### Creando el `Settings` solo una vez con `lru_cache` { #creating-the-settings-only-once-with-lru-cache }

Leer un archivo desde el disco es normalmente una operación costosa (lenta), por lo que probablemente quieras hacerlo solo una vez y luego reutilizar el mismo objeto de configuraciones, en lugar de leerlo para cada request.

Pero cada vez que hacemos:

```Python
Settings()

import jcifs.smb1.dcerpc.ndr.NdrBuffer;
import jcifs.smb1.dcerpc.ndr.NdrException;
import jcifs.smb1.dcerpc.ndr.NdrLong;
import jcifs.smb1.dcerpc.ndr.NdrObject;

/**
 * DCE/RPC interface for Distributed File System (DFS) operations.
 * Provides structures and methods for DFS management and enumeration.
 */
public class netdfs {

    /**
     * Default constructor for netdfs
     */
    public netdfs() {
        // Default constructor

响应(response)对象也拥有自动补全:

## 带有标签的 FastAPI 应用

在许多情况下，你的FastAPI应用程序会更复杂，你可能会使用标签来分隔不同组的*路径操作(path operations)*。

例如，您可以有一个用 `items` 的部分和另一个用于 `users` 的部分，它们可以用标签来分隔：

{* ../../docs_src/generate_clients/tutorial002_py39.py hl[21,26,34] *}

### 生成带有标签的 TypeScript 客户端

如果您使用标签为FastAPI应用生成客户端，它通常也会根据标签分割客户端代码。

Essas variáveis de ambiente só conseguem lidar com strings de texto, pois são externas ao Python e precisam ser compatíveis com outros programas e com o resto do sistema (e até com diferentes sistemas operacionais, como Linux, Windows, macOS).

Isso significa que qualquer valor lido em Python a partir de uma variável de ambiente será uma `str`, e qualquer conversão para um tipo diferente ou validação precisa ser feita em código.

 * Utilities for treating interruptible operations as uninterruptible. In all cases, if a thread is
 * interrupted during such a call, the call continues to block until the result is available or the
 * timeout elapses, and only then re-interrupts the thread.
 *

Nesses casos, você pode usar o parâmetro `response_model` do *decorador de operação de rota* em vez do tipo de retorno.

Você pode usar o parâmetro `response_model` em qualquer uma das *operações de rota*:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
