The following works for me:


location ~ upload$ {
# Pass altered request body to this location
upload_pass @after_upload;

# Store files to this directory
upload_store /www/media/tmp;

# Set specified fields in request body
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";

# Inform backend about hash and size of a file
upload_aggregate_form_field "${upload_field_name}_md5"
"$upload_file_md5";
upload_aggregate_form_field "${upload_field_name}_size"
"$upload_file_size";

upload_pass_form_field "_xsrf";

upload_cleanup 400 404 499 500-505;
}

location @after_upload {
proxy_pass http://frontends;
}

location / {
proxy_pass_header Server;
proxy_pass http://frontends;
}


And in Tornado:

@tornado.web.authenticated
def post(self, uid):

# pull in details created by the nginx file upload module
fname = self.get_argument('imagefile_name', None)
content_type = self.get_argument('imagefile_content_type', None)
file_size = self.get_argument('imagefile_size', -1)
file_hash = self.get_argument('imagefile_md5', '')
tmp_path = self.get_argument('imagefile_path', None)

if tmp_path is not None:
logging.info("::::FILE UPLOAD::::")
logging.info("FILE NAME: %s" % fname)
logging.info("FILE TYPE: %s" % content_type)
logging.info("FILE TMP PATH: %s" % tmp_path)

dest_dir = "/www/%s" % addressid
if not os.path.exists(dest_dir):
makedirs(dest_dir)

# move the file into place

fname = '.'.join(map(slugify, os.path.splitext(fname)))
dest_path = '%s/%s' % (dest_dir, fname)
logging.info("FILE ACTUAL PATH: %s" % dest_path)
move(tmp_path, dest_path)
