HI understand that, but are they actual files or just blobs simulating the uploaded files
HThey are actual files. They don't have filenames/metadata, but they do exist as actual files
HPerfect. Thanks for the response!
Hlol just found this line of code funny
PWondering if anyone can shed some light on an issue im facing with r2.dev access
loads in discord, but no where else for me

POk thanks i was just testing but i might hook up a custom domain. Appreciate the information
YHello. I have a frontend app that uses a PHP backend. I have image files that only authenticated users should be able to view. Authentication is done via cookies and headers against the PHP server.
The frontend app gets data from PHP including the urls of said images and then these urls are embedded using <img> tags.
Currently i have an .htaccess file that re-routes requests to these images to a php function that checks if the user is authenticaed and authorized and if so serves the image from disk.
I would like to move all the images to an R2 instance.
I would like to issue a cookie for the user when they log in and i want the users to use that cookie to get the images from R2 directly.
Is that at all possible?

Y@Space - Ping in replies I read about signed URLs.
I would like to avoid re-calculating (pre-signing) the image urls each time they are served.
Is there a way I can issue a cookie or an access token that is good for say 24 hours and then the frontend app can use this cookie or token on all of it resquests to R2?

YHmm interesting... i would still need to cache it my PHP server to not re-sign it for as long as its valid
IKeep in mind that pre-signing doesn't do any network IO and is simply computing a URL based on input parameters - so it's fairly lightweight to compute.
YThank you. That's good to know
CR2 Custom Domains are read-only and only allow you to get files you know the names/keys of. There's no listing or uploading
CI'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"

IHi everyone, I'm new to R2. I want to know if a domain connection is required to make a bucket public? Do I need to buy a new domain for this? (I don't want to use R2.dev subdomain as it is ratelimited).
Thank you!
Thank you!
I(Sorry I know for sure that this question has been answered before but I couldn't find it for the moment)
IFound the answer which is YES, thank you!
II 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? 
CYou just enter the subdomain/hostname under Connect Domain
Iokay thank you
Iis this normal, I have nothing on my bucket yet and already the number of A and B class operations increases randomly?
Uviewing the dashboard makes requests to the bucket
IAh, okay. Even though the numbers seem high because I just created the bucket, it's good to know anyway. Thanks!
CHi.
Looks like Sippy cannot work with files whose names contain non-Latin characters.
Two examples of links copied from the GCS console and translated into links for R2 with a domain bound to a bucket.

KKAlthough I would consider filenames like this one to be a smell https://r2.qq.land/game/03bd26d3-ecb6-4a89-b130-b771e6d1dc87/QQ_%D0%B4%D0%BE%D1%81%D1%82%D0%B0%D1%82%D1%8C%20%D0%BD%D0%BE%D0%B6%D0%B8%20%D0%BA%D0%BE%D0%BF%D0%B8%D1%8F1-cAZHN4ZClv7y-115610.jpg
CThis is User Generated Content and this does not mean that files with such names should not be processed.
KYou 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
CHowever, 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.
IOne of the issues with letting users name their own files is that they could upload a file with / I think?
IThen suddenly they've created a new "directory" in your R2 bucket.
HGood think you can't do directory traversal ala
../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.
DHi, I'm new to R2 and have read the docs and tried to use the Postman collection. I am not using S3 but simply want to push files via an API to R2. I do not find a proper APi documentation on how to send proper requests. Can anybody point me to what I might be missing please?
CThe API you want to use is the S3 Compatible API, only publicly documented option
Dso I have to do the AWS signing stuff even though I'm not using S3?
CYou will be using the S3 Compatible API, so yes
CThere'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
Dthanks @Chaika - no sdk for Java right? just double checking
CThere'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
Dthank you Chaika for the quick help, I appreciate it
JHi guys. Im having a problem with R2 usage metrics, when i obtain a object a just one time from s3 api, the metrics put a class A operation. Why this is happening??
JThen, how can i measure operations without dashboard?
JWhere is located at?
JOk, thanks 
JHi.
I configured a R2 bucket to use a custom domain, but when I try to access its objects from browser, I receive a 403 error code.
What could be the cause of it, and how can I fix it?
