All Implemented Interfaces:

public class ClientRequestResponseConverter
extends io.netty.channel.ChannelDuplexHandler

A channel handler for HttpClient to convert netty's http request/response objects to HttpClient's request/response objects. It handles the following message types:

Reading Objects

• HttpResponse: Converts it to HttpClientResponse
• HttpContent: Converts it to the content of the previously generated HttpClientResponse
• FullHttpResponse: Converts it to a HttpClientResponse with pre-populated content observable.
• Any other object: Assumes that it is a transformed HTTP content & pass it through to the content observable.

Writing Objects

• HttpClientRequest: Converts it to a HttpRequest
• ByteBuf to an HttpContent
• Pass through any other message type.

Field Detail

KEEP_ALIVE_TIMEOUT_MILLIS_ATTR

public static final io.netty.util.AttributeKey<java.lang.Long> KEEP_ALIVE_TIMEOUT_MILLIS_ATTR

This attribute stores the value of any dynamic idle timeout value sent via an HTTP keep alive header. This follows the proposal specified here: http://tools.ietf.org/id/draft-thomson-hybi-http-timeout-01.html The attribute can be extracted from an HTTP response header using the helper method HttpClientResponse.getKeepAliveTimeoutSeconds()

DISCARD_CONNECTION

public static final io.netty.util.AttributeKey<java.lang.Boolean> DISCARD_CONNECTION

CONN_CLOSE_BEFORE_RESPONSE

public static final java.io.IOException CONN_CLOSE_BEFORE_RESPONSE
