These proxies could handle HTTPS certificates and other things.

## Proxy Forwarded Headers { #proxy-forwarded-headers }

A **proxy** in front of your application would normally set some headers on the fly before sending the requests to your **server** to let the server know that the request was **forwarded** by the proxy, letting it know the original (public) URL, including the domain, that it is using HTTPS, etc.

### Erforderlich, kann `None` sein

Sie können deklarieren, dass ein Parameter `None` akzeptiert, aber dennoch erforderlich ist. Das zwingt Clients, den Wert zu senden, selbst wenn er `None` ist.

Um das zu machen, deklarieren Sie, dass `None` ein gültiger Typ ist, aber verwenden Sie dennoch `...` als Default:

{* ../../docs_src/query_params_str_validations/tutorial006c_an_py310.py hl[9] *}

            try {
                CommonServerMessageBlockResponse resp = thisReq.getResponse();
                if (log.isTraceEnabled()) {
                    log.trace("Sending " + thisReq);
                }
                resp = super.sendrecv(curHead, resp, params);

                if (!checkStatus(curHead, resp)) {
                    if (log.isDebugEnabled()) {

Wenn Sie zum Beispiel Modelle mit vielen optionalen Attributen in einer NoSQL-Datenbank haben, und Sie möchten nicht ellenlange JSON-Responses voller Defaultwerte senden.

### Den `response_model_exclude_unset`-Parameter verwenden

Sie können den *Pfadoperation-Dekorator*-Parameter `response_model_exclude_unset=True` setzen:

/**
 * This class simplifies communication for protocols that support
 * multiplexing requests. It encapsulates a stream and some protocol

you had a client that was sending an invalid Content-Type or Accept header to
the API, in 1.2 you will either receive a 415 or 406 error.
The only client
this is known to affect is curl when you use -d with JSON but don't set a
content type, helpfully sends "application/x-www-urlencoded", which is not
correct.
Other client authors should double check that you are sending proper
