Change HTTP method of Sub request

Server NGINX
1

I have a Rails app that receives a POST and I would like to
X-Accel-Redirect a file back to the client, but the fileserver is
receiving a POST. Can I rewrite the HTTP method internally? I cannot
find the documentation on this.

How about this?

location /proxy {
      set_unescape_uri $body $arg_body;
      echo_subrequest_async POST /fileserver -b $body
 }

Then X-Accel-Redirect to /proxy?body=xxxx where xxxx is the content
body that you have read from within your PHP script.

Good luck :slight_smile:

Forgot to mention that set_unescape_uri is provided by the
ngx_set_misc module below:

http://github.com/agentzh/set-misc-nginx-module

and echo_subrequest_async is provided by the ngx_echo module:

location /storage/ {
    proxy_pass http://storage-backend...;
    proxy_pass_method GET;
    proxy_pass_request_body off;
    proxy_set_header Content-Length "";
}

proxy_pass_method does not exist in the 0.7 or 0.8 branches. There is
proxy_method but I believe it simply allows more than the standard 4
verbs to be proxied
(Module ngx_http_proxy_module).

Yes, I was too lazy to recheck exact name.

No, it sets method to be used in request to backend server.
