Das müssen Sie selbst in Ihrem Code tun und sicherstellen, dass Sie diese JSON-Schlüssel verwenden.

Es ist fast das Einzige, woran Sie denken müssen, es selbst richtigzumachen und die Spezifikationen einzuhalten.

Den Rest erledigt **FastAPI** für Sie.

///

## Die Abhängigkeiten aktualisieren { #update-the-dependencies }

Jetzt werden wir unsere Abhängigkeiten aktualisieren.

This is something that you have to do yourself in your code, and make sure you use those JSON keys.

It's almost the only thing that you have to remember to do correctly yourself, to be compliant with the specifications.

For the rest, **FastAPI** handles it for you.

///

## Update the dependencies { #update-the-dependencies }

Now we are going to update our dependencies.

We want to get the `current_user` *only* if this user is active.

	unformattedDisks := quorumUnformattedDisks(sErrs)
	if unformattedDisks && !firstDisk {
		return nil, errNotFirstDisk
	}

	// Return error when quorum unformatted disks but waiting for rest
	// of the servers to be online.
	if unformattedDisks && firstDisk {
		return nil, errFirstDiskWait
	}

	format, err = getFormatErasureInQuorum(formatConfigs)
	if err != nil {
		var drivesNotFound int

///

## Typen und Validierung { #types-and-validation }

Diese Umgebungsvariablen können nur **Textstrings** handhaben, da sie extern zu Python sind und kompatibel mit anderen Programmen und dem Rest des Systems (und sogar mit verschiedenen Betriebssystemen, wie Linux, Windows, macOS) sein müssen.

  /**

/// check

Notice that you don't have to create a special class and pass it somewhere to **FastAPI** to "register" it or anything similar.

You just pass it to `Depends` and **FastAPI** knows how to do the rest.

///

## Share `Annotated` dependencies { #share-annotated-dependencies }

In the examples above, you see that there's a tiny bit of **code duplication**.
