Dapatkan objek Amazon S3 dari Multi-Region Access Point dengan menggunakan AWS SDK

Konfigurasikan klien S3 untuk menggunakan algoritma penandatanganan Asymmetric Sigv4 (Sigv4a).

        suspend fun createS3Client(): S3Client {
            // Configure your S3Client to use the Asymmetric SigV4 (SigV4a) signing algorithm.
            val sigV4aScheme = SigV4AsymmetricAuthScheme(DefaultAwsSigner)
            val s3 = S3Client.fromEnvironment {
                authSchemes = listOf(sigV4aScheme)
            }
            return s3
        }

Gunakan Multi-Region Access Point ARN sebagai ganti nama bucket untuk mengambil objek.

    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
    }
