11/29/24, 1:49 AM

at least there is a good way with images:
import * as photon from '@cf-wasm/photon'

// fileData comes from a request PUT request (mimeType: header, image: body) to this worker
const processFile = async (fileData: Uint8Array, mimeType: string) => {
try {
let file;

if (mimeType.startsWith('image/')) {
// Create a new image file with photon
file = photon.PhotonImage.new_from_byteslice(fileData);
console.log('Image successfully recreated.');
}
return file;
} catch (error) {
console.error('Failed to load media file:', error);
throw new Error('Invalid media data or error during processing.');
}
};

Hi, I'm trying to debug CORS on R2. I've configured a CORS policy on my R2 bucket in the Cloudflare dashboard, but when doing a preflight request I'm getting 403

<?xml version="1.0" encoding="UTF-8"?><Error><Code>Unauthorized</Code><Message>CORS not configured for this bucket</Message></Error>

<?xml version="1.0" encoding="UTF-8"?><Error><Code>Unauthorized</Code><Message>CORS not configured for this bucket</Message></Error>

<?xml version="1.0" encoding="UTF-8"?><Error><Code>Unauthorized</Code><Message>CORS not configured for this bucket</Message></Error>

<?xml version="1.0" encoding="UTF-8"?><Error><Code>Unauthorized</Code><Message>CORS not configured for this bucket</Message></Error>

(I'm using presigned URLs)

Does it take some time until CORS policy changes are propagated? Or is something wrong with my configuration?

M

maurus•11/29/24, 9:36 AM

are you saying that they only apply to the custom domain and not the

*.r2.cloudflarestorage.com

*.r2.cloudflarestorage.com

*.r2.cloudflarestorage.com

*.r2.cloudflarestorage.com one?

yupp, that is precisely what i will go for now. it seemed all too good to be true to sanitize uploads at the edge. as i had my user verification, DB access and such all working fine in the worker. but with the security of my users in mind, who will be exposed to other user's uploads - i realize that i can't weasel around a proper backend server anymore hehe

You could also fetch directly from r2, but use pre-signed urls which can be generated by a backend

Z

zanzibar•11/29/24, 1:55 PM

I use an R2 to store media files from my users and those have resticted access (users can purchase other user's contents and gain access). Currently, I would use a backend for user verification and generate presigned URLs if a user is permitted to view the content. is there a better way of handling this scenario? one thing coming to my mind is that it would be great to cache those contents for users who have access rights.. as they might request the same files over an over

Thanks, I will happily check it out as I am new to this sort of infrastructure. Could you please elaborate on why presigned URLs are not recommended? Or do you happen to have a readable guide on how to use hmac auth?

zanzibar•11/29/24, 3:18 PM

thanks again! then it seems to be the way to go for my use case. yet I am unable to find a guide on how to implement it. my client would make a request to my backend for a particular post. my backend will validate that the user is permitted to read the media files linked in it. now the backend shall give my client access to view the files - shall the backend create the r2.yourdomain.TLD/<auth-and-objectkey> using the user's auth url and return it to the end user? i cannot find any configurations within cloudflare atm :/

zanzibar•11/29/24, 3:42 PM

hmmm.. I will certainly be able to validate my user on my backend and create an appropriate url. yet I don't understand what i need to configure in cloudflare and why the pro subscription is needed. so far I do use a custom domain, proxying and dns by cloudflare with a free plan.

zanzibar•11/29/24, 3:52 PM

so HMAC is then a feature within the Security/WAF custom rules.. I see! thank you kindly. let's say i have set up a custom rule to verify the incoming HMAC token to grant access to my r2's resources. where does the caching come into play at this point?

Z

zanzibar•11/29/24, 3:57 PM

alright, thanks! i thought that if i want to cache resources behind an authentication, the settings would be different/somewhere particular for that case. really cool that you take time to help people here, much appreciated

would it be possible to use a worker to validate hmac requests, as long as i do not publish my application? if so, what are the drawbacks in comparison to WAF?
