# 配置 Swagger UI

你可以配置一些额外的 <a href="https://swagger.io/docs/open-source-tools/swagger-ui/usage/configuration/" class="external-link" target="_blank">Swagger UI 参数</a>.

如果需要配置它们，可以在创建 `FastAPI()` 应用对象时或调用 `get_swagger_ui_html()` 函数时传递 `swagger_ui_parameters` 参数。

`swagger_ui_parameters` 接受一个直接传递给 Swagger UI的字典，包含配置参数键值对。

FastAPI会将这些配置转换为 **JSON**，使其与 JavaScript 兼容，因为这是 Swagger UI 需要的。

## 不使用语法高亮

比如，你可以禁用 Swagger UI 中的语法高亮。

    private long lastWriteTime;

    /**
     * Constructs an Open AndX response.
     *
     * @param config the configuration
     */
    public SmbComOpenAndXResponse(final Configuration config) {
        super(config);
    }

    /**
     * Constructs an Open AndX response with a chained response.
     *
     * @param config the configuration

      eventSequence.forEach loop@{

        }
      }
      Assertions.fail<Any>("event $e without matching start event")
    }
  }

Ein **Kontextmanager** in Python ist etwas, das Sie in einer `with`-Anweisung verwenden können, zum Beispiel kann `open()` als Kontextmanager verwendet werden:

```Python
with open("file.txt") as file:
    file.read()
```

In neueren Versionen von Python gibt es auch einen **asynchronen Kontextmanager**. Sie würden ihn mit `async with` verwenden:

```Python

package jcifs.smb1.dcerpc.msrpc;

import jcifs.smb1.dcerpc.rpc;

/**
 * MS-RPC SAMR open domain operation.
 *
 * This class implements the SAMR OpenDomain operation for obtaining
 * a handle to a specific domain in the Security Account Manager.
 */
public class MsrpcSamrOpenDomain extends samr.SamrOpenDomain {

    /**
     * Creates a new request to open a domain handle.
     *
     * @param handle the SAM policy handle

        when(fileHandle.isValid()).thenReturn(true);
        when(fileHandle.getTree()).thenReturn(tree);

        // Initially not open (isStale returns false when handle is null, not true)
        assertFalse(target.isOpen());
        assertFalse(target.isStale());

        // After ensureOpen, handle valid -> open
        SmbFileHandleImpl fh = target.ensureOpen();
        assertSame(fileHandle, fh);
        assertTrue(target.isOpen());

Менеджер контекста в Python — это то, что можно использовать в операторе `with`. Например, `open()` можно использовать как менеджер контекста:

```Python
with open("file.txt") as file:
    file.read()
```

В последних версиях Python есть также асинхронный менеджер контекста. Его используют с `async with`:

```Python
async with lifespan(app):

import org.codelibs.fess.util.ComponentUtil;
import org.lastaflute.web.response.StreamResponse;
import org.lastaflute.web.util.LaServletContextUtil;

import jakarta.annotation.PostConstruct;

/**
 * Helper class for Open Search Description Document.
 */
public class OsddHelper {

    /**
     * Default constructor.
     */
    public OsddHelper() {
        // Default constructor
    }
