compass-download-kotlin

compass-download-kotlin

This is a clone of compass-numapp-downloader, written in Kotlin instead of Python. This is why the interface component does not depend on a Python installation.

IMPORTANT HINT

You need to use at least Java 8 Update 161, Java 9 or newer, due to the fact that older versions cannot use AES with more than 128 Bit due to legal reasons.

Example usage

To load the certificate, public and private key files in the sample code below, put them under src/main/resources:

suspend fun main(args: Array<String>) {
    val privateKeyFile = Paths.get(ClassLoader.getSystemResource("private_key.pem").toURI()).toFile()
    val publicKeyFile = Paths.get(ClassLoader.getSystemResource("public_key.pem").toURI()).toFile()
    val certFile = Paths.get(ClassLoader.getSystemResource("cacert.pem").toURI()).toFile()
    val downloader = CompassDownloader(
        publicKey = PemUtils.loadPublicKey(publicKeyFile),
        privateKey = PemUtils.loadPrivateKey(privateKeyFile),
        cert = PemUtils.loadCert(certFile)
    )
    val decryptQueueItems = downloader.decryptQueueItems(downloader.getAllQueueItems())
    println(decryptQueueItems)


}

You can also use the downloader object to add or update questionnaires:

val questionnaire = Questionnaire().apply {
    url = "https://my-questionnaire-url.de/"
    version = "1.0"
    // [...]
}

val accessToken = downloader.retrieveAccessToken()

val parser = FhirContext.forR4().newJsonParser()
downloader.addQuestionnaire("myName", parser.encodeResourceToString(q), accessToken)
//or: downloader.updateQuestionnaire(...) if you want to update
val jsonString =
    downloader.retrieveQuestionnaireStringByUrlAndVersion("https://my-questionnaire-url.de/", "1.0", accessToken)
