Wir deklarieren auch einen speziellen Parameter vom Typ `SecurityScopes`, der aus `fastapi.security` importiert wird.

Diese `SecurityScopes`-Klasse ähnelt `Request` (`Request` wurde verwendet, um das Request-Objekt direkt zu erhalten).

// LookupHost is a function to make custom lookupHost for optional cached DNS requests

// DialContextWithLookupHost is a helper function which returns `net.DialContext` function.

我们将`SessionLocal()`请求的创建和处理放在一个`try`块中。

然后我们在finally块中关闭它。

通过这种方式，我们确保数据库会话在请求后始终关闭，即使在处理请求时出现异常也会关闭。

///

### 关于`request.state`

`request.state`是每个`Request`对象的属性。它用于存储附加到请求本身的任意对象，例如本例中的数据库会话。您可以在[Starlette 的关于`Request`state](https://www.starlette.io/requests/#other-state)的文档中了解更多信息。

对于这种情况下，它帮助我们确保在整个请求中使用单个数据库会话，然后关闭（在中间件中）。

### 使用`yield`依赖项与使用中间件的区别

在此处添加**中间件**与`yield`的依赖项的作用效果类似，但也有一些区别：

                jobLogService.delete(entity);
                saveInfo(messages -> messages.addSuccessCrudDeleteCrudTable(GLOBAL));
            } catch (final Exception e) {
                logger.warn("Failed to process a request.", e);
                throwValidationErrorApi(messages -> messages.addErrorsCrudFailedToDeleteCrudTable(GLOBAL, buildThrowableMessage(e)));
            }
        }).orElse(() -> {

    }

    //                                                                    ================
