Connect to Amazon account using Scala - scala

Question

I want to connect to my Amazon account in order to delete resources inside my s3 storage.
I have the access key and secret key, and this is how I started to build my connection to Amazon:
def connectToAmaozn(): Unit = {
val AWS_ACCESS_KEY=conf.getString("WebRecorder.PushSession.AccessKey")
val AWS_SECRET_KEY=conf.getString("WebRecorder.PushSession.SecretKey")
val AWSCredentials = new BasicAWSCredentials(AWS_ACCESS_KEY,AWS_SECRET_KEY)
}
Can you elaborate on how I may do this?

Answer 1

I used this solution to get bucket name and number of objects:
import scala.collection.JavaConversions._
import com.amazonaws.auth.{AWSStaticCredentialsProvider, BasicAWSCredentials}
import com.amazonaws.services.s3
import com.amazonaws.services.s3.model.{GetObjectTaggingRequest, ObjectListing, S3ObjectSummary}
import com.amazonaws.services.s3.{AmazonS3Client, AmazonS3ClientBuilder}
import com.clicktale.pipeline.framework.dal.ConfigParser.conf
import com.amazonaws.services.s3.AmazonS3Client
import com.amazonaws.auth.BasicAWSCredentials
import com.amazonaws.services.s3.AmazonS3Client
import com.amazonaws.services.s3.model._
import scala.language.postfixOps
class Amazon {
val AWS_ACCESS_KEY = conf.getString("WebRecorder.PushSession.AccessKey")
val AWS_SECRET_KEY = conf.getString("WebRecorder.PushSession.SecretKey")
val bucketName = "nv-q-s3-assets-01"
val provider = new AWSStaticCredentialsProvider(new BasicAWSCredentials(AWS_ACCESS_KEY, AWS_SECRET_KEY))
val client = AmazonS3ClientBuilder.standard().withCredentials(provider).withRegion("us-east-1").build()
// def connectToAmazon(): Unit = {
//
// val provider = new AWSStaticCredentialsProvider(new BasicAWSCredentials(AWS_ACCESS_KEY, AWS_SECRET_KEY))
// val client = AmazonS3ClientBuilder.standard().withCredentials(provider).withRegion("us-east-1").build()
def removeObjectsFromBucket(){
println("Removing objects from bucket...")
var object_listing: ObjectListing = client.listObjects(bucketName)
var flag: Boolean = true
while (flag) {
val iterator: Iterator[_] = object_listing.getObjectSummaries.iterator()
while (iterator.hasNext) {
val summary: S3ObjectSummary = iterator.next().asInstanceOf[S3ObjectSummary]
client.deleteObject(bucketName, summary.getKey())
}
flag=false
}
}
def countNumberOfObjectsInsideBucket(): Unit ={
var object_listing: ObjectListing = client.listObjects(bucketName)
var flag: Boolean = true
var count=0
while (flag) {
val iterator: Iterator[_] = object_listing.getObjectSummaries.iterator()
while (iterator.hasNext) {
val summary: S3ObjectSummary = iterator.next().asInstanceOf[S3ObjectSummary]
count+=1
}
flag=false
println("Number of objects are: " + count)
}
}
}

You need a AWSCredentialsProvider:
val provider = new AWSStaticCredentialsProvider(
new BasicAWSCredentials(AWS_ACCESS_KEY,AWS_SECRET_KEY)
)
and then use it to create the client:
val client = AmazonS3ClientBuilder
.standard
.withCredentials(provider)
.withRegion("us-west-1") // or whatever your region is
.build
