Hello, new to the forum.... I have a header being sent from the upstream server that looks like this:

x-authorization:Client="Web Client", Device="Chrome 47.0.2526.106", DeviceId="3a3591f34aa7bf0cbda943edb993dbf11ecf0f4e", Version="3.0.5805.0", UserId="1de587e5988kdsede6f60a4f50d545e0"

I need to grab the "UserId" value ONLY, and log it in the nginx access log in place of the normal $remote_user.

Some more info, I do not have access to change the upstream headers, otherwise i would just create a new userid header. This is what I have to work with.. :-)


Any help would be greatly appreciated.. I really have no clue how to even start on this one.. lol

Yea....... I know how to log a header... Please READ my post... its asking how do i log the SINGLE UserId value... This header contains multiple comma delimited values for the single header value "X-authorization" it contains a Client, Device, DeviceId, Version, AND UserId.. I only want to grab the UserId... Neither of those searches answers that question.

You asked "header being sent from the upstream server" and thats what those results show.
If you want to log a part of such value you could try a regex via 'map', or a regex via Lua but Lua can't write to normal nginx logfiles.
