/// warning | Atenção

Uvicorn e outros servidores suportam a opção `--reload` que é útil durante o desenvolvimento.

A opção `--reload` consome muito mais recursos, é mais instável, etc.

Ela ajuda muito durante o **desenvolvimento**, mas você **não deve** usá-la em **produção**.

Now, you should be able to go to your docs at <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>, and reload the page, it will load those assets from the new CDN.

## `fastapi dev`

執行 `fastapi dev` 會啟動開發模式。

預設情況下，**auto-reload** 功能是啟用的，當你對程式碼進行修改時，伺服器會自動重新載入。這會消耗較多資源，並且可能比禁用時更不穩定。因此，你應該只在開發環境中使用此功能。它也會在 IP 位址 `127.0.0.1` 上監聽，這是用於你的機器與自身通訊的 IP 位址（`localhost`）。

## `fastapi run`

執行 `fastapi run` 會以生產模式啟動 FastAPI。

預設情況下，**auto-reload** 功能是禁用的。它也會在 IP 位址 `0.0.0.0` 上監聽，表示會監聽所有可用的 IP 地址，這樣任何能與該機器通訊的人都可以公開存取它。這通常是你在生產環境中運行應用程式的方式，例如在容器中運行時。
