Você apenas envia para `Depends` e o **FastAPI** sabe como fazer o resto.

///

## Compartilhando dependências `Annotated` { #share-annotated-dependencies }

Nos exemplos acima, você pode ver que existe uma pequena **duplicação de código**.

```

这样，你只需编写一次共享代码，**FastAPI** 会在你的*路径操作*中为你调用它。

/// check | 检查

注意，无需创建专门的类并传给 **FastAPI** 去“注册”之类的操作。

只要把它传给 `Depends`，**FastAPI** 就知道该怎么做了。

## 共享 `Annotated` 依赖项 { #share-annotated-dependencies }

在上面的示例中，你会发现这里有一点点**代码重复**。

当你需要使用 `common_parameters()` 这个依赖时，你必须写出完整的带类型注解和 `Depends()` 的参数：

```Python
commons: Annotated[dict, Depends(common_parameters)]
```
