* `version`: The version of your API, e.g. `2.5.0`.
* `openapi_version`: The version of the OpenAPI specification used. By default, the latest: `3.1.0`.
* `summary`: A short summary of the API.
* `description`: The description of your API, this can include markdown and will be shown in the docs.
* `routes`: A list of routes, these are each of the registered *path operations*. They are taken from `app.routes`.

## レスポンスの説明

`response_description`パラメータでレスポンスの説明をすることができます。

```Python hl_lines="21"
{!../../../docs_src/path_operation_configuration/tutorial005.py!}
```

!!! info "情報"
    `respnse_description`は具体的にレスポンスを参照し、`description`は*path operation*全般を参照していることに注意してください。

!!! check "確認"
    OpenAPIは*path operation*ごとにレスポンスの説明を必要としています。

Наприклад, ця модель вище оголошує JSON "`об'єкт`" (або Python `dict`), як:

```JSON
{
    "name": "Foo",
    "description": "An optional description",
    "price": 45.2,
    "tax": 3.5
}
```

...оскільки `description` і `tax` є необов'язковими (зі значенням за замовчуванням `None`), цей JSON "`об'єкт`" також буде дійсним:

```JSON
{
    "name": "Foo",
    "price": 45.2
}

  <artifactId>maven-resources-plugin</artifactId>
  <version>0.1</version>
  <packaging>maven-plugin</packaging>

  <name>Maven Integration Test Plugin</name>
  <description>
    A test plugin to assist testing of Maven core.
  </description>
  <inceptionYear>2009</inceptionYear>

  <distributionManagement>
    <repository>
      <id>maven-core-it</id>
      <url>file:///${basedir}/repo</url>
    </repository>

In diesem Fall erwartet **FastAPI** einen Body wie:

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

statt:

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

## Zusammenfassung

        description = "Run cross-version tests against a limited set of versions"
        group = ciGroup
    }

    register("allVersionsCrossVersionTest") {
        description = "Run cross-version tests against all released versions (latest patch release of each)"
        group = ciGroup
    }

    register("allVersionsIntegMultiVersionTest") {

 * See the License for the specific language governing permissions and
 * limitations under the License.
 */

plugins {
    id("java-library")
}
description = "Provides a custom CodeNarc rule used by the Gradle build"

java {
    toolchain {
        languageVersion = JavaLanguageVersion.of(11)
        vendor = JvmVendorSpec.ADOPTIUM
    }
}

    ```

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

你可以添加多个请求体参数到*路径操作函数*中，即使一个请求只能有一个请求体。

```Python hl_lines="3  5-6"
{
    "name": "Baz",
    "description": None,
    "price": 50.2,
    "tax": 10.5,
    "tags": []
}
```
