## Встановлення власних обробників помилок

Ви можете додати власні обробники помилок за допомогою <a href="https://www.starlette.dev/exceptions/" class="external-link" target="_blank">тих самих утиліт обробки помилок зі Starlette</a>.

Isso será definido no OpenAPI com `anyOf`.

Para fazer isso, use a anotação de tipo padrão do Python <a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>:

/// note | Nota

Aynı anda paralellik ve asenkronluğa sahip olabildiğiniz için, test edilen NodeJS çerçevelerinin çoğundan daha yüksek performans elde edersiniz ve C'ye daha yakın derlenmiş bir dil olan Go ile eşit bir performans elde edersiniz <a href="https://www.techempower.com/benchmarks/#section=data-r17&hw=ph&test=query&l=zijmkf-1" class="external-link" target="_blank">(bütün teşekkürler Starlette'e )</a>.

### Eşzamanlılık paralellikten daha mı iyi?

# FastAPI全栈模板

模板通常带有特定的设置，而且被设计为灵活和可定制的。这允许您根据项目的需求修改和调整它们，使它们成为一个很好的起点。🏁

您可以使用此模板开始，因为它包含了许多已经为您完成的初始设置、安全性、数据库和一些API端点。

代码仓： <a href="https://github.com/fastapi/full-stack-fastapi-template" class="external-link" target="_blank">Full Stack FastAPI Template</a>

## FastAPI全栈模板 - 技术栈和特性

- ⚡ [**FastAPI**](https://fastapi.tiangolo.com) 用于Python后端API.
    - 🧰 [SQLModel](https://sqlmodel.tiangolo.com) 用于Python和SQL数据库的集成（ORM）。

# 表单模型

您可以使用 **Pydantic 模型**在 FastAPI 中声明**表单字段**。

/// info

要使用表单，需预先安装 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a> 。

确保您创建、激活一个[虚拟环境](../virtual-environments.md){.internal-link target=_blank}后再安装。

```console
$ pip install python-multipart
```

///

/// note

自 FastAPI 版本 `0.113.0` 起支持此功能。🤓
