Abstract Value Members

  1. abstract def contentLengthOption: Option[Long]

    Some(content length) if a length is defined for this entity, None otherwise.

    Some(content length) if a length is defined for this entity, None otherwise. A length is only defined for Strict and Default entity types.

    In many cases it's dangerous to rely on the (non-)existence of a content-length. HTTP intermediaries like (transparent) proxies are allowed to change the transfer-encoding which can result in the entity being delivered as another type as expected.

  2. abstract def contentType: ContentType

  5. abstract def transformDataBytes(transformer: Flow[ByteString, ByteString, Any]): HttpEntity

    Returns a copy of the given entity with the ByteString chunks of this entity transformed by the given transformer.

    Returns a copy of the given entity with the ByteString chunks of this entity transformed by the given transformer. For a Chunked entity, the chunks will be transformed one by one keeping the chunk metadata (but may introduce an extra chunk before the LastChunk if transformer.onTermination returns additional data).

    This method may only throw an exception if the transformer function throws an exception while creating the transformer. Any other errors are reported through the new entity data stream.

  6. abstract def withContentType(contentType: ContentType): BodyPartEntity

    Creates a copy of this HttpEntity with the contentType overridden with the given one.

    Creates a copy of this HttpEntity with the contentType overridden with the given one.

  7. abstract def withSizeLimit(maxBytes: Long): BodyPartEntity

    Apply the given size limit to this entity by returning a new entity instance which automatically verifies that the data stream encapsulated by this instance produces at most maxBytes data bytes.

    Apply the given size limit to this entity by returning a new entity instance which automatically verifies that the data stream encapsulated by this instance produces at most maxBytes data bytes. In case this verification fails the respective stream will be terminated with an EntityStreamException either directly at materialization time (if the Content-Length is known) or whenever more data bytes than allowed have been read.

    When called on Strict entities the method will return the entity itself if the length is within the bound, otherwise a Default entity with a single element data stream. This allows for potential refinement of the entity size limit at a later point (before materialization of the data stream).

    By default all message entities produced by the HTTP layer automatically carry the limit that is defined in the application's max-content-length config setting. If the entity is transformed in a way that changes the Content-Length and then another limit is applied then this new limit will be evaluated against the new Content-Length. If the entity is transformed in a way that changes the Content-Length and no new limit is applied then the previous limit will be applied against the previous Content-Length.

  8. abstract def withoutSizeLimit(): BodyPartEntity

    Lift the size limit from this entity by returning a new entity instance which skips the size verification.

    Lift the size limit from this entity by returning a new entity instance which skips the size verification.

    By default all message entities produced by the HTTP layer automatically carry the limit that is defined in the application's max-content-length config setting. It is recommended to always keep an upper limit on accepted entities to avoid potential attackers flooding you with too large requests/responses, so use this method with caution.

    See withSizeLimit for more details.

  2. def discardBytes(mat: Materializer): DiscardedEntity

    Discards the entities data bytes by running the dataBytes Source contained in this entity.

    Discards the entities data bytes by running the dataBytes Source contained in this entity.

    Note: It is crucial that entities are either discarded, or consumed by running the underlying akka.stream.scaladsl.Source as otherwise the lack of consuming of the data will trigger back-pressure to the underlying TCP connection (as designed), however possibly leading to an idle-timeout that will close the connection, instead of just having ignored the data.

    Warning: It is not allowed to discard and/or consume the entity.dataBytes more than once as the stream is directly attached to the "live" incoming data source from the underlying TCP connection. Allowing it to be consumable twice would require buffering the incoming data, thus defeating the purpose of its streaming nature. If the dataBytes source is materialized a second time, it will fail with an "stream can cannot be materialized more than once" exception.

    When called on Strict entities or sources whose values can be buffered in memory, the above warnings can be ignored. Repeated materialization is not necessary in this case, avoiding the mentioned exceptions due to the data being held in memory.

    In future versions, more automatic ways to warn or resolve these situations may be introduced, see issue #18716.

    Collects all possible parts and returns a potentially future Strict entity for easier processing. The Future is failed with an TimeoutException if the stream isn't completed after the given timeout, or with a EntityStreamException when the end of the entity is not reached within the maximum number of bytes as configured in akka.http.parsing.max-to-strict-bytes. Not that this method does not support different defaults for client- and server use: if you want that, use the toStrict method and pass in an explicit maximum number of bytes.
