Package org.apache.camel.http.common

Interface HttpBinding

All Known Implementing Classes:
DefaultHttpBinding
public interface HttpBinding
A pluggable strategy for configuring the http binding so reading request and writing response can be customized using the Java Servlet API.

This is also used by the camel-jetty component in the JettyHttpConsumer class.

    • isUseReaderForPayload

      boolean isUseReaderForPayload()
      Should reader by used instead of input stream.
      Returns:
      true if reader should be used
      See Also:

    • setUseReaderForPayload

      void setUseReaderForPayload(boolean useReaderForPayload)
      Should the ServletRequest.getReader() be exposed as the payload of input messages in the Camel Message.getBody() or not. If false then the ServletRequest.getInputStream() will be exposed.

      This is by default turned off. If you enable this then be aware that Java will deserialize the incoming data from the request to Java and that can be a potential security risk.
