Get an Amazon S3 object from a Multi-Region Access Point by using an Amazon SDK
The following code example shows how to get an object from a Multi-Region Access Point.
- Kotlin
-
- SDK for Kotlin
-
Configure the S3 client to use the Asymmetric Sigv4 (Sigv4a) signing algorithm.
suspend fun createS3Client(): S3Client {
// Configure your S3Client to use the Asymmetric Sigv4 (Sigv4a) signing algorithm.
val sigV4AScheme = SigV4AsymmetricAuthScheme(CrtAwsSigner)
val s3 = S3Client.fromEnvironment {
authSchemes = listOf(sigV4AScheme)
}
return s3
}
Use the Multi-Region Access Point ARN instead of a bucket name to retrieve the object.
suspend fun getObjectFromMrap(s3: S3Client, mrapArn: String, keyName: String): String? {
val request = GetObjectRequest {
bucket = mrapArn // Use the ARN instead of the bucket name for object operations.
key = keyName
}
var stringObj: String? = null
s3.getObject(request) { resp ->
stringObj = resp.body?.decodeToString()
if (stringObj != null) {
println("Successfully read $keyName from $mrapArn")
}
}
return stringObj
}
