Method Detail

messageReceived

public void messageReceived(io.netty.channel.ChannelHandlerContext ctx,
                            io.netty.handler.codec.http.FullHttpRequest request)
                     throws Exception

Specified by:

messageReceived in class io.netty.channel.SimpleChannelInboundHandler<io.netty.handler.codec.http.FullHttpRequest>

Throws:

Exception

respond

public abstract void respond(io.netty.channel.ChannelHandlerContext ctx,
                             io.netty.handler.codec.http.FullHttpRequest request)
                      throws Exception

Allows concrete subclasses to very how they will respond after a message has been sent to the target SockJS service. Different transport protocols require different responses, for example jsonp_send requires an OK response while xhr_send NO_CONTENT.

Parameters:

ctx - the current ChannelHandlerContext.

request - the http request.

Throws:

Exception - if a failure occurs while trying to respond.

respond

protected void respond(io.netty.channel.ChannelHandlerContext ctx,
                       io.netty.handler.codec.http.HttpVersion httpVersion,
                       io.netty.handler.codec.http.HttpResponseStatus status,
                       String message)
