To enable request logging, add the following to your play application config:
play.http.filters=io.flow.play.util.LoggingFilter
By default, all HTTP methods will be logged. To only log a specific subset of methods, add the following:
play.http.filters.logging.methods=["GET", "PUT"]
A CORS request handler is provided. To enable, add the following
to your play application config (instead of LoggingFilter
above):
play.http.filters=io.flow.play.util.CorsWithLoggingFilter
play.filters.cors.allowedHttpMethods = ["GET", "POST", "PUT", "DELETE", "OPTIONS"]
This error handler capture client and server errors, always returning application/json. This handler also makes sure to log server error messages and assigns a unique error number that is returned to the user. This error number is also logged making it easy to find a particular error in the log.
Additionally, if flow environment is development, the actual contents of the exception will be returned (disabled in production to avoid leaking information).
play.http.errorHandler = "io.flow.play.util.ErrorHandler"
Anonymous Controller
-- Provides user(...) method to get an instance of the current user. -- (type: Option[User])
Identified Controller -- extends Anonymous -- requires a user to be present -- (type: User)
XXX RestController -- assumes basic authorization for the toke Default implementation uses user token through basic authorization
When splitting out background processing, it became apparent that we needed to have a way to send messages from an API service to actors running in the background processing jobs service.
With minimal amount of refactoring required, we can do this by binding a proxy actor to the original actor name in the API service, which send all messages it gets over SQS to a receiver in the jobs service. The receiver will forward all messages received on its SQS queue to the original actor that now lives in the jobs service.
To use this, you need to add the ActorProxyGuiceSupport
to your Actor guice module. Then you can bind your
proxy sender to the original actor name, where @Named("test-actor") actorRef: ActorRef
is used.
- bindActor[TestActor]("test-actor")
+ bindActorProxySender("test-actor", ReactiveActorProxySerde)
Then in your jobs service you can bind your original actor with a proxy receiver.
+ bindActor[TestActor]("test-actor")
+ bindActorProxyReceiver(
+ name = "test-actor-receiver",
+ proxiedName = "test-actor",
+ serde = ReactiveActorProxySerde
+ )
Once that is done, you can send messages as you normally would, as long as your ProxySerde
passed
to your sender and receiver, knows how to serialize and deserialize the messages.
class TestActorCaller @Inject() (@Named("test-actor") actor: ActorRef) extends Actor with ActorLogging {
override def receive: Receive = {
case Tick =>
// the following really send the message to the proxy we have bound to "test-actor"
actor ! ReactiveActor.Messages.Changed
}
}
class TestActor extends Actor with ActorLogging {
override def receive: Receive = {
case ReactiveActor.Messages.Changed => log.info("RECEIVED TEST ACTOR CHANGED MESSAGE!")
}
}
NOTE: The sender and receiver will use the service name and the proxied receiver actor name to create an SQS queue
