  7. def cachedHostConnectionPool[T](host: String, port: Int = 80, settings: ConnectionPoolSettings = defaultConnectionPoolSettings, log: LoggingAdapter = system.log): Flow[(HttpRequest, T), (Try[HttpResponse], T), HostConnectionPool]

    Returns a akka.stream.scaladsl.Flow which dispatches incoming HTTP requests to the per-ActorSystem pool of outgoing HTTP connections to the given target host endpoint.

    Returns a akka.stream.scaladsl.Flow which dispatches incoming HTTP requests to the per-ActorSystem pool of outgoing HTTP connections to the given target host endpoint. For every ActorSystem, target host and pool configuration a separate connection pool is maintained. The HTTP layer transparently manages idle shutdown and restarting of connections pools as configured. The returned akka.stream.scaladsl.Flow instances therefore remain valid throughout the lifetime of the application.

    The internal caching logic guarantees that there will never be more than a single pool running for the given target host endpoint and configuration (in this ActorSystem).

    Since the underlying transport usually comprises more than a single connection the produced flow might generate responses in an order that doesn't directly match the consumed requests. For example, if two requests A and B enter the flow in that order the response for B might be produced before the response for A. In order to allow for easy response-to-request association the flow takes in a custom, opaque context object of type T from the application which is emitted together with the corresponding response.

    To configure additional settings for the pool (and requests made using it), use the akka.http.host-connection-pool config section or pass in a ConnectionPoolSettings explicitly.

    Same as #cachedHostConnectionPool but for encrypted (HTTPS) connections.

    Starts a new connection pool to the given host and configuration and returns a akka.stream.scaladsl.Flow which dispatches the requests from all its materializations across this pool.

    Starts a new connection pool to the given host and configuration and returns a akka.stream.scaladsl.Flow which dispatches the requests from all its materializations across this pool. While the started host connection pool internally shuts itself down automatically after the configured idle timeout it will spin itself up again if more requests arrive from an existing or a new client flow materialization. The returned flow therefore remains usable for the full lifetime of the application.

    Since the underlying transport usually comprises more than a single connection the produced flow might generate responses in an order that doesn't directly match the consumed requests. For example, if two requests A and B enter the flow in that order the response for B might be produced before the response for A. In order to allow for easy response-to-request association the flow takes in a custom, opaque context object of type T from the application which is emitted together with the corresponding response.

    Constructs a akka.http.scaladsl.Http.ServerLayer stage using the given akka.http.scaladsl.settings.ServerSettings. The returned akka.stream.scaladsl.BidiFlow isn't reusable and can only be materialized once. The remoteAddress, if provided, will be added as a header to each akka.http.scaladsl.model.HttpRequest this layer produces if the akka.http.server.remote-address-header configuration option is enabled.

  33. def setDefaultClientHttpsContext(context: HttpsConnectionContext): Unit

  34. def shutdownAllConnectionPools(): Future[Unit]

    Triggers an orderly shutdown of all host connections pools currently maintained by the akka.actor.ActorSystem.

    Triggers an orderly shutdown of all host connections pools currently maintained by the akka.actor.ActorSystem. The returned future is completed when all pools that were live at the time of this method call have completed their shutdown process.

    If existing pool client flows are re-used or new ones materialized concurrently with or after this method call the respective connection pools will be restarted and not contribute to the returned future.

  35. def singleRequest(request: HttpRequest, connectionContext: HttpsConnectionContext = defaultClientHttpsContext, settings: ConnectionPoolSettings = defaultConnectionPoolSettings, log: LoggingAdapter = system.log): Future[HttpResponse]

    Fires a single akka.http.scaladsl.model.HttpRequest across the (cached) host connection pool for the request's effective URI to produce a response future.

    Fires a single akka.http.scaladsl.model.HttpRequest across the (cached) host connection pool for the request's effective URI to produce a response future.

    If an explicit ConnectionContext is given then it rather than the configured default ConnectionContext will be used for setting up the HTTPS connection pool, if the request is targeted towards an https endpoint.

    Note that the request must have an absolute URI, otherwise the future will be completed with an error.

  36. def singleWebSocketRequest[T](request: WebSocketRequest, clientFlow: Flow[Message, Message, T], connectionContext: ConnectionContext = defaultClientHttpsContext, localAddress: Option[InetSocketAddress] = None, settings: ClientConnectionSettings = ClientConnectionSettings(system), log: LoggingAdapter = system.log)(implicit mat: Materializer): (Future[WebSocketUpgradeResponse], T)

    Runs a single WebSocket conversation given a Uri and a flow that represents the client side of the WebSocket conversation.

  37. def superPool[T](connectionContext: HttpsConnectionContext = defaultClientHttpsContext, settings: ConnectionPoolSettings = defaultConnectionPoolSettings, log: LoggingAdapter = system.log): Flow[(HttpRequest, T), (Try[HttpResponse], T), NotUsed]

    Creates a new "super connection pool flow", which routes incoming requests to a (cached) host connection pool depending on their respective effective URIs.

    Creates a new "super connection pool flow", which routes incoming requests to a (cached) host connection pool depending on their respective effective URIs. Note that incoming requests must have an absolute URI.

    If an explicit ConnectionContext is given then it rather than the configured default ConnectionContext will be used for setting up HTTPS connection pools, if required.

    Since the underlying transport usually comprises more than a single connection the produced flow might generate responses in an order that doesn't directly match the consumed requests. For example, if two requests A and B enter the flow in that order the response for B might be produced before the response for A. In order to allow for easy response-to-request association the flow takes in a custom, opaque context object of type T from the application which is emitted together with the corresponding response.

  1. def bind(interface: String, port: Int = DefaultPortForProtocol, connectionContext: ConnectionContext = defaultServerHttpContext, settings: ServerSettings = ServerSettings(system), log: LoggingAdapter = system.log): Source[IncomingConnection, Future[ServerBinding]]

    Creates a akka.stream.scaladsl.Source of akka.http.scaladsl.Http.IncomingConnection instances which represents a prospective HTTP server binding on the given endpoint.

    Creates a akka.stream.scaladsl.Source of akka.http.scaladsl.Http.IncomingConnection instances which represents a prospective HTTP server binding on the given endpoint.

    If the given port is 0 the resulting source can be materialized several times. Each materialization will then be assigned a new local port by the operating system, which can then be retrieved by the materialized akka.http.scaladsl.Http.ServerBinding.

    If the given port is non-zero subsequent materialization attempts of the produced source will immediately fail, unless the first materialization has already been unbound. Unbinding can be triggered via the materialized akka.http.scaladsl.Http.ServerBinding.

    If an ConnectionContext is given it will be used for setting up TLS encryption on the binding. Otherwise the binding will be unencrypted.

    If no port is explicitly given (or the port value is negative) the protocol's default port will be used, which is 80 for HTTP and 443 for HTTPS.

    Parameter parallelism specifies how many requests are attempted to be handled concurrently per connection. In HTTP/1 this makes only sense if HTTP pipelining is enabled (which is not recommended). The default value of 0 means that the value is taken from the akka.http.server.pipelining-limit setting from the configuration. In HTTP/2, the default value is taken from akka.http.server.http2.max-concurrent-streams.

    Any other value for parallelism overrides the setting.
