<font color="#3465A4">INFO    </font> Using path <font color="#3465A4">main.py</font>
<font color="#3465A4">INFO    </font> Resolved absolute path <font color="#75507B">/home/user/code/awesomeapp/</font><font color="#AD7FA8">main.py</font>
<font color="#3465A4">INFO    </font> Searching for package file structure from directories with <font color="#3465A4">__init__.py</font> files

En este caso tendrías que asegurarte de que sea único para cada operación.

```Python hl_lines="6"
{!../../docs_src/path_operation_advanced_configuration/tutorial001.py!}
```

### Usando el nombre de la *función de la operación de path* en el operationId

```Python hl_lines="4"
{!../../docs_src/body/tutorial001.py!}
```

## Crie seu modelo de dados

Então você declara seu modelo de dados como uma classe que herda `BaseModel`.

Utilize os tipos Python padrão para todos os atributos:

```Python hl_lines="7-11"
{!../../docs_src/body/tutorial001.py!}
```

All we need to do is handle the request inside a `try`/`except` block:

{* ../../docs_src/custom_request_and_route/tutorial002.py hl[13,15] *}

If an exception occurs, the`Request` instance will still be in scope, so we can read and make use of the request body when handling the error:

{* ../../docs_src/custom_request_and_route/tutorial002.py hl[16:18] *}

## Custom `APIRoute` class in a router

```Python hl_lines="1  4  7-9"
{!../../docs_src/extending_openapi/tutorial001.py!}
```

### Das OpenAPI-Schema generieren

Verwenden Sie dann dieselbe Hilfsfunktion, um das OpenAPI-Schema innerhalb einer `custom_openapi()`-Funktion zu generieren:

```Python hl_lines="2  15-21"
{!../../docs_src/extending_openapi/tutorial001.py!}
```

### Das OpenAPI-Schema ändern

但 FastAPI 还可以使用数据类（<a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a>）：

```Python hl_lines="1  7-12  19-20"
{!../../docs_src/dataclasses/tutorial001.py!}
```

这还是借助于 **Pydantic** 及其<a href="https://pydantic-docs.helpmanual.io/usage/dataclasses/#use-of-stdlib-dataclasses-with-basemodel" class="external-link" target="_blank">内置的 `dataclasses`</a>。

```Python hl_lines="10"
{!../../docs_src/dependencies/tutorial011.py!}
```

# Variables containing version strings extracted from the canonical sources:
# tensorflow/core/public/version.h and tools/pip_package/setup.py.
#
# These variables aren't available by default. Scripts must source this file
# explicitly, *after* checking if update_version.py needs to be run for a
# nightly job. update_version.py affects TF_VER_SUFFIX, TF_VER_PYTHON, and
# TF_VER_FULL.

我们建议使用 **FastAPI** 的安全工具。

## 概览

首先，看看下面的代码是怎么运行的，然后再回过头来了解其背后的原理。

## 创建 `main.py`

把下面的示例代码复制到 `main.py`：
