How to log request body instead of <multipart>?

[mrados7]

I need to log my request body, but it keeps printing . Body form is "form-data".

The default RawRequestFilter delegates to the default BodyReplacer which in turn replaces multi part bodies with the string <multi-part>. If you need to override the default behaviour you need to configure your own RawRequestFilter.

Can you give me an example how to make @bean RawRequestFilter cause I'm not sure how to use replaceBody when I need to save that body not replace it with some string. I'm using logbook-spring-boot-starter.

That should do the trick.

@Bean
public RawRequestFilter rawRequestFilter() {
    return RawRequestFilter.none();
}

Yeah, that's first thing I tried but it shows nothing in log form body.

I only read multipart, nothing about form. Ok, I guess you're using the LogbookFilter as part of your filter chain. You're most likely hitting this: https://github.com/zalando/logbook#servlet

The LogbookFilter will, by default, treat requests with a application/x-www-form-urlencoded body not different from any other request, i.e you will see the request body in the logs. The downside of this approach is that you won't be able to use any of the HttpServletRequest.getParameter*(..) methods. See issue #94 for some more details.

As of Logbook 1.5.0, you can now specify one of three strategies that define how Logbook deals with this situation by using the logbook.servlet.form-request system property:

Value	Pros	Cons
body(default)	Body is logged	Downstream code can not use getParameter*()
parameter	Body is logged (but it's reconstructed from parameters)	Downstream code can not use getInputStream()
off	Downstream code can decide whether to use getInputStream() or getParameter*()	Body is not logged

Ok thank you, understood :)
