Helper to evaluate the signing headers for HTTP requests to Amazon Web Services. This is a Scala port of (part of) the Java aws-signing-request-interceptor.
I originally needed this library to support AWS' Elasticsearch Service, but this library is 'AWS service agnostic'.
In your build.sbt file,
resolvers += Resolver.jcenterRepo
libraryDependencies += "io.ticofab" %% "aws-request-signer" % "0.1.0"
The procedure to sign AWS Api requests is described on the official documentation. The idea is that each request must be signed through the evaluation of a hash which depends on the very request itself. The resulting string can then be added to the request either as a header or as a query param. This library focuses on the header way.
You first need to instantiate the signer, for example:
val awsCredentialProvider = new StaticCredentialsProvider(new BasicAWSCredentials("YOUR-ID", "YOUR-SECRET"))
val service = "es"
val region = "eu-central-1"
def clock(): DateTime = DateTime.now
val signer = AwsSigner(awsCredentialProvider, region, service, clock)
Then use it for each request, via
def getSignedHeaders(uri: String,
method: String,
queryParams: Map[String, String],
headers: Map[String, String],
payload: Option[Array[Byte]]): Map[String, String]
Check the examples in the test folder of this project. Once you have the headers, add them to your HTTP request and fire it.
