uwsgi not honoring request method in nginx subrequest

[amotl]

Hey there,

while switching our Python WSGI Pyramid application stack
to uWSGI behind OpenResty we hit a road block when issuing
subrequests from Lua to the uWSGI application.

The code in ngx_http_uwsgi_module.c does not seem to honor
the request method when being in the context of a subrequest.
Instead, it seems to inherit the request method of the origin
request.

We're using OpenResty 1.2.6.6 (Nginx 1.2.6), however switching
to OpenResty 1.2.7.5 (Nginx 1.2.7) makes no difference.

We filed this issue to nginx core as well [1] since the module ngx_http_uwsgi_module.c seems to be maintained there, but nevertheless we wanted to notice you as well.

We prepared a wash & go buildout environment and a summary to reproduce this issue:

• https://github.com/amotl/openresty-uwsgi-buildout/
• https://github.com/amotl/openresty-uwsgi-buildout/blob/master/doc/uwsgi-subrequest-issue.rst

Thanks for looking into this!

Cheers,
Andreas.

The solution to this issue is quite easy by simply doing:

uwsgi_param REQUEST_METHOD $echo_request_method;
