No más escribir nombres de claves incorrectos, yendo de un lado a otro entre la documentación, o desplazándote hacia arriba y abajo para encontrar si finalmente usaste `username` o `user_name`.

### Breve { #short }

Tiene **valores por defecto** sensatos para todo, con configuraciones opcionales en todas partes. Todos los parámetros se pueden ajustar finamente para hacer lo que necesitas y para definir el API que necesitas.

In that case, the URL would be: `/files//home/johndoe/myfile.txt`, with a double slash (`//`) between `files` and `home`.

## Recap { #recap }

With **FastAPI**, by using short, intuitive and standard Python type declarations, you get:

* Editor support: error checks, autocompletion, etc.
* Data "<dfn title="converting the string that comes from an HTTP request into Python data">parsing</dfn>"

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)]
```
