I am using nginx upload module for uplaoding files to server. But I wanted nginx to upload to different paths, not to a path mentioned in upload_store. So I am taking help of nginx-lua module to change the upload_store value on each request like below.


location /umtest {
upload_pass /nginx_response;
set $upload_store '';
rewrite_by_lua '
local header = ngx.req.raw_header()
ngx.say("type header",header)
dst_path_dir = ngx.req.get_headers()["Dst-Dir"]
ngx.say("dst_path_dir",dst_path_dir)
ngx.var.upload_store = dst_path_dir
ngx.say("upload store path" ,ngx.var.upload_store)
';
upload_set_form_field $upload_field_name.name
"$upload_file_name";
upload_set_form_field $upload_field_name.content_type
"$upload_content_type";
upload_set_form_field $upload_field_name.path
"$upload_tmp_path"
upload_cleanup 400 404 499 500-505;
}


Now when I POST to the '/umtest' it will change the upload_store value, but it will not execute the nginx upload direcives (i.e., upload will not happen). When I comment the rewrite_by_lua directive , the upload happens. My question is cant we use both at a same time to achieve the purpose?_______________________________________________
