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。

在大多數情況下，你會（也應該）有一個「終止代理」來處理 HTTPS，這取決於你如何部署你的應用程式，你的服務供應商可能會為你做這件事，或者你需要自己設置它。

You can start FastAPI CLI with the *CLI Option* `--forwarded-allow-ips` and pass the IP addresses that should be trusted to read those forwarded headers.

If you set it to `--forwarded-allow-ips="*"` it would trust all the incoming IPs.

If your **server** is behind a trusted **proxy** and only the proxy talks to it, this would make it accept whatever is the IP of that **proxy**.
