quarkus(vertx) how to get request body in a blocking way

Question

What I've tried:

inject CurrentVertxRequest context and then get body from there

@Path("/map_event")
public class MapEventApi {

    @Inject
    CurrentVertxRequest reqContext;
  

    @POST
    @Consumes({ "application/json" })
    @Produces({ "application/json" })
    Response create(@Valid MapEvent mapEvent, @Context SecurityContext securityContext) throws Exception {
        String body = reqContext.getCurrent().getBodyAsString();
        ...
    }

}

but this will give a warning:

2022-01-25 18:22:08,854 WARN  [null:-1] (executor-thread-0) BodyHandler in not enabled on this route: RoutingContext.getBodyAsString(...) in always be NULL

another try:

inject standard JaxRS HttpServletRequest context

@Context HttpServletRequest

will get this error:

org.jboss.resteasy.spi.LoggableFailure: RESTEASY003880: Unable to find contextual data of type: javax.servlet.http.HttpServletRequest
        at org.jboss.resteasy.core.ContextParameterInjector$GenericDelegatingProxy.invoke(ContextParameterInjector.java:155)
        at com.sun.proxy.$Proxy97.getInputStream(Unknown Source)

I guess it's because quarkus use vertx under the hood so injecting regular jaxrs context won't work since it's not the same thread.

@geoand want to read the body as string, and do some further process — Ziqi Liu, Jan 27 '22 at 18:57
Did you try adding `String body` as a parameter of `create`? — geoand, Jan 28 '22 at 07:28
@geoand actually the `MapEvent mapEvent` parameter capture the body, converted by jackson automatically. But I still want to examine the raw body in the interceptor for logging purpose — Ziqi Liu, Jan 29 '22 at 18:22
The body is only read once. If you need the raw form, I suggest using that as method parameter and then do the mapping manually in the method body — geoand, Jan 31 '22 at 07:29

According to @geoand proposiiton following solution worked for me:

@POST
@Consumes(MediaType.TEXT_PLAIN)
@Produces(MediaType.APPLICATION_JSON)
Response create(String body) throws Exception {
    ...
}

consuming the request as String was the trick → @Consumes(MediaType.TEXT_PLAIN)
