    ## Example

    ```python
    from fastapi import FastAPI, HTTPException

    app = FastAPI()

    items = {"foo": "The Foo Wrestlers"}


    @app.get("/items/{item_id}")
    async def read_item(item_id: str):
        if item_id not in items:
            raise HTTPException(status_code=404, detail="Item not found")

If the client requests `http://example.com/items/foo` (an `item_id` `"foo"`), that client will receive an HTTP status code of 200, and a JSON response of:

```JSON
{
  "item": "The Foo Wrestlers"
}
```

But if the client requests `http://example.com/items/bar` (a non-existent `item_id` `"bar"`), that client will receive an HTTP status code of 404 (the "not found" error), and a JSON response of:

```JSON
{

### レスポンス結果 { #the-resulting-response }

クライアントが`http://example.com/items/foo`（`item_id` `"foo"`）をリクエストすると、HTTPステータスコードが200で、以下のJSONレスポンスが返されます:

```JSON
{
  "item": "The Foo Wrestlers"
}
```

しかし、クライアントが`http://example.com/items/bar`（存在しない`item_id` `"bar"`）をリクエストした場合、HTTPステータスコード404（"not found"エラー）と以下のJSONレスポンスが返されます:

```JSON
{
  "detail": "Item not found"
}
```

/// tip | 豆知識

    client = TestClient(mod.app)
    return client


def test_update(client: TestClient):
    response = client.put("/items/foo", json={"name": "Wrestlers"})
    assert response.status_code == 200, response.text
    assert response.json() == {"name": "Wrestlers", "size": None}


def test_create(client: TestClient):
    response = client.put("/items/red", json={"name": "Chillies"})

### Возвращаемый ответ { #the-resulting-response }

Если клиент запросит `http://example.com/items/foo` (`item_id` `"foo"`), то он получит статус-код 200 и ответ в формате JSON:

```JSON
{
  "item": "The Foo Wrestlers"
}
```

Но если клиент запросит `http://example.com/items/bar` (несуществующий `item_id` `"bar"`), то он получит статус-код 404 (ошибка "не найдено") и JSON-ответ в виде:

```JSON
{
  "detail": "Item not found"

Wenn der Client `http://example.com/items/foo` anfordert (ein `item_id` `"foo"`), erhält dieser Client einen HTTP-Statuscode 200 und diese JSON-Response:

```JSON
{
  "item": "The Foo Wrestlers"
}
```

Aber wenn der Client `http://example.com/items/bar` anfordert (ein nicht-existierendes `item_id` `"bar"`), erhält er einen HTTP-Statuscode 404 (der „Not Found“-Error) und eine JSON-Response wie:

```JSON
{

### Réponse résultante { #the-resulting-response }

Si le client demande `http://example.com/items/foo` (un `item_id` « foo »), il recevra un code d'état HTTP 200 et une réponse JSON :

```JSON
{
  "item": "The Foo Wrestlers"
}
```

Mais si le client demande `http://example.com/items/bar` (un `item_id` inexistant « bar »), il recevra un code d'état HTTP 404 (l'erreur « not found ») et une réponse JSON :

```JSON
{
