I found myself struggling to enable https support for our akka-http java application. The documentation page (https://doc.akka.io/docs/akka-http/current/server-side/server-https-support.html) should be helping, but for some reason in my case it does not.
From what I got from that page - the idea is to obtain an HttpsConnectionContext
instance and use it as a parameter for the http.setDefaultClientHttpsContext(...)
method call before actually doing some route binding.
What I have so far
Code that creates an SSLContext
from the configuration:
public static SSLContext getSslContext(String path, ActorSystem system) {
final AkkaSSLConfig sslConfig = AkkaSSLConfig.get(system);
final Config overrides = system.settings().config().getConfig(path);
final Config defaults = system.settings().config().getConfig("ssl-config");
final SSLConfigSettings config = SSLConfigFactory.parse(overrides.withFallback(defaults));
return new ConfigSSLContextBuilder(
new AkkaLoggerFactory(system),
config,
sslConfig.buildKeyManagerFactory(config),
sslConfig.buildTrustManagerFactory(config)
).build();
}
Actual peace of configuration:
akka.ssl-config {
trustManager = {
stores = [
{ type: "JKS" , path: "xxx-truststore.jks", password = "xxx"}
]
}
keyManager = {
stores = [
{ type: "JKS" , path: "xxx-keystore.jks", password = "xxx"}
]
}
}
Using them to enable https:
final SSLContext sslContext = getSslContext("akka.ssl-config", system);
final HttpsConnectionContext httpsContext = ConnectionContext.https(sslContext);
http.setDefaultClientHttpsContext(httpsContext);
final CompletionStage<ServerBinding> binding =
http.bindAndHandle(routeFlow, ConnectHttp.toHost("localhost",443), materializer);
But that actually does nothing. If I try to make some https call to the server I get the following exception:
Illegal request, responding with status '400 Bad Request': Unsupported HTTP method: The HTTP method started with 0x16 rather than any known HTTP method. Perhaps this was an HTTPS request sent to an HTTP endpoint?
I’m probably missing something, but I have no idea what
