您可以发送（和接收）多条消息：

<img src="/img/tutorial/websockets/image04.png">

所有这些消息都将使用同一个 WebSocket 连

接。

## 使用 `Depends` 和其他依赖项

在 WebSocket 端点中，您可以从 `fastapi` 导入并使用以下内容：

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

它们的工作方式与其他 FastAPI 端点/ *路径操作* 相同：

//// tab | Python 3.10+

```Python hl_lines="68-69  82"

 */
@Deprecated(since = "4.0.0")
public interface ModelBuildingEvent {

    /**
     * Gets the model being built. The precise state of this model depends on the event being fired.
     *
     * @return The model being built, never {@code null}.
     */
    Model getModel();

    /**
     * Gets the model building request being processed.
     *

	formatMetaVersionV1 = "1"
)

// format.json currently has the format:
// {
//   "version": "1",
//   "format": "XXXXX",
//   "XXXXX": {
//
//   }
// }
// Here "XXXXX" depends on the backend, currently we have "fs" and "xl" implementations.
// formatMetaV1 should be inherited by backend format structs. Please look at format-fs.go
// and format-xl.go for details.

```

## 現在のユーザーの注入

ですので、 `get_current_user` に対して同様に *path operation* の中で `Depends` を利用できます。

```Python hl_lines="31"
{!../../docs_src/security/tutorial002.py!}
```

Pydanticモデルの `User` として、 `current_user` の型を宣言することに注意してください。

その関数の中ですべての入力補完や型チェックを行う際に役に立ちます。

/// tip | "豆知識"

リクエストボディはPydanticモデルでも宣言できることを覚えているかもしれません。

ここでは `Depends` を使っているおかげで、 **FastAPI** が混乱することはありません。

///

/// check | "確認"

 */

package gradlebuild.buildutils.tasks

import org.gradle.api.tasks.TaskAction
import org.gradle.work.DisableCachingByDefault
import java.util.TreeSet


@DisableCachingByDefault(because = "Depends on GitHub API")
abstract class CheckContributorsInReleaseNotes : AbstractCheckOrUpdateContributorsInReleaseNotes() {
    @TaskAction
    fun check() {

You can send (and receive) many messages:

<img src="/img/tutorial/websockets/image04.png">

And all of them will use the same WebSocket connection.

## Using `Depends` and others

In WebSocket endpoints you can import from `fastapi` and use:

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

They work the same way as for other FastAPI endpoints/*path operations*:

 * probably roll its own.
 * <p>
 * This implementation is backed by Maven Resolver API, supported protocols and transport selection depends on it. If
 * resolver preference regarding transport is altered, it will affect this service as well.
 *
 * @since 4.0.0

@Experimental
@Consumer
public interface TransportProvider extends Service {
    /**

<img src="/img/tutorial/websockets/image04.png">

Und alle verwenden dieselbe WebSocket-Verbindung.

## Verwendung von `Depends` und anderen

In WebSocket-Endpunkten können Sie Folgendes aus `fastapi` importieren und verwenden:

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`
