# Concurrency ve async / await

*path operasyon fonksiyonu* için `async def `sözdizimi,  asenkron kod, eşzamanlılık ve paralellik hakkında bazı ayrıntılar.

Eğer `await` ile çağrılması gerektiğini belirten üçüncü taraf kütüphaneleri kullanıyorsanız, örneğin:

```Python
results = await some_library()
```

# ボディ - 複数のパラメータ

これまで`Path`と`Query`をどう使うかを見てきましたが、リクエストボディの宣言のより高度な使い方を見てみましょう。

## `Path`、`Query`とボディパラメータを混ぜる

まず、もちろん、`Path`と`Query`とリクエストボディのパラメータの宣言は自由に混ぜることができ、 **FastAPI** は何をするべきかを知っています。

また、デフォルトの`None`を設定することで、ボディパラメータをオプションとして宣言することもできます:

{* ../../docs_src/body_multiple_params/tutorial001.py hl[19,20,21] *}

/// note | 備考

この場合、ボディから取得する`item`はオプションであることに注意してください。デフォルト値は`None`です。

///

## 複数のボディパラメータ

        "keywords_path": "${fess.dictionary.path}da/protwords.txt"
      },
      "danish_stemmer": {
        "type":       "stemmer",
        "language":   "danish"
      },
      "dutch_stop": {
        "type":       "stop",
        "stopwords":  "_dutch_"
      },
      "dutch_keywords": {
        "type":       "keyword_marker",
        "keywords_path": "${fess.dictionary.path}nl/protwords.txt"
      },

For that you need to access the request directly.

{* ../../docs_src/using_request_directly/tutorial001.py hl[1,7:8] *}

By declaring a *path operation function* parameter with the type being the `Request` **FastAPI** will know to pass the `Request` in that parameter.

/// tip

Note that in this case, we are declaring a path parameter beside the request parameter.

    have prod supersource, even if they have none. GWT is happy to ignore us
    when we specify a nonexistent path.

    (I hope that this workaround does not cause its own problems in the future.)
