!!! Note "笔记"

    注意，本例与数据库通信时使用 `await`，因此要把*路径操作函数*声明为异步函数（`asnyc`）。

### 关于 `{**note.dict(), "id": last_record_id}`

`note` 是 Pydantic `Note` 对象：

`note.dict()` 返回包含如下数据的**字典**：

```Python
{
    "text": "Some note",
    "completed": False,
}
```

但它不包含 `id` 字段。

因此要新建一个包含 `note.dict()` 键值对的**字典**：

```Python
{**note.dict()}
```

def test_create_read(app: FastAPI):
    with TestClient(app) as client:
        note = {"text": "Foo bar", "completed": False}
        response = client.post("/notes/", json=note)
        assert response.status_code == 200, response.text
        data = response.json()
        assert data["text"] == note["text"]
        assert data["completed"] == note["completed"]
        assert "id" in data
        response = client.get("/notes/")

!!! note
    Before FastAPI 0.108.0, Starlette 0.29.0, the `name` was the first parameter.

    Also, before that, in previous versions, the `request` object was passed as part of the key-value pairs in the context for Jinja2.

!!! tip
    By declaring `response_class=HTMLResponse` the docs UI will be able to know that the response will be HTML.

!!! note "Technical Details"

Wenn Sie **FastAPI** lernen möchten, ist es viel besser, das [FastAPI-Tutorial](https://fastapi.tiangolo.com/tutorial/) zu lesen.

!!! note "Hinweis Deutsche Übersetzung"

participant handler as Exception handler
participant dep as Dep with yield
participant operation as Path Operation
participant tasks as Background tasks

    Note over client,operation: Can raise exceptions, including HTTPException
    client ->> dep: Start request
    Note over dep: Run code up to yield
    opt raise Exception
        dep -->> handler: Raise Exception
        handler -->> client: HTTP error response
