## 一个文件结构示例

假设你的文件结构如下：

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   ├── dependencies.py
│   └── routers
│   │   ├── __init__.py
│   │   ├── items.py
│   │   └── users.py
│   └── internal
│       ├── __init__.py
│       └── admin.py
```

!!! tip
    上面有几个 `__init__.py` 文件：每个目录或子目录中都有一个。

    这就是能将代码从一个文件导入到另一个文件的原因。

    例如，在 `app/main.py` 中，你可以有如下一行：

        TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm()).apply {
          init(null as KeyStore?)
        }.trustManagers.first() as X509TrustManager

      val sslContext =
        Platform.get().newSSLContext().apply {
          // TODO remove most of this code after https://github.com/bcgit/bc-java/issues/686
          init(null, arrayOf(trustManager), SecureRandom())
        }

      client =

=== ":material-language-kotlin: Kotlin"
    ```kotlin
      private val client: OkHttpClient

      init {
        val trustManager = trustManagerForCertificates(trustedCertificatesInputStream())
        val sslContext = SSLContext.getInstance("TLS")
        sslContext.init(null, arrayOf<TrustManager>(trustManager), null)
        val sslSocketFactory = sslContext.socketFactory

  }

  @Throws(IOException::class)
  open fun connectSocket(
    socket: Socket,
    address: InetSocketAddress,
    connectTimeout: Int,
  ) {
    socket.connect(address, connectTimeout)
  }

  open fun log(
    message: String,
    level: Int = INFO,
    t: Throwable? = null,
  ) {
    val logLevel = if (level == WARN) Level.WARNING else Level.INFO
    logger.log(logLevel, message, t)
  }

```

So, again, we should declare the *path operation functions* and the dependency without `async def`, just with a normal `def`, as:

```Python hl_lines="2"
# Something goes here
def read_users(skip: int = 0, limit: int = 100):
    # Something goes here
```

## Testing Peewee with async

This example includes an extra *path operation* that simulates a long processing request with `time.sleep(sleep_time)`.

In beiden Fällen wird sie haben:

* Einen optionalen `q`-Query-Parameter, der ein `str` ist.
* Einen `skip`-Query-Parameter, der ein `int` ist, mit einem Defaultwert `0`.
* Einen `limit`-Query-Parameter, der ein `int` ist, mit einem Defaultwert `100`.

In beiden Fällen werden die Daten konvertiert, validiert, im OpenAPI-Schema dokumentiert, usw.

## Verwendung

В обоих случаях она будет иметь:

* Необязательный параметр запроса `q`, представляющий собой `str`.
* Параметр запроса `skip`, представляющий собой `int`, по умолчанию `0`.
* Параметр запроса `limit`, представляющий собой `int`, по умолчанию равный `100`.

В обоих случаях данные будут конвертированы, валидированы, документированы по схеме OpenAPI и т.д.
