Camel HTTP/2 support

Hi folks,

How can I use Camel to send HTTP/2 requests to an existing HTTP/2 endpoint?

I tried out the http-component and it does not seem to support http/2.
Are there any other camel components available that support that? Are there any plans to extend the http-component with http/2 support?
What other alternatives are there?

Thanks in advance,
   Alphonse

Thanks,

I had already tried out the http component. Now I also tried out netty, undertow and vert.x http. All of them don’t seem to support http/2.
Looks like the rest component just uses the mentioned components.

So i will go with the custom processor for now.

Camel provides various HTTP clients like:

1. http (https://camel.apache.org/components/4.0.x/http-component.html)
2. netty http (
https://camel.apache.org/components/4.0.x/netty-http-component.html)
3. vert.x http (
https://camel.apache.org/components/4.0.x/vertx-http-component.html)
4. rest (https://camel.apache.org/components/4.0.x/rest-component.html)

I don't know if any of those client explicitly support HTTP/2, but if not,
you can make a custom processor:

https://camel.apache.org/manual/processor.html

And then run a http request (*java.net.http.HttpRequest*) like this:

HttpRequest request = HttpRequest.newBuilder()
  .uri(new URI("https://postman-echo.com/get"))
  .version(HttpClient.Version.HTTP_2)
  .GET()
  .build();

In the HTTP client since JDK 11 you can explicitly set the version.
