Elle accepte les paramètres suivants :

- `content` - Une `str` ou des `bytes`.
- `status_code` - Un code d'état HTTP de type `int`.
- `headers` - Un `dict` de chaînes.
- `media_type` - Une `str` donnant le media type. Par exemple « text/html ».

Fixer tool expects comments that follow specific pattern:

- For hash-style comments: comment starts with `# ` (hash following by whitespace) in the beginning of the string or after a whitespace.
- For slash-style comments: comment starts with `// ` (two slashes following by whitespace) in the beginning of the string or after a whitespace.

If comment doesn't follow this pattern, fixer tool will not preserve it.

#Function declaration

data: {"name": "Plumbus", "price": 32.99}

SSE se usa comúnmente para streaming de chat de IA, notificaciones en vivo, logs y observabilidad, y otros casos donde el servidor envía actualizaciones al cliente.

/// tip | Consejo

Si quieres hacer streaming de datos binarios, por ejemplo video o audio, Revisa la guía avanzada: [Stream Data](../advanced/stream-data.md).

You are encouraged to use all the tools you want to do your work and contribute as efficiently as possible, this includes AI (LLM) tools, etc. Nevertheless, contributions should have meaningful human intervention, judgement, context, etc.

	Name string

	// Comment is any arbitrary user-defined string shorter than 64KiB.
	Comment string

	// NonUTF8 indicates that Name and Comment are not encoded in UTF-8.
	//
	// By specification, the only other encoding permitted should be CP-437,
	// but historically many ZIP readers interpret Name and Comment as whatever
	// the system's local character encoding happens to be.

Örneğin, bir `async` *path operation function* içinde içeriği şöyle alabilirsiniz:

```Python
contents = await myfile.read()
```

Normal bir `def` *path operation function* içindeyseniz `UploadFile.file`’a doğrudan erişebilirsiniz, örneğin:

```Python
contents = myfile.file.read()
```

/// tip | Consejo

`aGVsbG8=` es la codificación base64 de `hello`.

///

Y luego Pydantic decodificará el string base64 y te dará los bytes originales en el campo `data` del modelo.

Recibirás una response como:

```json
{
  "description": "Some data",
  "content": "hello"
}
```
