8. Bu *path operation function*, `async def` yerine normal `def` kullanıyor.

    Her zaman olduğu gibi, FastAPI'de ihtiyaca göre `def` ve `async def`’i birlikte kullanabilirsiniz.

    Hangisini ne zaman kullanmanız gerektiğine dair hızlı bir hatırlatma isterseniz, [`async` ve `await`](../async.md#in-a-hurry) dokümanındaki _"In a hurry?"_ bölümüne bakın.

/**
 * Service class for managing web authentication configurations.
 * Provides CRUD operations for web authentication settings including
 * listing, retrieving, storing, and deleting authentication configurations.
 */
public class WebAuthenticationService {

    /**
     * Default constructor.
     */

* `close()`: Cierra el archivo.

Como todos estos métodos son métodos `async`, necesitas "await" para ellos.

Por ejemplo, dentro de una *path operation function* `async` puedes obtener los contenidos con:

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

Si estás dentro de una *path operation function* normal `def`, puedes acceder al `UploadFile.file` directamente, por ejemplo:

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

为简单起见，此处我们只是把接收到的作用域直接添加到了令牌中。

但在你的应用里，为了安全起见，你应该只添加该用户实际能够拥有的作用域，或你预先定义的作用域。

///

{* ../../docs_src/security/tutorial005_an_py310.py hl[157] *}

## 在*路径操作*与依赖项中声明作用域 { #declare-scopes-in-path-operations-and-dependencies }

现在我们声明，路径操作 `/users/me/items/` 需要作用域 `items`。

为此，从 `fastapi` 导入并使用 `Security`。

你可以用 `Security` 来声明依赖（就像 `Depends` 一样），但 `Security` 还接收一个 `scopes` 参数，其值是作用域（字符串）列表。

為了簡化，這裡我們只是直接把接收到的 scopes 加進 token。

但在你的應用中，為了安全性，你應確保只加入該使用者實際可擁有或你預先定義的 scopes。

///

{* ../../docs_src/security/tutorial005_an_py310.py hl[157] *}

## 在路徑操作與相依性中宣告 scopes { #declare-scopes-in-path-operations-and-dependencies }

現在我們宣告 `/users/me/items/` 這個路徑操作需要 `items` 這個 scope。

為此，我們從 `fastapi` 匯入並使用 `Security`。

你可以使用 `Security` 來宣告相依性（就像 `Depends`），但 `Security` 也能接收參數 `scopes`，其為 scopes（字串）的列表。

        initCause(readFailure)
      }
    }
  }

  abstract val path: Any

  /**
   * Reads the public suffix list treating the operation as uninterruptible. We always want to read
   * the list otherwise we'll be left in a bad state. If the thread was interrupted prior to this
   * operation, it will be re-interrupted after the list is read.
   */
  private fun readTheListUninterruptibly() {
    var interrupted = false
    try {

En este caso, este `__call__` es lo que **FastAPI** usará para comprobar parámetros adicionales y sub-dependencias, y es lo que llamará para pasar un valor al parámetro en tu *path operation function* más adelante.

## Parametrizar la instance { #parameterize-the-instance }

Y ahora, podemos usar `__init__` para declarar los parámetros de la instance que podemos usar para "parametrizar" la dependencia:
