让我们继续之前的文件结构：

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

假设现在包含**FastAPI** app的文件 `main.py`  有些其他**路径操作**。

有个 `GET` 操作会返回错误。

有个 `POST` 操作会返回一些错误。

所有*路径操作* 都需要一个`X-Token` 头。

You could also use `from starlette.requests import Request` and `from starlette.responses import JSONResponse`.

**FastAPI** provides the same `starlette.responses` as `fastapi.responses` just as a convenience for you, the developer. But most of the available responses come directly from Starlette. The same with `Request`.

**FastAPI** has some default exception handlers.

Note that when adding a lazy property to an existing class, you need to check if instances of the class are instantiated via ObjectFactory. Most classes are instantiated this way, but it's possible that a class without any lazy properties was never updated to use it. A tell-tale sign that an object is not instantiated via the ObjectFactory are direct calls to the constructor with new.
