Platform Http Vertx

Since Camel 3.2

The camel-platform-http-vertx is a Vert.x based implementation of the PlatformHttp SPI.

Vert.x Route

This implementation will by default lookup an instance of VertxPlatformHttpRouter on the registry however you can configure an existing instance using the getter/setter on the VertxPlatformHttpEngine class.

Auto detection from classpath

To use this implementation all you need to do is to add the camel-platform-http-vertx dependency to the classpath, and the platform http component should auto-detect this.

Message Headers

Name Type Description

CamelVertxPlatformHttpAuthenticatedUser

io.vertx.ext.auth.User

If an authenticated user is present on the Vert.x Web RoutingContext, this header is populated with a User object containing the Principal.

CamelVertxPlatformHttpLocalAddress

io.vertx.core.net.SocketAddress

The local address for the connection if present on the Vert.x Web RoutingContext.

CamelVertxPlatformHttpRemoteAddress

io.vertx.core.net.SocketAddress

The remote address for the connection if present on the Vert.x Web RoutingContext.

Camel also populates all request.parameter and Camel also populates all request.parameter and request.headers. For example, given a client request with the URL, http://myserver/myserver?orderid=123, the exchange will contain a header named orderid with the value 123. request.headers. For example, given a client request with the URL, http://myserver/myserver?orderid=123, the exchange will contain a header named orderid with the value 123.

VertxPlatformHttpServer

In addition to the implementation of the PlatformHttp SPI based on Vert.x, this module provides a Vert.x based HTTP server compatible with the VertxPlatformHttpEngine: 

final int port = AvailablePortFinder.getNextAvailable();
final CamelContext context = new DefaultCamelContext();

VertxPlatformHttpServerConfiguration conf = new VertxPlatformHttpServerConfiguration();
conf.setBindPort(port);

context.addService(new VertxPlatformHttpServer(conf));
context.addRoutes(new RouteBuilder() {
    @Override
    public void configure() throws Exception {
        from("platform-http:/test")
            .routeId("get")
            .setBody().constant("Hello from Camel's PlatformHttp service");
    }
});

context.start();

Implementing a reverse proxy

Platform HTTP component can act as a reverse proxy, in that case Exchange.HTTP_URI, Exchange.HTTP_HOST headers are populated from the absolute URL received on the request line of the HTTP request.

Here’s an example of a HTTP proxy that simply redirects the Exchange to the origin server.

from("platform-http:proxy")
    .toD("http://"
        + "${headers." + Exchange.HTTP_HOST + "}");
