logging using log4j with httpclient 5 beta ?

[Rémy Amouroux]

Hi All

I’m trying to use httpclient 5 beta to discuss to a http2 server through a proxy.

For the moment, my log4j configuration includes

log4j.logger.org.apache.hc.client5.http=DEBUG
log4j.logger.org.apache.hc.client5.http.wire=ERROR

while it allows me to see part of the communication between client and server, I don’t see the protocol negotiation.
Is there somewhere an explanation of the possible logging options for httpclient 5 ?

Regards

Hi Remy

HC 5 documentation is virtually non-existent at this point. I would
like to put some effort into it but I cannot commit to a particular
time line.

For now examples [1] and test code [2] is the best reference.

There is a log4j configuration template with some common logging
categories one can use as a starting point:

https://github.com/apache/httpcomponents-client/blob/master/httpclient5
-testing/src/test/resources/log4j2-debug.xml.template
