I'm using an AWS Lambda function to create a file and save it to my bucket on S3, it is working fine. After executing the putObject
method, I get a data
object, but it only contains an Etag
of the recently added object.
s3.putObject(params, function(err, data) { // data only contains Etag });
I need to know the exact URL that I can use in a browser so the client can see the file. The folder has been already made public and I can see the file if I copy the Link from the S3 console.
I tried using getSignedUrl
but the URL it returns is used for other purposes, I believe.
Thanks!
You can get the resource URL either by calling getResourceUrl or getUrl . AmazonS3Client s3Client = (AmazonS3Client)AmazonS3ClientBuilder. defaultClient(); s3Client. putObject(new PutObjectRequest("your-bucket", "some-path/some-key.
In the Amazon S3 console, choose your S3 bucket, choose the file that you want to open or download, choose Actions, and then choose Open or Download. If you are downloading an object, specify where you want to save it. The procedure for saving the object depends on the browser and operating system that you are using.
The SDKs do not generally contain a convenience method to create a URL for publicly-readable objects. However, when you called PutObject, you provided the bucket and the object's key and that's all you need. You can simply combine those to make the URL of the object, for example:
So, for example, if your bucket is pablo
and the object key is dogs/toto.png
, use:
Note that S3 keys do not begin with a /
prefix. A key is of the form dogs/toto.png
, and not /dogs/toto.png
.
For region-specific buckets, see Working with Amazon S3 Buckets and AWS S3 URL Styles. Replace s3
with s3.<region>.amazonaws.com
or s3-<region>.amazonaws.com
in the above URLs, for example:
If you are using IPv6, then the general URL form will be:
For some buckets, you may use the older path-style URLs. Path-style URLs are deprecated and only work with buckets created on or before September 30, 2020. They are used like this:
Currently there are TLS and SSL certificate issues that may require some buckets with dots (.
) in their name to be accessed via path-style URLs. AWS plans to address this. See the AWS announcement.
Note: General guidance on object keys where certain characters need special handling. For example space is encoded to + (plus sign) and plus sign is encoded to %2B. Also here.
in case you got the s3bucket and filename objects and want to extract the url, here is an option:
function getUrlFromBucket(s3Bucket,fileName){ const {config :{params,region}} = s3Bucket; const regionString = region.includes('us-east-1') ?'':('-' + region) return `https://${params.Bucket}.s3${regionString}.amazonaws.com/${fileName}` };
