Dieses Beispiel ist jedoch immer noch gültig und zeigt, wie mit den internen Komponenten interagiert wird.

///

Wir können denselben Ansatz auch verwenden, um in einem Exceptionhandler auf den Requestbody zuzugreifen.

Alles, was wir tun müssen, ist, den Request innerhalb eines `try`/`except`-Blocks zu handhaben:

```Python hl_lines="13  15"
{!../../docs_src/custom_request_and_route/tutorial002.py!}
```

BINARIES:=$(STANDARD_BINARIES) $(AGENT_BINARIES) $(LINUX_AGENT_BINARIES)

# List of binaries that have their size tested
RELEASE_SIZE_TEST_BINARIES:=pilot-discovery pilot-agent istioctl envoy ztunnel client server

# agent: enables agent-specific files. Usually this is used to trim dependencies where they would be hard to trim through standard refactoring
# disable_pgv: disables protoc-gen-validation. This is not used buts adds many MB to Envoy protos

    /**
     * Returns the type of this SID indicating the state or type of account.
     * <p>
     * SID types are described in the following table.
     * <tt>

**FastAPI** is helemaal gebaseerd op deze type hints, ze geven veel voordelen.

Maar zelfs als je **FastAPI** nooit gebruikt, heb je er baat bij om er iets over te leren.

Als je een Python expert bent en alles al weet over type hints, sla dan dit hoofdstuk over.

## Motivatie

Laten we beginnen met een eenvoudig voorbeeld:

```Python
{!../../docs_src/python_types/tutorial001.py!}
```

- Watch will now support...

    int[] cellColumnIndices = new int[cellSet().size()];
    int i = 0;
    for (Cell<R, C, V> cell : cellSet()) {
      // requireNonNull is safe because the cell exists in the table.
      cellColumnIndices[i++] = requireNonNull(columnKeyToIndex.get(cell.getColumnKey()));
    }
    return SerializedForm.create(this, cellRowIndices, cellColumnIndices);
  }

    * Old behavior:
      * environment variables explicitly whitelisted via --docker-env-metadata-whitelist were exported as `container_env_*=*`. Default is zero so by default non were exported
      * all docker labels were exported as `container_label_*=*`

	}

	// Log error, as we will not propagate it to caller
	internalLogIf(GlobalContext, err)

	return err == nil
}

// MinIO Helm chart uses DownwardAPIFile to write pod label info to /podinfo/labels
// More info: https://kubernetes.io/docs/tasks/inject-data-application/downward-api-volume-expose-pod-information/#store-pod-fields
// Check if this is Helm package installation and report helm chart version

		Use:   "set <revision-tag>",
		Short: "Create or modify revision tags",
