  • Method Details

    • contentLengthOption

      scala.Option<Object> contentLengthOption()
      Description copied from interface: HttpEntity
      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.

      Specified by:
      contentLengthOption in interface HttpEntity
      Returns:
      (undocumented)

    • contentType

      ContentType contentType()
      Description copied from interface: HttpEntity
      The ContentType associated with this entity.
      Specified by:
      contentType in interface HttpEntity
      Returns:
      (undocumented)

    • data

      akka.stream.scaladsl.Source<akka.util.ByteString,Object> data()

    • dataBytes

      akka.stream.scaladsl.Source<akka.util.ByteString,Object> dataBytes()
      Description copied from interface: HttpEntity
      A stream of the data of this entity.
      Specified by:
      dataBytes in interface HttpEntity
      Returns:
      (undocumented)

    • isKnownEmpty

      boolean isKnownEmpty()
      Description copied from interface: HttpEntity
      Determines whether this entity is known to be empty.
      Specified by:
      isKnownEmpty in interface HttpEntity
      Specified by:
      isKnownEmpty in interface HttpEntity
      Returns:
      (undocumented)

    • transformDataBytes

      HttpEntity.WithoutKnownLength transformDataBytes(akka.stream.scaladsl.Flow<akka.util.ByteString,akka.util.ByteString,Object> transformer)
      Description copied from interface: HttpEntity
      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.

      Specified by:
      transformDataBytes in interface HttpEntity
      Parameters:
      transformer - (undocumented)
      Returns:
      (undocumented)

    • withData

      HttpEntity.WithoutKnownLength withData(akka.stream.scaladsl.Source<akka.util.ByteString,Object> data)

    • withSizeLimit

      HttpEntity.WithoutKnownLength withSizeLimit(long maxBytes)
      Description copied from interface: HttpEntity
      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.

      Specified by:
      withSizeLimit in interface HttpEntity
      Specified by:
      withSizeLimit in interface HttpEntity
      Parameters:
      maxBytes - (undocumented)
      Returns:
      (undocumented)

    • withoutSizeLimit

      HttpEntity.WithoutKnownLength withoutSizeLimit()
      Description copied from interface: HttpEntity
      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 HttpEntity.withSizeLimit(long) for more details.
