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。 但是您不能从退出代码中引发另一个异常(在yield之后)。可以查阅 [Dependencies with yield and HTTPException](https://fastapi.tiangolo.com/zh/tutorial/dependencies/dependencies-with-yield/#dependencies-with-yield-and-httpexception) *然后,当在路径操作函数*中使用依赖项时,我们使用`Session`,直接从 SQLAlchemy 导入的类型声明它。 *这将为我们在路径操作函数*中提供更好的编辑器支持,因为编辑器将知道`db`参数的类型`Session`:

* It can do something to that **response** or run any needed code. * Then it returns the **response**. !!! note "Technical Details" If you have dependencies with `yield`, the exit code will run *after* the middleware. If there were any background tasks (documented later), they will run *after* all the middleware. ## Create a middleware

* Sie kann etwas mit dieser **Response** tun oder beliebigen Code ausführen. * Dann gibt sie die **Response** zurück. !!! note "Technische Details" Wenn Sie Abhängigkeiten mit `yield` haben, wird der Exit-Code *nach* der Middleware ausgeführt. Wenn es Hintergrundaufgaben gab (später dokumentiert), werden sie *nach* allen Middlewares ausgeführt. ## Erstellung einer Middleware

* 它接收你的应用程序的每一个**请求**. * 然后它可以对这个**请求**做一些事情或者执行任何需要的代码. * 然后它将**请求**传递给应用程序的其他部分 (通过某种*路径操作*). * 然后它获取应用程序生产的**响应** (通过某种*路径操作*). * 它可以对该**响应**做些什么或者执行任何需要的代码. * 然后它返回这个 **响应**. !!! note "技术细节" 如果你使用了 `yield` 关键字依赖, 依赖中的退出代码将在执行中间件*后*执行. 如果有任何后台任务(稍后记录), 它们将在执行中间件*后*运行. ## 创建中间件 要创建中间件你可以在函数的顶部使用装饰器 `@app.middleware("http")`. 中间件参数接收如下参数: * `request`. * 一个函数 `call_next` 它将接收 `request` 作为参数.

```{ .python .annotate hl_lines="1 5 8-11 14-17 23-25 28" } {!../../../docs_src/dataclasses/tutorial003.py!} ``` 1. We still import `field` from standard `dataclasses`. 2. `pydantic.dataclasses` is a drop-in replacement for `dataclasses`. 3. The `Author` dataclass includes a list of `Item` dataclasses.
