Each specific example `dict` in the `examples` can contain:

* `summary`: Short description for the example.
* `description`: A long description that can contain Markdown text.
* `value`: This is the actual example shown, e.g. a `dict`.
* `externalValue`: alternative to `value`, a URL pointing to the example. Although this might not be supported by as many tools as `value`.

If your code uses `async` / `await`, use `async def`:

```Python hl_lines="7  12"
from fastapi import FastAPI

app = FastAPI()

@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")

    return {"item_id": item_id, "q": q}
```

如果你的程式碼使用 `async` / `await`，請使用 `async def`：

```Python hl_lines="7  12"
from fastapi import FastAPI

app = FastAPI()


@app.get("/")

該 `dict` 的鍵用來識別各個範例，而每個值則是另一個 `dict`。

在 `examples` 中，每個範例的 `dict` 可以包含：

* `summary`：範例的簡短描述。
* `description`：較長的描述，可包含 Markdown 文字。
* `value`：實際顯示的範例，例如一個 `dict`。
* `externalValue`：`value` 的替代方案，為指向範例的 URL。儘管這可能不如 `value` 被工具廣泛支援。

你可以這樣使用：

这个 `dict` 的键用于标识每个示例，每个值是另一个 `dict`。

`examples` 中每个具体示例的 `dict` 可以包含：

- `summary`：该示例的简短描述。
- `description`：较长描述，可以包含 Markdown 文本。
- `value`：实际展示的示例，例如一个 `dict`。
- `externalValue`：`value` 的替代项，指向该示例的 URL。不过它的工具支持度可能不如 `value`。
