# Response – Statuscode ändern

Sie haben wahrscheinlich schon vorher gelesen, dass Sie einen Standard-[Response-Statuscode](../tutorial/response-status-code.md){.internal-link target=_blank} festlegen können.

In manchen Fällen müssen Sie jedoch einen anderen als den Standard-Statuscode zurückgeben.

## Anwendungsfall

Stellen Sie sich zum Beispiel vor, Sie möchten standardmäßig den HTTP-Statuscode „OK“ `200` zurückgeben.

// particular topology segment.  This can be used when considering where to
// instantiate new PersistentVolumes.
//
// For example this can express things like:
// - StorageClass "standard" has "1234 GiB" available in "topology.kubernetes.io/zone=us-east1"
// - StorageClass "localssd" has "10 GiB" available in "kubernetes.io/hostname=knode-abc123"
//

                                    "title": "Standard Query Param",
                                }
                            )
                            | IsDict(
                                # TODO: remove when deprecating Pydantic v1
                                {
                                    "title": "Standard Query Param",
                                    "type": "integer",

copies of a package at different versions if the package is
imported normally and vendored by the standard library.

Vendored packages are internally renamed with a "vendor/" prefix
to preserve the invariant that all packages have distinct paths.
This is necessary to avoid compiler and linker conflicts. Adding
a "vendor/" prefix also maintains the invariant that standard
library packages begin with a dotless path element.

	configRRSParityMD = NewGaugeMD(configRRSParity,

Por exemplo, para instalar o Uvicorn:

<div class="termy">

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

---> 100%
```

</div>

Um processo semelhante se aplicaria a qualquer outro programa de servidor ASGI.

/// tip | "Dica"

Adicionando o `standard`, o Uvicorn instalará e usará algumas dependências extras recomendadas.

  // but is not limited to get, list, watch, create, update, patch,

  // custom verbs outside the standard Kubernetes verb set. Clients
  // should expect the behavior of standard verbs to align with
  // Kubernetes interaction conventions.
  // +listType=set
  repeated string verbs = 4;

/// note

When you install with `pip install "fastapi[standard]"` it comes with some default optional standard dependencies.

If you don't want to have those optional dependencies, you can instead install `pip install fastapi`.
