### 启用代理转发的请求头 { #enable-proxy-forwarded-headers }

你可以用 *CLI 选项* `--forwarded-allow-ips` 启动 FastAPI CLI，并传入应该被信任、允许读取这些转发请求头的 IP 地址列表。

如果设置为 `--forwarded-allow-ips="*"`，就会信任所有来源 IP。

如果你的**服务器**位于受信任的**代理**之后，并且只有代理会与它通信，这将使其接受该**代理**的任何 IP。

<div class="termy">

```console
$ fastapi run --forwarded-allow-ips="*"
