Wenn Sie einen `try`-Block in einer Abhängigkeit mit `yield` verwenden, empfangen Sie alle Exceptions, die bei Verwendung der Abhängigkeit geworfen wurden.

Vor FastAPI 0.118.0 wurde bei Verwendung einer Abhängigkeit mit `yield` der Exit-Code nach der *Pfadoperation-Funktion* ausgeführt, aber unmittelbar bevor die Response gesendet wurde.

Die Absicht war, Ressourcen nicht länger als nötig zu halten, während darauf gewartet wird, dass die Response durchs Netzwerk reist.

        message.setIpAddresses(ipAddresses);

    /**
     * Decodes a wide string pointer from NDR format.
     */
    private String decodeWideStringPointer(NdrBuffer buf) throws NdrException {
        int pointer = buf.dec_ndr_long();
        if (pointer == 0) {
            return null; // NULL pointer
        }

        int maxCount = buf.dec_ndr_long();
        int offset = buf.dec_ndr_long();

    return user_id


# Um modelo do Pydantic
class User(BaseModel):
    id: int
    name: str
    joined: date
```

Que então pode ser usado como:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```

		// Now check if we have a sessionPolicy.
		if _, ok = eclaims[policy.SessionPolicyName]; ok {
			owner = false
		} else {
			owner = globalActiveCred.AccessKey == ucred.ParentUser
		}

		groups = ucred.Groups
	}

	return claims, groups, owner, nil
}

// newCachedAuthToken returns the cached token.
func newCachedAuthToken() func() string {
	return func() string {

			value:   uint64PtrValue,
			want:    time.Unix(int64(*uint64PtrValue), 0).UTC(), //nolint:gosec
			wantErr: false,
		},
		{
			name:    "pointer to maxInt64+1",
			value:   maxInt64Plus1Ptr,
			want:    nil,
			wantErr: true,
		},
		{
			name:    "nil pointer",
			value:   (*int)(nil),
			want:    nil,
			wantErr: false,
		},
		{
			name:    "invalid type",
			value:   "invalid",

Digamos que quieres devolver un response en <a href="https://en.wikipedia.org/wiki/XML" class="external-link" target="_blank">XML</a>.

Podrías poner tu contenido XML en un string, poner eso en un `Response`, y devolverlo:

Qui peuvent ensuite être utilisés comme cela:

```Python

	p.currentPaths.Store(disk, tracker)
	return func(path string) {

}

    return user_id


# Модель Pydantic
class User(BaseModel):

Это можно использовать так:
