    * Will have the best performance, as it doesn't have much extra code apart from the server itself.
    * You wouldn't write an application in Uvicorn directly. That would mean that your code would have to include more or less, at least, all the code provided by Starlette (or **FastAPI**). And if you did that, your final application would have the same overhead as having used a framework and minimizing your app code and bugs.

/// warning

你可以在一個 *路徑操作（path operation）* 中宣告多個 `Form` 參數，但不能同時再宣告期望以 JSON 接收的 `Body` 欄位，因為該請求的本文會使用 `application/x-www-form-urlencoded` 編碼，而不是 `application/json`。

這不是 **FastAPI** 的限制，而是 HTTP 協定本身的規定。
