sts

Security Token Service

The STS connector provides the following Actions:

 *  AssumeRole
 *  AssumeRoleWithWebIdentity

The client APIs utilise the http4k-aws module for request signing, which means no dependencies on the incredibly fat Amazon-SDK JARs. This means this integration is perfect for running Serverless Lambdas where binary size is a performance factor.

Example usage

const val USE_REAL_CLIENT = false

fun main() {
    val region = Region.of("us-east-1")
    val roleArn = ARN.of("arn:aws:sts:us-east-1:000000000001:role:myrole")

    // we can connect to the real service or the fake (drop in replacement)
    val http: HttpHandler = if (USE_REAL_CLIENT) JavaHttpClient() else FakeSTS()

    // create a client
    val client = STS.Http(region, { AwsCredentials("accessKeyId", "secretKey") }, http.debug())

    // all operations return a Result monad of the API type
    val assumeRoleResult: Result<AssumedRole, RemoteFailure> = client.assumeRole(roleArn, "sessionId")
    println(assumeRoleResult)
}

Default Fake port: 20434
