Кажется, что из коробки ngx_http_core_module должен регистрировать request_body, если он является частью log_format.
Однако я не вижу, чтобы это работало ни для чего, что включает auth_request в location блок. Я не совсем уверен, чем это вызвано. Кажется, он отлично работает для блоков location, которые не включают директиву auth_request.
Типичный сгенерированный блок местоположения будет выглядеть следующим образом:
server {
server_name test-api.dummy.co ;
listen 80 ;
listen 443 ssl http2 ;
set $proxy_upstream_name "-";
ssl_certificate_by_lua_block {
certificate.call()

set $namespace "control";
set $ingress_name "apps-public-gateway-api-ig-auth";
set $service_name "istio-ingressgateway";
set $service_port "80";
set $location_path "/api/v2/management/customer/[a-zA-Z0-9-]+/";

}

Возможно ли это с помощью Lua сценарий, возможно, если мы не сможем добиться этого из коробки?
А как go о регистрации тела ответа без специального шаблона для ingress-nginx контроллера?
Заранее спасибо .
