subRequest to a named location

[vigie]

Hi

I'd like my njs function to manipulate the req body and then send it along to a private location that is not exposed in the conf file as a public location. I tried

req.subrequest('@myNamedLocation', ...

and

req.subrequest('http://my.private.url', ...

but in both cases nginx looked in the html folder for a file with these names.

Please advise on how I can best achieve this use case.

Thanks,
Matt

Hi @vigie,

Unfortunately it is not possible to make a subrequest to a named location due to limitation of the nginx internal API. But you can make a subrequest to an internal location which is protected from the outside. Please, take a look: http://nginx.org/en/docs/http/ngx_http_core_module.html#internal

for example:

var my_body = process(req.body);
req.subrequest('/internal', {body:my_body}, 
                           function(reply) {res.return(reply.status == 200 ? 200 : 500)})

This is exactly what I was looking for, internal had escaped me somehow.

Thanks very much for the quick help @xeioex
