Provides an http4s client middleware that authenticates requests with AWS Auth Signature V4.
To get started with sbt, simply add the following line to your build.sbt file.
libraryDependencies += "com.github.fd4s" %% "http4s-aws" % "<version>"Example of use with S3:
import scala.concurrent.ExecutionContext.{global => ec}
import cats.implicits._
import cats.effect._
import com.amazonaws.auth.DefaultAWSCredentialsProviderChain
import org.http4s.{Service => _, _}
import org.http4s.Method._
import org.http4s.client._
import org.http4s.client.dsl.io._
import org.http4s.client.blaze._
import com.github.fd4s.http4s.aws._
import com.github.fd4s.http4s.aws.model._
implicit val cs: ContextShift[IO] = IO.contextShift(ec)
BlazeClientBuilder[IO](ec)
.resource
.map { client =>
AwsSigner(
CredentialsProvider.fromAwsCredentialProvider[IO](
new DefaultAWSCredentialsProviderChain()
),
Region.`eu-west-1`,
Service.s3
)(client)
}
.use { client =>
for {
url <- IO.fromEither(Uri.fromString("hhttps://test.s3-eu-west-1.amazonaws.com/test.txt"))
req <- GET(url)
res <- client.expect[String](req)
} yield res
}
.unsafeRunSync()
Happy coding!
