```Python hl_lines="1  3" title="app/routers/users.py"

```

### *Path operations* with `APIRouter`

And then you use it to declare your *path operations*.

Use it the same way you would use the `FastAPI` class:

```Python hl_lines="6  11  16" title="app/routers/users.py"
{!../../../docs_src/bigger_applications/app/routers/users.py!}
```

你可以导入它并通过与 `FastAPI` 类相同的方式创建一个「实例」：

```Python hl_lines="1  3" title="app/routers/users.py"
{!../../../docs_src/bigger_applications/app/routers/users.py!}
```

### 使用 `APIRouter` 的*路径操作*

然后你可以使用它来声明*路径操作*。

使用方式与 `FastAPI` 类相同：

```Python hl_lines="6  11  16" title="app/routers/users.py"
{!../../../docs_src/bigger_applications/app/routers/users.py!}
```

你可以将 `APIRouter` 视为一个「迷你 `FastAPI`」类。

所有相同的选项都得到支持。

## Dependencies for groups of *path operations*

## Зависимости для групп *операций пути*

```

[*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

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

    * So, by using FastAPI you are saving development time, bugs, lines of code, and you would probably get the same performance (or better) you would if you didn't use it (as you would have to implement...

```Python hl_lines="9  14"
{!../../../docs_src/dependencies/tutorial006.py!}
```

    * De ce fait, en utilisant FastAPI on minimise le temps de développement, les bugs, le nombre de lignes de code, et on obtient les mêmes performances (si ce n'est de meilleurs performances) que l'on aurait pu avoir sans ce framework (en ayant à implémenter de nombreuses fonctionnalités importantes par nous-mêmes).

## *경로 작동* 모음에 대한 의존성

나중에 여러 파일을 가지고 있을 수 있는 더 큰 애플리케이션을 구조화하는 법([더 큰 애플리케이션 - 여러 파일들](../../tutorial/bigger-applications.md){.internal-link target=_blank})을 읽을 때, *경로 작동* 모음에 대한 단일 `dependencies` 매개변수를 선언하는 법에 대해서 배우게 될 것입니다.
