/// tip | "Tipp"

Beachten Sie, dass wir in diesem Fall eine Standard-Python-Funktion `open()` verwenden, die mit einer Datei interagiert.

Es handelt sich also um I/O (Input/Output), welches „Warten“ erfordert, bis Dinge auf die Festplatte geschrieben werden.

Aber `open()` verwendet nicht `async` und `await`.

Daher deklarieren wir die Eventhandler-Funktion mit Standard-`def` statt mit `async def`.

# GraphQL

As **FastAPI** is based on the **ASGI** standard, it's very easy to integrate any **GraphQL** library also compatible with ASGI.

You can combine normal FastAPI *path operations* with GraphQL on the same application.

/// tip

**GraphQL** solves some very specific use cases.

It has **advantages** and **disadvantages** when compared to common **web APIs**.

		APICode: "kms:NotSupported",
		Err:     "requested functionality is not supported",
	}
)

// Error is a KMS error that can be translated into an S3 API error.
//
// It does not implement the standard error Unwrap interface for
// better error log messages.
type Error struct {
	Code    int    // The HTTP status code returned to the client
	APICode string // The API error code identifying the error

		"Invalid storage class value",
		"Please check the value",
		`MINIO_STORAGE_CLASS_STANDARD: Format "EC:<Default_Parity_Standard_Class>" (e.g. "EC:3"). This sets the number of parity drives for MinIO server in Standard mode. Objects are stored in Standard mode, if storage class is not defined in Put request

### Összefoglalás

Összegzésül, deklarálod **egyszer** a paraméterek, body, stb típusát funkciós paraméterekként.

Ezt standard modern Python típusokkal csinálod.

Nem kell új szintaxist, vagy specifikus könyvtár mert metódósait, stb. megtanulnod.

Csak standard **Python**.

Például egy `int`-nek:

```Python
item_id: int
```

Egy komplexebb `Item` modellnek:

```Python

// similar attributes and is identified by a pair of strings: the name of the FlowSchema and a "flow distinguisher".
message FlowSchema {
  // `metadata` is the standard object's metadata.
  // More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
  // +optional
  optional k8s.io.apimachinery.pkg.apis.meta.v1.ObjectMeta metadata = 1;

Isso é provavelmente o que você faria quando você quisesse lançar sua aplicação em produção:

```
pip install fastapi
```

Também instale o `uvicorn` para funcionar como servidor:

```
pip install "uvicorn[standard]"
```

E o mesmo para cada dependência opcional que você quiser usar.
