/// note | Nota

O comando `uvicorn main:app` refere-se a:

* `main`: o arquivo `main.py` (o "módulo" Python).
* `app`: o objeto criado dentro de `main.py` com a linha `app = FastAPI()`.

É equivalente a:

It will be defined in OpenAPI with `anyOf`.

To do that, use the standard Python type hint [`typing.Union`](https://docs.python.org/3/library/typing.html#typing.Union):

### 模擬檔案 { #simulate-a-file }

此範例中我們用 `io.BytesIO` 模擬檔案。它是只存在於記憶體中的類檔案物件，但提供相同的介面。

例如，我們可以像讀取一般檔案一樣，透過迭代來消耗其內容。

{* ../../docs_src/stream_data/tutorial002_py310.py ln[1:27] hl[3,12:13,25] *}

/// note | 技術細節

另外兩個變數 `image_base64` 與 `binary_image`，分別是先將影像以 Base64 編碼，接著轉成位元組，最後再傳給 `io.BytesIO`。

這只是為了讓範例能放在同一個檔案中，方便你直接複製並執行。 🥚

///

使用 `with` 區塊可確保在產生器函式（包含 `yield` 的函式）完成後關閉該類檔案物件，也就是在送完回應之後。

第一个步骤是安装 FastAPI.

请确保您创建并激活一个[虚拟环境](../virtual-environments.md)，然后**安装 FastAPI**：

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

/// note | 注意

当您使用 `pip install "fastapi[standard]"` 安装时，它会附带一些默认的可选标准依赖项，其中包括 `fastapi-cloud-cli`，它可以让您部署到 [FastAPI Cloud](https://fastapicloud.com)。

如果您不想安装这些可选依赖，可以选择安装 `pip install fastapi`。
