Note, you can set that as the default ACL for the library

But if you want the files to be public in the first place, then change your bucket settings, lol

You can generate signed URLs with the

getAuthenticatedURL()

method on the SDK

A signed url is accessible by whoever possesses it for the time period defined (default 60 minutes)

So, if you want the bucket to be private, then you create a signed url to allow a browser to hit a file

Creating the signed url is fast and doesn't hit S3

So you can embed that url in html or redirect a logged in user to download, etc

I just boarded a plane so going offline. You can see some examples if creating authwnticated urls in the unit test suite. We're working on the docs for this library.

If it's an image, you put it in an image tag. If it's a PDF, you redirect the browser to it, etc

There's really nothing special about it- it's just a URL to a file like any other

i can serve img through function, not an issue, now if the bucket is in different region, it actually ends up in the us, let me see if i can try to change the bucket by passing an extra argument

ok, i gave it more try and still can't figure out this section, i updated my function to pass the location where the bucket is created https://trycf.com/gist/17b830f6552bde1d6478d9f82038a41d/lucee5?theme=monokai Error i am getting i think i am missing a very small portion of isse, where it matches the cettificate using a *, but does actually connects to that and serve the file *Struct*charsetstringerrordetailstringUnknown host: Certificate for <s3.1111.files.s3.ca-central-1.amazonaws.com> doesn't match any of the subject alternative names: [*.s3.ca-central-1.amazonaws.com, s3.ca-central-1.amazonaws.com, *.s3-ca-central-1.amazonaws.com, s3-ca-central-1.amazonaws.com, *.s3.dualstack.ca-central-1.amazonaws.com, s3.dualstack.ca-central-1.amazonaws.com, *.s3.amazonaws.com, *.s3-control.ca-central-1.amazonaws.com, s3-control.ca-central-1.amazonaws.com, *.s3-control.dualstack.ca-central-1.amazonaws.com, s3-control.dualstack.ca-central-1.amazonaws.com, *.s3-accesspoint.ca-central-1.amazonaws.com, *.s3-accesspoint.dualstack.ca-central-1.amazonaws.com]filecontentstringConnection FailureheaderstringmimetypestringUnable to determine MIME type of file.responseheader*Struct*status_codenumber0status_textstringConnection FailurestatuscodestringConnection Failure.

That's not how this works

Here is what i have to fetching and displaying

any function fetchFile(required clientID="#url.clientID#", required gameSheet="") {
		var serveFile = '';
		try {
			var bucketName = 's3.'&lcase(arguments.clientID)&'.files';
			var presignedURL = getAuthenticatedURL(bucketName, arguments.gameSheet,60,true);
			serveFile = '<img src="#presignedURL#"/>'
		} catch (any cfcatch) {
			serveFile = 'Error! #cfcatch.detail# #cfcatch.message#';
		}
		return serveFile;
	}

What does the last code do when run?

Also, the try/catch seems unnecessary

What does it show?

No clue about your connection error. Sounds like a configuration issue in your local network.

trying itlike this

serveFile = mimetype contains 'image' ? '<img src="#sFile#" border="1" style="margin-bottom:15px; width:100%;"/>' : '<iframe src="#sFile#" width="100%" height="400" scrolling="yes" style="margin-bottom:15px" allowfullscreen="allowfullscreen"></iframe>';
		return serveFile;

its downloading the file with empty iframe, i know i have to use cfcontent or cfheader but where exactly not sure

Just redirect the browser to it

Think to yourself how you'd solve this if it wasn't S3 and was just a normal link to any old file. And then do that 🙂
