Of course, you will probably find much better ways to take advantage of this than formatting JSON. 😉

### `orjson` or Response Model { #orjson-or-response-model }

If what you are looking for is performance, you are probably better off using a [Response Model](../tutorial/response-model.md) than an `orjson` response.

            linkElement.appendChild(classNameElement);
            return linkElement;
        }

        //this if is a bit cheesy but 1-letter classname surely means a generic type and the warning will be useless
        if (className.length() > 1) {
            listener.warning(String.format("Could not generate link for unknown class '%s'", className));
        }

  if [[ -z "${im_cmd}" ]] ; then
    echo "ImageMagick (convert or magick) does not exist."
    exit 1
  fi
  target_file=$(echo "$url" | sed -e "s#^file:/*#/#g")
  # Build format hint from MIME type for better ImageMagick compatibility
  format_hint=""
  case "${mimetype}" in
    "image/gif")  format_hint="gif:" ;;
    "image/tiff") format_hint="tiff:" ;;
    "image/png")  format_hint="png:" ;;

Wenn Sie Clients unterstützen müssen, die keinen `Content-Type`-Header senden, können Sie die strikte Prüfung deaktivieren, indem Sie `strict_content_type=False` setzen:

{* ../../docs_src/strict_content_type/tutorial001_py310.py hl[4] *}

Mit dieser Einstellung werden Requests ohne `Content-Type`-Header im Body als JSON geparst. Das entspricht dem Verhalten älterer FastAPI-Versionen.

FastAPI kann sie in jedem Fall überschreiben.

///

Anschließend können Sie Ihre Überschreibungen zurücksetzen (entfernen), indem Sie `app.dependency_overrides` auf ein leeres `dict` setzen:

```Python
app.dependency_overrides = {}
```


/// tip | Tipp

{* ../../docs_src/header_param_models/tutorial003_an_py310.py hl[19] *}

/// warning | Achtung

Bevor Sie `convert_underscores` auf `False` setzen, bedenken Sie, dass einige HTTP-Proxies und -Server die Verwendung von Headern mit Unterstrichen nicht zulassen.
