[*路径装饰器依赖项*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank} 一章的思路均适用于全局依赖项， 在本例中，这些依赖项可以用于应用中的所有*路径操作*。

## 为一组路径操作定义依赖项

## *경로 작동* 모음에 대한 의존성

E `items_per_user` manteria o valor padrão de `50`.

## Configurações em um módulo separado

Você também pode incluir essas configurações em um arquivo de um módulo separado como visto em [Bigger Applications - Multiple Files](../tutorial/bigger-applications.md){.internal-link target=\_blank}.

Por exemplo, você pode adicionar um arquivo `config.py` com:

```Python
{!../../docs_src/settings/app01/config.py!}
```

And your **FastAPI** application might also be composed of several files/modules, etc.

### **FastAPI** app file

Let's say you have a file structure as described in [Bigger Applications](bigger-applications.md){.internal-link target=_blank}:

```
.
├── app
│   ├── __init__.py
│   └── main.py
```

In the file `main.py` you have your **FastAPI** app:


```Python

* API machinery's httpstream/spdy calls now support CIDR notation for NO_PROXY ([#54413](https://github.com/kubernetes/kubernetes/pull/54413), [@kad](https://github.com/kad))
* fix a bug where disk pressure could trigger prematurely when using overlay2 ([#53684](https://github.com/kubernetes/kubernetes/pull/53684), [@dashpole](https://github.com/dashpole))

///

然后，`admin_email` 设置将为 `"******@****.***"`。

`app_name` 将为 `"ChimichangApp"`。

而 `items_per_user` 将保持其默认值为 `50`。

## 在另一个模块中设置

您可以将这些设置放在另一个模块文件中，就像您在[Bigger Applications - Multiple Files](../tutorial/bigger-applications.md){.internal-link target=_blank}中所见的那样。

例如，您可以创建一个名为 `config.py` 的文件，其中包含以下内容：

```Python
{!../../docs_src/settings/app01/config.py!}
```

然后在一个名为 `main.py` 的文件中使用它：

  }

  // A random value that cannot be 0 and that is unsigned-less-than or equal
  // to the given dividend, so that we don't have half of our divisions being
  // trivial because the divisor is bigger than the dividend.
  // Using remainder here does not give us a uniform distribution but it should
  // not have a big impact on the measurement.
  private static long randomDivisor(long dividend) {
