### Запуск { #run-it }

Запустите сервер командой:

<div class="termy">

```console
$ fastapi dev

 ╭────────── FastAPI CLI - Development mode ───────────╮

        /*
         * a * b == aHi * bHi * 2^64 + (aHi * bLo + aLo * bHi) * 2^32 + aLo * bLo.
         *       == (aHi * bHi * 2^32 + aHi * bLo + aLo * bHi) * 2^32 + aLo * bLo
         *
         * We carry out this computation in modular arithmetic. Since times2ToThe32Mod accepts any
         * unsigned long, we don't have to do a mod on every operation, only when intermediate
         * results can exceed 2^63.

# 동시성과 async / await { #concurrency-and-async-await }

*경로 처리 함수*에서의 `async def` 문법에 대한 세부사항과 비동기 코드, 동시성 및 병렬성에 대한 배경

## 바쁘신가요? { #in-a-hurry }

<abbr title="too long; didn't read - 너무 길어서 읽지 않음"><strong>TL;DR:</strong></abbr>

다음과 같이 `await`를 사용해 호출하라고 안내하는 제3자 라이브러리를 사용하는 경우:

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

다음처럼 *경로 처리 함수*를 `async def`를 사용해 선언하십시오:

```Python hl_lines="2"
@app.get('/')

この場合、この関数は`async`関数です。

---

`async def`の代わりに通常の関数として定義することもできます:

{* ../../docs_src/first_steps/tutorial003_py310.py hl[7] *}

/// note | 備考

違いが分からない場合は、[Async: *「急いでいますか？」*](../async.md#in-a-hurry)を確認してください。

///

### Step 5: コンテンツの返信 { #step-5-return-the-content }

{* ../../docs_src/first_steps/tutorial001_py310.py hl[8] *}

`dict`、`list`、`str`、`int`などの単一の値を返すことができます。

# 並行処理と async / await { #concurrency-and-async-await }

*path operation 関数*のための `async def` 構文に関する詳細と、非同期コード、並行処理、並列処理の背景についてです。

## 急いでいますか？ { #in-a-hurry }

<abbr title="too long; didn't read - 長すぎて読まなかった"><strong>TL;DR:</strong></abbr>

次のように `await` で呼び出すよう指示されているサードパーティライブラリを使っているなら:

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

*path operation 関数*は次のように `async def` で宣言します:

```Python hl_lines="2"
@app.get('/')

```

### Lancer { #run-it }

Lancez le serveur avec :

<div class="termy">

```console
$ fastapi dev

 ╭────────── FastAPI CLI - Development mode ───────────╮

async def read_item(item_id: int, q: str | None = None):
    return {"item_id": item_id, "q": q}
```

**Not**:

## Version 4.7.0

_2020-05-17_

 *  New: `HandshakeCertificates.Builder.addInsecureHost()` makes it easy to turn off security in
    private development environments that only carry test data. Prefer this over creating an
    all-trusting `TrustManager` because only hosts on the allowlist are insecure. From
    [our DevServer sample][dev_server]:

    ```kotlin

If you need to upgrade a version or add a new package you would **do this again**.

### Install Packages Directly { #install-packages-directly }

If you're in a hurry and don't want to use a file to declare your project's package requirements, you can install them directly.
