Example 1 with RouterResponseHandler

use of org.webpieces.router.api.RouterResponseHandler in project webpieces by deanhiller.

the class WebpiecesStreamHandle method incomingRequest.

@Override
public StreamRef incomingRequest(Http2Request headers, ResponseStream stream) {
    RouterResponseHandler handler = new RouterResponseHandlerImpl(stream);
    StreamRef ref = routingService.incomingRequest(headers, handler);
    return ref;
}

Example 2 with RouterResponseHandler

use of org.webpieces.router.api.RouterResponseHandler in project webpieces by deanhiller.

the class RouterServiceImpl method incomingRequest.

@Override
public StreamRef incomingRequest(Http2Request req, RouterResponseHandler handler) {
    // ******************************************************************************************
    // DO NOT ADD CODE HERE OR ABOVE THIS METHOD in RouterService.  This is our CATCH-ALL point so
    // ANY code above that is not protected from our catch and respond to clients
    // ******************************************************************************************
    String txId = generate();
    // I do NOT like doing Guice creation on the request path(Dagger creation would probably be ok) BUT this
    // is very worth it AND customers can swap out these critical classes if they need to quickly temporarily fix a bug while
    // we work on the bug.  We can easily give customers bug fixes like add binder.bind(ClassWithBug.class).to(BugFixCode.class)
    ProxyStreamHandle proxyHandler = proxyProvider.get();
    proxyHandler.init(handler, req);
    MDC.put("txId", txId);
    // top level handler...
    try {
        RouterStreamRef streamRef = incomingRequestProtected(req, proxyHandler);
        XFuture<StreamWriter> writer = streamRef.getWriter().thenApply(w -> new TxStreamWriter(txId, w));
        XFuture<StreamWriter> finalWriter = writer.handle((r, t) -> {
            if (t == null)
                return XFuture.completedFuture(r);
            XFuture<StreamWriter> fut = proxyHandler.topLevelFailure(req, t);
            return fut;
        }).thenCompose(Function.identity());
        return new RouterStreamRef("routerSevcTop", finalWriter, streamRef);
