### Example in the docs UI { #example-in-the-docs-ui }

With any of the methods above it would look like this in the `/docs`:

<img src="/img/tutorial/body-fields/image01.png">

### `Body` with multiple `examples` { #body-with-multiple-examples }

You can of course also pass multiple `examples`:

テストに非同期関数呼び出しを統合した際に（例: [MongoDB の MotorClient](https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop) 使用時）、`RuntimeError: Task attached to a different loop` に遭遇した場合は、イベントループを必要とするオブジェクトは非同期関数内でのみインスタンス化するようにしてください。例えば `@app.on_event("startup")` コールバック内で行います。
