如果你想完全禁用 OpenAPI 模式，可以将其设置为 `openapi_url=None`，这样也会禁用使用它的文档用户界面。

## 文档 URLs { #docs-urls }

你可以配置两个文档用户界面，包括：

- **Swagger UI**：服务于 `/docs`。
    - 可以使用参数 `docs_url` 设置它的 URL。
    - 可以通过设置 `docs_url=None` 禁用它。
- **ReDoc**：服务于 `/redoc`。
    - 可以使用参数 `redoc_url` 设置它的 URL。
    - 可以通过设置 `redoc_url=None` 禁用它。

例如，设置 Swagger UI 服务于 `/documentation` 并禁用 ReDoc：

  @GwtIncompatible // Non-UTF-8 Charset
  public void testUtf16be() {
    assertThat(Charsets.UTF_16BE).isEqualTo(Charset.forName("UTF-16BE"));

  @J2ktIncompatible
  @GwtIncompatible // Non-UTF-8 Charset
  public void testUtf16le() {

  }
