### 使用 HTTPS 的重定向 { #redirects-with-https }

例如，假设你定义了一个*路径操作* `/items/`：

{* ../../docs_src/behind_a_proxy/tutorial001_01_py310.py hl[6] *}

如果客户端尝试访问 `/items`，默认会被重定向到 `/items/`。

但在设置 *CLI 选项* `--forwarded-allow-ips` 之前，它可能会重定向到 `http://localhost:8000/items/`。

而你的应用可能托管在 `https://mysuperapp.com`，重定向应当是 `https://mysuperapp.com/items/`。

通过设置 `--proxy-headers`，FastAPI 现在就可以重定向到正确的位置。😎
