## Optionaler Datei-Upload

Sie können eine Datei optional machen, indem Sie Standard-Typannotationen verwenden und den Defaultwert auf `None` setzen:

	}
	funcname = f[0]
	pathAndLineNo := f[1]
	f = strings.Split(pathAndLineNo, ":")
	if runtime.GOOS == "windows" && len(f) == 3 {
		// Reattach drive letter.
		f = []string{f[0] + ":" + f[1], f[2]}

Zuerst einmal, Sie können `Path`-, `Query`- und Requestbody-Parameter-Deklarationen frei mischen und **FastAPI** wird wissen, was zu tun ist.

Und Sie können auch Body-Parameter als optional kennzeichnen, indem Sie den Defaultwert auf `None` setzen:

	}, name)

	if valid {

		// - letter/underscore followed by one or more letter/digit/underscore

            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));
        }

/files/{file_path:path}
```

In diesem Fall ist der Name des Parameters `file_path`. Der letzte Teil, `:path`, sagt aus, dass der Parameter ein *Pfad* sein soll.

Sie verwenden das also wie folgt:
