### 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"
}
```

import org.elasticsearch.gradle.internal.test.rest.transform.ReplaceByKey;
import org.gradle.api.tasks.Internal;

/**
 * A transformation to replace the key in a match. For example, change from "match":{"index._type": "foo"} to "match":{"index._doc": "foo"}

이 경우 **FastAPI**는 다음과 같은 본문을 예상합니다:

```JSON hl_lines="2"
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,
        "tax": 3.2
    }
}
```

다음 대신에:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

## 정리 { #recap }

在这种情况下，**FastAPI** 将期望像这样的请求体：

```JSON hl_lines="2"
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,
        "tax": 3.2
    }
}
```

而不是：

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

## 总结 { #recap }

    assertThat(Strings.lenientFormat("%s")).isEqualTo("%s");
    assertThat(Strings.lenientFormat("%s", 5)).isEqualTo("5");
    assertThat(Strings.lenientFormat("foo", 5)).isEqualTo("foo [5]");
    assertThat(Strings.lenientFormat("foo", 5, 6, 7)).isEqualTo("foo [5, 6, 7]");
    assertThat(Strings.lenientFormat("%s %s %s", "%s", 1, 2)).isEqualTo("%s 1 2");
    assertThat(Strings.lenientFormat("", 5, 6)).isEqualTo(" [5, 6]");
