# 测试 WebSockets { #testing-websockets }

你可以使用同一个 `TestClient` 来测试 WebSockets。

为此，在 `with` 语句中使用 `TestClient` 连接到 WebSocket：

{* ../../docs_src/app_testing/tutorial002_py310.py hl[27:31] *}

/// note | 注意

更多细节请查看 Starlette 的文档：[测试 WebSockets](https://www.starlette.dev/testclient/#testing-websocket-sessions)。

# 測試 WebSocket { #testing-websockets }

你可以使用相同的 `TestClient` 來測試 WebSocket。

為此，你可以在 `with` 陳述式中使用 `TestClient`，連線到該 WebSocket：

{* ../../docs_src/app_testing/tutorial002_py310.py hl[27:31] *}

/// note | 注意

...그럼 Swagger UI에서 더 이상 구문 강조 기능이 표시되지 않습니다:

<img src="/img/tutorial/extending-openapi/image03.png">

## 테마 변경 { #change-the-theme }

동일한 방식으로 `"syntaxHighlight.theme"` 키를 사용하여 구문 강조 테마를 설정할 수 있습니다 (중간에 점이 포함된 것을 참고하십시오).

{* ../../docs_src/configure_swagger_ui/tutorial002_py310.py hl[3] *}

이 설정은 구문 강조 색상 테마를 변경합니다:

**FastAPI** supports that the same way as with plain strings:

{* ../../docs_src/path_operation_configuration/tutorial002b_py310.py hl[1,8:10,13,18] *}

## Summary and description { #summary-and-description }

You can add a `summary` and `description`:

{* ../../docs_src/path_operation_configuration/tutorial003_py310.py hl[17:18] *}

## Description from docstring { #description-from-docstring }

You can declare a parameter of type `Response` in your *path operation function*.

And then you can set cookies in that *temporal* response object.

{* ../../docs_src/response_cookies/tutorial002_py310.py hl[1, 8:9] *}

And then you can return any object you need, as you normally would (a `dict`, a database model, etc).

{* ../../docs_src/configure_swagger_ui/tutorial002_py310.py hl[3] *}

That configuration would change the syntax highlighting color theme:

<img src="/img/tutorial/extending-openapi/image04.png">

## Change Default Swagger UI Parameters { #change-default-swagger-ui-parameters }

{* ../../docs_src/response_directly/tutorial002_py310.py hl[1,18] *}

### `HTMLResponse` { #htmlresponse }

Takes some text or bytes and returns an HTML response, as you read above.

### `PlainTextResponse` { #plaintextresponse }

Takes some text or bytes and returns a plain text response.

{* ../../docs_src/custom_response/tutorial005_py310.py hl[2,7,9] *}

### `JSONResponse` { #jsonresponse }

但你可以將 `syntaxHighlight` 設為 `False` 來停用它：

{* ../../docs_src/configure_swagger_ui/tutorial001_py310.py hl[3] *}

...然後 Swagger UI 就不會再顯示語法醒目提示：

<img src="/img/tutorial/extending-openapi/image03.png">

## 更換主題 { #change-the-theme }

同樣地，你可以用鍵 `"syntaxHighlight.theme"` 設定語法醒目提示主題（注意中間有一個點）：

{* ../../docs_src/configure_swagger_ui/tutorial002_py310.py hl[3] *}

這個設定會變更語法醒目提示的配色主題：

## Simple code includes { #simple-code-includes }

{* ../../docs_src/python_types/tutorial001_py310.py *}

{* ../../docs_src/python_types/tutorial002_py310.py *}


## Code includes with highlighting { #code-includes-with-highlighting }

{* ../../docs_src/python_types/tutorial002_py310.py hl[1] *}

{* ../../docs_src/python_types/tutorial006_py310.py hl[10] *}
