fastapi[standard]>=0.112.0,<0.113.0
```

這表示會使用 `0.112.0`（含）以上但小於 `0.113.0` 的版本，例如 `0.112.2` 也會被接受。

如果你使用其他安裝管理工具，例如 `uv`、Poetry、Pipenv 等，它們也都有可用來指定套件特定版本的方法。

## 可用版本 { #available-versions }

你可以在 [發行說明](../release-notes.md) 查看可用版本（例如用來確認目前最新版本）。

## 關於版本 { #about-versions }

依照語意化版本的慣例，任何低於 `1.0.0` 的版本都可能加入破壞性變更。

FastAPI 也遵循慣例：任何「PATCH」版本變更僅用於修正錯誤與非破壞性變更。

/// tip

「PATCH」是最後一個數字，例如在 `0.2.3` 中，PATCH 版本是 `3`。

- Définir l’en-tête `Cache-Control: no-cache` pour **empêcher la mise en cache** du flux.
- Définir un en-tête spécial `X-Accel-Buffering: no` pour **empêcher le buffering** dans certains proxys comme Nginx.

當使用 `response_model` 或回傳型別時，FastAPI 不會使用 `jsonable_encoder` 來轉換資料（那會較慢），也不會使用 `JSONResponse` 類別。

相反地，它會取用用回應模型（或回傳型別）透過 Pydantic 產生的 JSON 位元組，並直接回傳具備正確 JSON 媒體型別（`application/json`）的 `Response`。

## 注意事項 { #notes }

當你直接回傳 `Response` 時，其資料不會自動被驗證、轉換（序列化）或文件化。

但你仍然可以依照[在 OpenAPI 中的額外回應](additional-responses.md)中的說明進行文件化。
