注意錯誤也清楚指出驗證未通過的確切位置。

這在開發與除錯與你的 API 互動的程式碼時非常有幫助。

## 文件 { #documentation }

當你在瀏覽器開啟 [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs)，你會看到自動產生、可互動的 API 文件，例如：

<img src="/img/tutorial/path-params/image01.png">

/// check

同樣地，只要使用那個 Python 型別宣告，**FastAPI** 就會提供自動、互動式的文件（整合 Swagger UI）。

注意路徑參數被宣告為整數。

## 基於標準的優勢與替代文件 { #standards-based-benefits-alternative-documentation }

## Dependencies for a group of *path operations* { #dependencies-for-a-group-of-path-operations }

Later, when reading about how to structure bigger applications ([Bigger Applications - Multiple Files](../../tutorial/bigger-applications.md)), possibly with multiple files, you will learn how to declare a single `dependencies` parameter for a group of *path operations*.

## Global Dependencies { #global-dependencies }

## Check the Docs { #check-the-docs }

You can verify it in the docs UI at `/docs`:

<div class="screenshot">
<img src="/img/tutorial/request-form-models/image01.png">
</div>

## Forbid Extra Form Fields { #forbid-extra-form-fields }

<div class="screenshot">
<img src="/img/tutorial/sql-databases/image02.png">
</div>

## 總結 { #recap }

你可以使用 [SQLModel](https://sqlmodel.tiangolo.com/) 與 SQL 資料庫互動，並用「資料模型」與「資料表模型」讓程式碼更簡潔。

**FastAPI** 會從請求收到的 **Cookie** 中擷取 **每個欄位** 的資料，並交給你定義的 Pydantic 模型。

## 查看文件 { #check-the-docs }

你可以在 `/docs` 的文件介面中看到已定義的 Cookie：

<div class="screenshot">
<img src="/img/tutorial/cookie-param-models/image01.png">
</div>

/// info

請注意，由於**瀏覽器會以特殊且在背景進行的方式處理 Cookie**，因此**不會**輕易允許 **JavaScript** 存取它們。

當你前往位於 `/docs` 的 **API 文件介面**時，可以看到路徑操作的 Cookie 說明。

* There's also a subdirectory `app/internal/` with another file `__init__.py`, so it's another "Python subpackage": `app.internal`.
* And the file `app/internal/admin.py` is another submodule: `app.internal.admin`.

The same file structure with comments:

```bash
.
├── app                  # "app" is a Python package
│   ├── __init__.py      # this file makes "app" a "Python package"

[http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs)에서 확인할 수 있습니다:

<img src="/img/tutorial/behind-a-proxy/image01.png">

하지만 프록시(포트 `9999`)를 사용해 "공식" URL인 `/api/v1/docs`에서 docs UI에 접근하면, 올바르게 동작합니다! 🎉

[http://127.0.0.1:9999/api/v1/docs](http://127.0.0.1:9999/api/v1/docs)에서 확인할 수 있습니다:

원하던 그대로입니다. ✔️

## 总结 { #recap }

你可以使用 [**SQLModel**](https://sqlmodel.tiangolo.com/) 与 SQL 数据库进行交互，并通过*数据模型*和*表模型*简化代码。

## Settings in another module { #settings-in-another-module }

You could put those settings in another module file as you saw in [Bigger Applications - Multiple Files](../tutorial/bigger-applications.md).

For example, you could have a file `config.py` with:

{* ../../docs_src/settings/app01_py310/config.py *}

And then use it in a file `main.py`:

    "response model from the type annotation with the path operation decorator "
    "parameter response_model=None. Read more: "
    "https://fastapi.tiangolo.com/tutorial/response-model/"
)


def create_model_field(
    name: str,
    type_: Any,
    default: Any | None = Undefined,
    field_info: FieldInfo | None = None,
    alias: str | None = None,
