Path parametresi `item_id`'nin değeri, fonksiyonunuza `item_id` argümanı olarak aktarılacaktır.

Yani, bu örneği çalıştırıp [http://127.0.0.1:8000/items/foo](http://127.0.0.1:8000/items/foo) adresine giderseniz, şöyle bir response görürsünüz:

```JSON
{"item_id":"foo"}
```

## 嵌入單一 Body 參數 { #embed-a-single-body-parameter }

假設你只有一個來自 Pydantic 模型 `Item` 的單一 `item` Body 參數。

預設情況下，**FastAPI** 會直接期望該模型的內容作為請求主體。

但如果你想讓它像宣告多個 Body 參數時那樣，期望一個帶有 `item` 鍵、其內含模型內容的 JSON，你可以使用 `Body` 的特殊參數 `embed`：

```Python
item: Item = Body(embed=True)
```

如下：

{* ../../docs_src/body_multiple_params/tutorial005_an_py310.py hl[17] *}

from fastapi import Depends, FastAPI

from .dependencies import get_query_token, get_token_header
from .internal import admin
from .routers import items, users

app = FastAPI(dependencies=[Depends(get_query_token)])


app.include_router(users.router)
app.include_router(items.router)
app.include_router(
    admin.router,
    prefix="/admin",
    tags=["admin"],
    dependencies=[Depends(get_token_header)],

    .setSize(10)                        // max suggestions
    .execute()
    .getResponse();

// Process suggestions
response.getItems().forEach(item -> {
    System.out.println("Suggestion: " + item.getText()[0]);
    System.out.println("Score: " + item.getScore());
});
```

#### 4. Asynchronous Suggestions

```java
suggester.suggest()
    .setQuery("sea")
    .execute()

    await websocket.accept()
