How to capture X-Forwarded-For (tRestRequest)

root — Sat, 16 Nov 2024 09:59:46 GMT

Hi, I am using tRestRequest. I want to capture " X-Forwarded-For" parameter from the header of the incoming message.
When I am adding that parameter in tRestRequest, it does not allow me to do that. Please advise. Thank you.

In meantime check request context properties such as "ALL_HEADER_PARAMS" and "ALL_QUERY_PARAMS"
thanks, Sergey

yes, indeed!
thanks for the hint, Sergey!
forgot I already answered such question (even several times ).
so please try following way to retrieve the header in tJavaRow or tJavaFlex component right after tRESTRequest component:

((javax.ws.rs.core.MultivaluedMap<String, String>) ((java.util.Map<String, Object>) globalMap.get("restRequest")).get("ALL_HEADER_PARAMS")).getFirst("X-Forwarded-For")

It could be really helpful if Talend has some facade pattern for this king of access either like:
InboundContext.getHeaders.getXForwardFor()
or
InboundContext.getHeaders.get("Name")
I love the tree metadata information of the inbound and outbound contexts for example in Oracle Service Bus, here in Talend it is not that well organized and easily accessible.

headers map can be easily exposed using component variables regular way in Studio.
(actually message context also - as more generic way)
