由於使用了相對 URL，若你的 API 位於 `https://example.com/`，那它會指向 `https://example.com/token`；但若你的 API 位於 `https://example.com/api/v1/`，那它會指向 `https://example.com/api/v1/token`。

使用相對 URL 很重要，能確保你的應用在像是[在 Proxy 後方](../../advanced/behind-a-proxy.md)這類進階情境中仍能正常運作。

///

這個參數不會建立該端點／「路徑操作」，而是宣告 `/token` 將是客戶端用來取得 token 的 URL。這些資訊會出現在 OpenAPI，並被互動式 API 文件系統使用。

我們很快也會建立實際的路徑操作。

#### 在 TLS 终止代理后面 { #behind-a-tls-termination-proxy }

如果你在 Nginx 或 Traefik 等 TLS 终止代理（负载均衡器）后面运行容器，请添加 `--proxy-headers` 选项，这会通过 FastAPI CLI 告诉 Uvicorn 信任该代理发送的标头，表明应用运行在 HTTPS 后等。

```Dockerfile
CMD ["fastapi", "run", "app/main.py", "--proxy-headers", "--port", "80"]
```
