5. Request body olarak dataclass'larla birlikte diğer standart type annotation'ları da kullanabilirsiniz.

    Bu örnekte, `Item` dataclass'larından oluşan bir listedir.

6. Burada `items` içeren bir dictionary döndürüyoruz; `items` bir dataclass listesi.

    FastAPI, veriyi JSON'a <dfn title="veriyi aktarılabilir bir formata dönüştürme">serileştirme</dfn>yi yine başarır.

例如：

{* ../../docs_src/metadata/tutorial001_1_py310.py hl[31] *}

## 標籤的中繼資料 { #metadata-for-tags }

你也可以透過 `openapi_tags` 參數，為用來分組你的路徑操作（path operation）的各個標籤加入額外中繼資料。

它接收一個 list，其中每個標籤對應一個 dictionary。

每個 dictionary 可包含：

* `name`（**必填**）：一個 `str`，其值需與你在路徑操作與 `APIRouter`s 的 `tags` 參數中使用的標籤名稱相同。
* `description`：一個 `str`，為該標籤的簡短描述。可使用 Markdown，並會顯示在文件介面中。
* `externalDocs`：一個 `dict`，描述外部文件，包含：

Create custom dictionary files in: `${fess.dictionary.path}/[lang]/`

Available dictionary types:
- `stopwords.txt` - Words to exclude from indexing
- `stemmer_override.txt` - Custom stemming rules
- `protwords.txt` - Protected words (no stemming)
- `mapping.txt` - Character/token mappings

**Example directory structure:**
```
dictionary/
└── sv/
    ├── stopwords.txt
